14 Market Setting Feature: Is SSL Good for LightingThe emergence of solid-state is creating action in a market that has been
stale. While the infusion of electronics will result in greater intrusion
of imported products and components, the resulting overall gains will
produce needed improvements elsewhere.

22 At The Front: Europe's Take on SSLWhen it comes to more ambient, general lighting, the trend in Europe
is for LED to serve as the “bed” of the meal, allowing halogen and other,
somewhat energy-intensive lighting sources to spice up the main course.

Introducing Acrich2With No AC/DC Driver

I’m an Anglophile, and I love London, so the Olym-
pics captured my attention. But I must admit that
much of it was to point out to my kids that “I was
there.” That said, a couple of things bothered me:
some significantly outclassed competitions and
some ugly LED.
Let me set the stage: The fine folks at GE,
prior to the games, notified us that the company
supplied a number of their LED products for
various Olympic venues, including field hockey
and the general campus lighting for the Olympic
Park. They were also involved in relighting Tower
Bridge, a frequent TV cutaway icon. Being a geek,
I kept my eyes peeled. As seen in Buzz, the light-
ing of the historic Thames-spanning bridge is SSL
at its best, and its worst. The good: the elegant,
clean, white-blue lighting scheme of program “A”
really highlights the structure’s architecture. The
bad: alternate program “B” tarts it up with RGB.
Ugghh. Someone did the same thing to the Eiffel
Tower in Paris last year... But speaking of the City
of Light, there are good things to report when it
comes to SSL: Designers of the renovated W Paris
managed a subtle, even sublime application of the
technology to the historic hotel, as can be seen
in this month’s featured project. I’m not saying
the French have the English when it comes to
panache and savoir faire, but somewhere a line
must be drawn denoting an absolute violation of
style. Perhaps we need a Mr. Blackwell’s Worst
Dressed list for LED projects.
And it’s not just for projects. I feel the same
about a lot of products. So many, especially on
the retrofit side, are so poor or so badly con-
ceived that they also make me cringe. It’s kind
of funny, one of the friends of the magazine who
regularly helps judge our PIA program, jok-
ingly noted we should run another contest that

highlights the ugliest fixtures being introduced
into the market, because there are so many. Case
in point—and this was not an LED fixture, but
does illustrate the issue—in the hype following
the phase-out deadline of T12s this past July, one
manufacturer promoted a way to easily retrofit
the much more efficient T5 into a T12 troffer
without any of the hassle of a new troffer or
even a new ballast. That’s right you simply slot
the T5 into an adapter and voila, you’re good to
go. Unquestionably, this is an easy fix. But does
it remotely address the spirit of the T12 phase
out mandate? Not only do you lose a lot of light
because the T5 is covered by most of the adapter,
but the old magnetic ballast it still uses is not
efficient in any manner, nor capable of dimming,
etc. Someone I showed it to likened it to putting a
new TV on top of an old TV.
Not to belittle the role retrofit sources have
to play, as there’s a lot of wattage to be wrangled,
but it’s hard to get excited by them. I guess it’s a
question of economics. Manufacturers who have
gone down the LED path have sunk a lot of money
into it and need to get some revenue to keep
going. At the same time, LED fixtures are expen-
sive, and something not everyone can afford or
are even willing to consider given cheaper and
more budget-friendly alternatives. So where does
that leave things? Good question. In speaking
recently to Philips Lighting’s new CEO, he noted
LED is now 20% of their business and the com-
pany was involved in an interesting, LED-heavy
retrofit of a major New York-based professional
services firm that has the potential to be a model
for many corporate entities with sustainability
initiatives (You’ll have to wait for next issue for
the story--how’s that for a teaser!).
As always, the road ahead reveals no signs of
a final destination, but with enjoyable stops, such
as the Paris W, this observer suggests we just
keep on truckin.’

Calling it Like I See It
In the after glow of the Olympics, I must confess I was more intrigued by cutaway shots of London than most of the competitions. But for dignity and decorum to prevail in the world of SSL, RGB overkill has got to go.

ABoVE: the leD floodlights tested in Series 15 performed well in terms of efficacy, but did not match the lumen output of floodlights using higher wattage metal halide lamps. the approximate ranges represent luminaire performance.
Round 15 of the dOe’s CalipeR testing program took its first look at led floodlights, evaluating the performance of 10 current offerings. While several led models offered color-quality and dimmability—advantages over conventional high-intensity discharge (Hid) fixtures—the study found that led offerings face some challenges in lumen-output range and available light-distribution patterns.The report’s authors note that their first challenge lay in simply defining the category “floodlight” for the purposes of this round of research, because the term can be used to describe everything from residential security lighting to skyscraper-façade luminaires. The final definition incorporates fixtures designed to illuminate exterior surfaces, with an adjustable aiming angle. This description still includes a range of products, with distribution ranges that vary from narrow to wide in an asym-metric fashion.
Conventional offerings generally feature Hid (meaning high-pressure sodium or metal halide) or compact fluorescent lamps. Often, the same housing can be configured with a variety of lamps at different wattages, based on application require-ments. and interchangeable optics might be used to vary light distribution for the same base unit, with other accessories available to prevent glare and light trespass. in fact, the ability of current-technology mod-els to meet application needs may be one of the reasons the floodlight market hasn’t received much attention from led manufacturers, report authors note. But they also see potential advantage for led products because of their hardiness, dimmability, lack of restrike delay and consistent output regard-less of lamp orientation.
Measured output for the series 15 floodlights ranged from 773 lumens (lm) to 8,044 lm – com-parable at the high end with a 100W or 150W Hid lamp. The leds can’t yet match the output of the 400W or higher conventional floodlights, and ABoVE: luminous intensity distribution characteristics of the series 15 led floodlights and
the conventional benchmark. The values listed for the benchmark product are for the specific configuration that was tested. The benchmark is not included in the summary statistics.
ABoVE: Four of the 10 products had a wide distribution, and 8/10 products had a sym-metric distribution. This is not typical of the bulk of conventional floodlights, and may indicate an area where led floodlights need to offer added capability.

cAliPer round 15 Downlight Data
SSlBuzz:
the large number of leds required to meet higher wattage goals could mean a larger form factor and the need to run at life-limit-ing high-drive currents. While color quality isn’t always a primary concern for floodlight applications, researchers still did some benchmarking of led products against conventional offerings, with mixed results. Correlated color tempera-ture (CCT) of the leds ranged from 3646K to 6099K, with several products extending above typical findings for standard-technol-ogy products. The color rendering index (CRi) of tested led products ranged from 66 and 83, with a mean of 71. in summary, researchers found several key advantages for led products, vs. conventional floodlight offerings, including led efficacies that were equal to or better than those of traditional metal halide or CFl fixtures and power factors considerably better than those of conventional products. in addition, though tests didn’t specifically evaluate actual lifespans, the rated lifetimes of led floodlights are typically as long as or longer than conventional models. Balancing these pluses, however, were a number of findings indicating areas led makers need to address: •Lumenoutput:fewLEDfloodlightscan match the 20,000 lm output available with conventional technologies, especially without driving the leds at higher operating currents, which can shorten lifespans. •Lightdistribution:thewide,symmet-ric distribution of most tested fixtures is not appropriate for many floodlight applications. and, because led luminaires require an array of numerous, individual leds, rather than a single point source, narrow spot distribu-tions can be difficult to produce for these fixtures. •Customizability:Standardproductsare often designed with modularity in mind, so that a single housing can be configured in different ways, with various lamping and accessory options available to meet specific needs throughout an installation.•

AS ThE finAL MATChES of the european soccer cup (UeFa eURO) came to fruition, the event’s new host—national stadium in Warsaw—was well pre-pared. Boasting more than 55,000 seats and 69 vip boxes, this facility is not just the biggest of the four stadiums which poland has built for the european Football Championship, it is also an architectural masterpiece. To ensure that fans find their way to the sta-dium, the facility’s operator naRva polska chose austrian manufacturer Tridonic and its particular led technology as the lighting solution for the routes around the stadium. For safe operation even under difficult environmental conditions, an led-lit and highly robust handrail system guides fans throughout the stadium.

The city of Baku in Azerbaijan recently hosted theeurovision song Contest, a europe-wide music competition, and wanted to create an image of modernity amidst an otherwise ancient skyline. Two significant led installations add some 21st century “bling” to the city’s historic appeal. The first, the Baku Flame Towers (right), is a high-rise residential complex topping a hill overlooking the Caspian sea, with a design inspired by the country’s long-ago history of fire worship. Manufacturer Traxon created a special fixture installed behind the buildings’ windows to give the illusion of ribbons of light. Traxon also played a role in the new Crystal Hall (above), which hosted the eurovision event. The structure’s jagged architecture is highlighted by 72 of the manufacturer’s shield aC extend fixtures that can be programed to react to events occurring within the building. The result is a facade that comes to life in jewel-like fashion to brighten even the darkest winter nights.•

Concession areas at the stadium, which opened in 1991, had been illuminated by aging T12 U-bend fluorescent features, drawing 78-watt per fixture. Now 50-watt LED fixtures have been installed in a replacement project that’s drawing cheers from stadium managers. Cool White Borealis 2 × 2 LED Flat Panels from PolyBrite International now highlight the park’s concourses—visited by up to 2.9 million baseball fans annually—while Warm White fixtures brighten backrooms and workstations.

More than 2 km of GE’s Tetra Contour architectural LED lighting now follow the superstructure’s curving lines on either side of the towers and across the bridge’s walkway. Additionally, 90-watt LED floodlights, along with other lamps and fixtures, will highlight the structure’s Victorian gothic architecture. Sophisticated controls will allow London officials to transform the bridge into a city centerpiece for a range of celebrations going forward.
Additionally, the new system will provide savings to the city for years to come. It’s anticipated to reduce energy demands for lighting the bridge by 40%, compared to the 25-year-old system it replaces.•

product developments:
direct approach: new software and fabrication methods mean Led luminaire manufacturers can go to market more quickly as optics can be made without the need for molds and tooling.
A new manufacturing process promises to speed optics fabrication by working directly from 3D CAD models, without need for intermediate mold and
tooling development. The new service cre-ates lighting optics using a 3D printing process at prices com-petitive with injection molding, according to developer LUXeXceL. The process is based on software called Photopia, published by LTI Optics, a Dutch company which developed the program to allow it to study alternative lighting-optics designs prior to tooling. That company has paired with LUXeXceL, which provides printing-based Printoptical manufac-turing services. On-demand
fabrication reduces the need for manufacturers to maintain inventory stock. And eliminating the need for molds and tooling can mean getting new LED products to market more quickly. Instead, optics makers can go directly from prototype to finished product with just about any type of lens, including Fresnel, parabolic and spherical.•
managers at tokyo’s busy JiyugaokaStation have just completed an extensive lighting renovation intended to both cut energy costs and improve the experience of travelers passing through the space. Included were 29 new organic LED (OLED) fixtures and almost 1,200 LED fixtures, all from Panasonic. The OLED fixtures—available in the United States through Universal Light-ing Technologies—are installed in ticketing areas. The standard LED fixtures have been installed throughout the rest of the station, and are designed to change color tempera-ture throughout the day to both save energy and improve visual comfort. Photocells and infrared occupancy sensors help ensure ideal color temperature levels based on exist-ing natural light and the number of station occupants. The new installation will contribute to a 40% reduction in lighting energy at the station.•

The emergence of solid-state is creating action in a market that has been stale. While the infusion of electronics will result in greater intrusion of imported products and components, the resulting overall gains realized from this advance-ment in technology will produce needed improvements elsewhere, creating opportunities for new businesses to thrive.

There is no doubt that solid-state lighting
is here to stay. Lightfair 2012 was a physi-
cal presentation of the explosion in LED
and OLED products, while Light+Build in
Frankfurt edged even closer to becoming
more of an LED showcase than ever. The shows
presented a plethora of new manufacturers.
Familiar players showed that they too were in the
game. Once newbie manufacturers to this market
like Cree and Philips, now appear as seasoned
veterans. Those who once believed that SSL would
reduce the number of lighting manufacturers in
the market were left scratching their heads, as this
has just not been the case.
While it is obvious that change is happening,
questions persist as to whether there is good being
accomplished. Purists are as skeptical as ever—
evident in the critical tone of presentations and
continued pressure for standards to control the
technology. Is this consternation rational, or is this
just a case of laggards demanding proofs positive
before accepting the inevitable?
Compared to other industries, the lighting
market has been stagnant. The push for energy
efficiency in the 1980s stalled from lack of inter-
est, leaving advancements fallow. The market
laziness that followed is out of pace with global
energy conditions. SSL is a defibrillator—shocking
to life the erratic heart of lighting. That said, it
begs the question, is SSL good for the lighting
industry as a whole?
While there are hundreds of questions to be
answered when it comes to specific project appli-
cation, the core issues in evaluation of whether
solid-state is bringing good to lighting is far sim-
pler. Following is both a current assessment and a
forecast of things to come.
1) Is Solid-State Good for Saving Energy?SSL delivers a combination of high electrical-
to-photometric energy conversion (efficacy),
optical efficiency, and ease in the application
of controls. For these reasons, it has rapidly
become the technology of choice in the fastest
growing nations around the world. Conversely,
slow progress in the United States is related to
the slow pace of the economy, frustrated by the
availability of cheap energy and a general lack
of significant interest to engage the inevitable.
Compared to progress made elsewhere, the U.S.
is behind the curve in deployment, yet leads in
many areas in semi-conductor core technologies.
Today's assessment: Even though potential for
energy savings over incandescent, halogen, CFL,
and many HID systems is proven, market penetra-
tion remains low. However, changes in design
approach, expansion of available solid-state
products, improvements in product reliability
and trust, coupled with rapidly declining product
prices will change the pace of adoption rapidly.
currently
Looking out to 2017: Assuming the economy
improves, that the building market recovers,
energy prices increase, interest grows in retrofit-
ting existing facilities, and prices for LED products
continue to decline, there is no doubt that solid-
state will have a significant impact. In its report

fixture replacement, the efficacy of LED sources
increases, and the efficiency of LED luminaires
improves, SSL will improve even further.
Today's assessment: SSL presents the most
significant improvement in sustainable lighting
technology to date. Through long life, significant
energy saving, and minimal end of life waste
products, properly designed solid-state products
are good for the environment.
Currently:
Looking out to 2017: As the efficacy of LEDs
increases, the number of devices required declines
proportionally, which means smaller heat sinks
and skinnier products. This will improve sustain-
ability two fold: First, less energy use, with smaller
impact per lumen delivered; and second, over the
next 60 months, gains of between 35% and 50%
are conservatively attainable.
marketanalysis
‘Energy Savings Potential of Solid-State Lighting
in General Illumination Applications’ (Jan 2012),
DOE projects long term energy savings of 19% by
2020 and 46% by 2030 for all U.S. lighting energy
consumed.
extended forecast:
2) Is SSL Environmentally Sustainable?The concern for environmental impact of energy
efficient lighting has been raised in regard to the
widespread distribution of compact fluorescent
lamps. All of these contain mercury, with a large
portion also containing lead. Recycling products
that are composites of lead-bearing electronics
and mercury contained within glass envelopes
is problematic, requiring operational processes
that are not economically viable. Further, con-
sumers are guilty of ignoring the potential harm,
choosing the convenience of regular waste dis-
posal, where these lamps end up in landfills.
Beyond disposal are issues of manufacturing
and distribution, which is compounded by short
product life. The shorter the life of a product, the
more damaging it is from repeated contribution
of replacements. Energy consumption also fac-
tors into the equation, as electricity production
is often more damaging over a products life than
the initial product manufacturing processes.
In specific studies completed by Philips,
DOE, and the University of Pittsburgh, various
aspects of solid-state production were compared
to fluorescent, induction and HID sources. In each
case it was revealed that the production of SSL
generates slightly greater amount of compounds
considered harmful to the environment. Further,
the additional material mass of heat sinks in LED
products can result in a higher initial impact per
luminaire. However, the impact of production is
a small portion of total impact over the lifetime
of a lighting product. In the balance between
energy use, service lifetime and manufacturing
impact, LED products produce less total negative
impact, with less toxicity in post-consumer waste
than all other light sources. As the deployment of
modular components reduces the need for total
Sort out the good, the bad and the ugLyin time, as the market and manufacturers mature, the growth in approaches to delivering efficient, quality lighting is advancing. there are great products already available they're just mixed in a sea of mediocre or poor designs. Per-haps what's missing is an active lighting design community directly engaged in guiding manufacturers into new lighting techniques that couple the unique new capacities of solid state with forward-thinking lighting design.

extended forecast:
3) Will SSL Lead to U.S. Job Creation?
While there are jobs being created in solid-state
production and development, they are offset
by losses in other segments. The trend toward
U.S. corporations moving manufacturing to
Asia, coupled with aggressive government-
backed contractors offering attractive, low-cost
SSL component solutions, is creating pressure
against domestic SSL job growth. While some
portion of luminaire manufacturing will remain
in the domestic market, the electronics, LEDs,
and many of the supporting components inside,
will more than likely be imported.
For example, in 2012 Taiwan is invest-
ing $1B in LED manufacturing as part of its
economic recovery, while China subsidizes U.S.
companies to open plants there, unchallenged
by the federal government. The establishment
of UL and ETL in Asia has further increased
the availability of approved imported products,
often offered to at such low cost that creation
of a competing domestic alternative is impracti-
cal. Further, many Asian sources offer complete
product contract manufacturing, from design
engineering to finished goods. This vertical
integration is an advantage that few domestic
manufactures possess—the result of decades of
manufacturing theory favoring outsourcing over
integration.
In balance, changes in the lighting market
will likely result in reduced total employment
for production and delivery of lighting products
here in the United States. To reverse this trend
significant work in redressing integration of
manufacturing, as well as growth in individual
manufacturing capacity for producing elec-
tronic products must be addressed. This is not
to say there will be no new jobs created in SSL.
However, gains will be small, diluted by greater
reliance on imports and inevitable losses in the
sale of conventional products. Further, most
gains in SSL will be higher-level tech jobs, while
the larger population in the production ranks is
likely to shrink.
Today's assessment: On its current trajectory,
the transformation to solid-state lighting has not
been good as a significant source of net lighting
industry job creation in the United States. How-
ever, employment to deliver peripheral applica-
tion demands for design, integration, controls
commissioning, and technical product develop-
ment is emerging as an area of new opportunity.
Currently:
Looking out to 2017: The balance of employ-
ment in the lighting market will shift from
rudimentary fab shops toward more sophisti-
cated electronics integration. For some, this will
be an expansion of a trend already in motion,
where ballast, castings, extrusions and other
components are blended with domestic fabrica-
tion and assembly. For others, the availability of
complete products ready for import will create
new opportunities to deliver product unavail-
able to them previously. In all, as the growth of
solid-state expands, there will be a modest gain
in total lighting market employment, even as
imported electronics play a greater role than in
prior technologies.
extended forecast:Warm with a mix of clouds and sunny patches as far as the eye.
4) Will SSL Improve Lighting Quality?
A significant concern over SSL has been product
quality. Much of the effort of standards devel-
opment addresses the diverse range of quality
in products and early failures to deliver on prom-
ises made. As it is with conventional products,
there will always be solid-state products of poor
quality. Further, the quality of light emitted by
products is as diverse as it is with conventional
products. Several manufacturers sacrifice visual
quality for efficiency, delivering glary light
sources from arrays of brilliant dots to harsh,

Beyond disposals issues, the switch from less efficient sources has an environmental impact, in that the shorter the life of a product, the more damaging it is from repeated contribution of replacements. Energy consumption also factors into the equation, as electricity production is often more damaging over a product's life than the initial product manufacturing process. image courtesy of leDtronics

equate to the task of creating efficient products
of good lighting quality. Conversely, there are a
growing number of providers deploying high-
performance products of high visual quality.
The opportunity certainly exists to produce
improvements in visual lighting performance.
The question is whether as the technology
matures, will applied lighting quality be pursued
as a priority? Recent product introductions indi-
cate there is movement toward addressing the
qualitative values of light with the same vigor as
quantitative, which is good news.
Perhaps what’s currently missing is an
active lighting design community directly
engaged in guiding manufacturers into new
lighting techniques that couple the unique new
capacities of solid-state with forward thinking
lighting design.
Today's assessment: The focus on energy
savings and commodities has left the needs of
lighting design and lighting quality somewhat
neglected. Intrusion of hastily launched products
has flooded the market with both good and bad
offerings.
Currently:
Looking out to 2017: As the goals of energy
efficiency are met, and the market becomes satu-
rated with core commodity product, manufactur-
ers will begin to deliver greater innovation in
design to maintain growth. This will accelerate
over the next 60 months, creating even greater
improvements in applied lighting quality.
extended forecast:
5) Are Current Products Economically Viable?
Of all the qualifications applied to product selec-
tion, this is perhaps the most loaded. On the
surface, one can point to the generally higher
marketanalysis
cost of SSL products and bring to bear issues
of ROI evaluations to prove them good or bad.
However, overly simplistic comparisons fail to
capture the true costs of incumbent sources,
the escalation of energy costs we will face in the
very near future, the implications of waste, and
the reality that most existing lighting systems
are not performing as assumed. Further, using
money paid for energy as the core qualifier in
evaluating alternatives ignores intrinsic values
gained from updating lighting systems overall.
Further, adding controls integration, reducing
maintenance demand, and reducing toxic waste
are important benefits too often overlooked.
The residential market has proven itself
stubbornly committed to a light source that
stands on one core value over all others. The
incandescent lamp is cheap. While the commer-
cial market is somewhat better, far too many
decisions are made on first cost. Just as quality
lighting design produces benefits of lower
energy use, quality decision making in product
selection will produce long-term benefits.
For those unwilling to properly evalu-
ate and select products based on more than
simple first cost, perhaps the best solution is to
continue to utilize proven conventional product
technologies. At this stage of solid-state deploy-
ment, there are too many temptations to choose
low-cost offerings of unscrupulous marketers,
resulting in disappointing results. That said, the
number of solid-state products available today of
quality and substantial value is growing rapidly.
Today's assessment: Just as it is with any
other technology, solid-state includes a mix of
products from very high value to very low qual-
ity. When appropriate effort is applied to qualify
products beyond initial price, there are a great
many solid-state products that can be consid-
ered of high economic value.
Currently:
Looking out to 2017: The economic viability of
solid-state products is going to explode over the
lighting qualityThe opportunity exists to produce improvements in visual lighting performance. The question is whether, as the technology matures, will applied lighting be pursued as a priority? Recent product introductions indicate there is movement toward addressing the qualitative values of light with the same vigor as quantitative, which is good news.

next 60 months. The compounding of energy
prices going up while LED product prices drop,
coupled with greater performance per invested
dollar will create an environment that will chal-
lenge all conventional lighting technologies.
extended forecast:
In sum, the emergence of solid-state lighting is
creating action in a market that has been stale.
With opportunities in retrofitting, controls com-
missioning, and creation of all new lighting prod-
uct manufacturing to bring fresh new ideas to
the party, there will be gains made on all fronts.
While there are many new lighting products
using LEDs that are unattractive or useless, the
same can be said for many conventional prod-
ucts on the market today. Setting aside these
issues, the underlying technology is obviously
good for lighting as a whole, and over the next
five years will expand its reach and influence
exponentially.•

European legislation calling for
the phase out of incandescent
lamps has put LED directly in the
spotlight. A 2011 Green Paper
issued by the European Commis-
sion calls for “Accelerating the
deployment of innovative light-
ing technologies” mentions that
“The wide-scale uptake of SSL
could contribute substantially to
the objectives of the Europe 2020
strategy for smart, sustainable,
and inclusive growth, in particular
to its energy efficiency improve-
ment target.”
In other words, the goal by
2020 is to increase Europe’s overall
energy efficiency by 20%, com-
pared to 1990 levels.
This is not so far fetched,
as LED technology has not only
matured to a point where it is

In Europe, when it comes to more ambient, general lighting, the trend is for LED to serve as the “bed” of the meal, allowing halogen and other, somewhat energy-intensive lighting sources to spice up the main course.

provide visual comfort. From its
wide range of saturated colors to
dimmable whites in various color
temperatures, the LED is the prime
light source in many facilities rang-
ing from museums to restaurants,
such as Barbecoa (pictured on
the opposite page), designed by
Speirs+Major in London.
According to Iain Ruxton, asso-
ciate designer with Speirs + Major’s
Edinburgh, Scotland office, the
lighting design firm has been using
LEDs to some extent since 1996,
starting with very simple marker
lights. “For many years we used LED
for mostly dynamic color-changing
applications, but it was clear that
LED as a general white-light source
just wasn’t ready,” he says.
Issues included color consis-
tency, color-point maintenance,
efficiency and so-on, as well as
“frankly ridiculous price premium
which often prevailed,” which
he says made the firm consider
white-light LED to be too much of
a risk and not good enough value
for most of our clients. “In the last
two or three years, however, the
technology has matured beyond
our expectations—this was clear at
Light and Building in Frankfurt this
year, where convincing technical
lighting tools using white light LED
were presented with confidence
and maturity by every significant
manufacturer,” says Ruxton.
Between the improvements
in technology, the innovation from
the luminaire manufacturers,
the radical drop in cost and the
increasing pressure of energy leg-
islation and incandescent phase-
outs around the world, LED has
now become the firm’s first choice
for many white light applications.
“We are still using other
sources—metal halide for higher-
power requirements; linear
fluorescent for some applica-
tions, especially where budgets
are very tight; and I don’t think
we’re finished with cold cathode
yet either. But I’m amazed at how
quickly LED is pushing out compact
fluorescent—the other “low-energy
light source”—and I can’t remem-
ber offhand the last time I specified
a low-voltage tungsten halogen
lamp,” says Ruxton.
One of the advantages of LED,
says the designer, is surely the ease
of control, at least in theory. “It’s all
electronics talking to electronics,
rather than being about big chunks
of copper and chopping up line
voltage waveforms,” says Ruxton.
At the same time, the designer
warns “it can be a bit of a mine-
field,” as we’re in a transitional
period where old-style dimming
and newer kinds of data based
control exist side-by-side.
Retrofitting LED into old sys-
tems is especially thorny, according
to Ruxton. DMX-based systems
still rule the roost for kinetic

counts for RGB pixels, he says, get
high very quickly and Ethernet-
based data distribution becomes
necessary. As white-light LED for
all-round lighting applications
becomes the norm, however, Rux-
ton says DMX is overkill for what
are essentially scene-set systems,
and phase-dimming is an inef-
ficient compromise which allows
for retrofits, but doesn’t really
make sense as a best practice for
a new installation. “DALI [Digital

study on how to use LED to offset
the power consumption of decora-

The theme of Barbecoa is dis-
tinctly carnivore. Grills, barbeques

American BBQ chef Adam Perry
Lang to cook up favorite cuts of
meat. But in designing this new
London eatery Speirs + Major
were faced with the challenge of a
low energy allowance—only 20kVA
or 16 kilowatts—for the overall
illumination. This energy allotment
included the kitchen and all of the
restaurant’s decorative lighting—
most of the latter created by Tom
Dixon’s interior and architectural
design studio, the architectural
designer of the project.
Dixon designed over 200 deco-
rative pendants used in clusters
throughout Barbecoa to light the

restaurant’s interesting textures
and colors, the result of dark
gray finishes, cracked-mud walls,
exposed brickwork, and gleaming
brass with warm halogen or tung-
sten silver-crown lamps. “The Tom
Dixon pendants were designed
as part of the interior fit-out,
predominantly as sculptural forms
and material contrast, rather than
providing much in the way of func-
tional light,” says Clementine Rod-
gers, lighting designer at Speirs +
Major in London. “We worked with
Design Research Studio to advise
them on the positioning of their
decorative pendants for the best
light distribution, whereas they
were designing them more like
pieces of furniture.”
According to Rodgers, the
lighting consultants specified
lower wattage/higher-efficiency
lamps for all of the manufacturer’s
decorative pendants, and provided
most of the light from the sur-
rounding LED fittings in the design,
in order to meet the low energy
requirements.
Yet the lamps in Dixon’s deco-
rative lighting took their toll on the
limited energy allowance: “They’re

notes Rodgers, that are rated at 22

source Xicato light engines, which
produce a good diffused light.
“Having a diffused source felt less
intrusive in a restaurant environ-
ment where we wanted to be effi-
cient, but we didn’t want people to
be looking at the downlights,” says
Rodgers.
At the same time, she says
they didn’t think that the 2700k
temperature of the fixture was
warm enough, so they had a
glass filter made to warm up the
light further for the downlights
over the seating areas to add the
warmth that they would want for a
restaurant.
The AlphaLED fittings are
aligned along the walls or along
main circulation routes between
the fixed seating, while in the open
seating they are relatively evenly
spaced to provide enough light
whatever the seating arrange-
ment. Other uses of LED fixtures
comprise those behind the bar,
where linear LED uplights make
the shelves glow, and galvanized
steel tubes on the ceiling with an
LED source in the centre of each
one help light up the open seating
areas.
Museo Nazionale Dell’automobile Di TorinoAnother notable European project
craftily incorporating LED is
the recently redesigned Museo
Nationale dell’Automobile di
Torino, located in the automobile
capital of Italy. The museum takes
visitors on a chronological story
detailing the history of the car, how
it is an essential part of our lives,
and how it holds great emotional
attachment especially for the Ital-
ians who are great car designers.
This collection was lit by
François Roupinian of Lightemo-
tion in Montréal, Canada, whose
challenges included the fact that
the lighting in this permanent
architectural setting is always on,
needs low maintenance, and must
look the same for years to come.
French exhibit designer Fran-
çois Confino created innovative
scenic installations with a range
of vintage to futuristic look for the
cars. This exhibit concept allowed
much of the lighting to be inte-
grated directly into the 200,000-
plus sq.-ft. space with a mix of
fiber-optic, halogen, metal-halide,
and LED sources.
“We used a base of halogen
and metal halide, with LED for
accent lights and showcase lights
in the theatrical decor, building
fiber optics and LEDs into Confino’s
“sets” and LED strips behind the
décor for backlit elements and
focal points, as well as road signs
on poles with LEDs at the bottom,”
explains Roupinian. Control is pri-
marily on or off, while custom DMX
and dimmers control certain of the
exhibits with more dramatic light
shows.
Why the mix of sources? “The
museum was designed over five
years ago, so we specified it that
way. If we were to do it today I
would probably use more LED,”
admits Roupinian.

To help promote this agenda,
Philips, in partnership with The Cli-
mate Group, as part of the launch
of the “Clean Revolution” campaign
announced at the Rio+20 UN Global
Compact Corporate Sustainability
Forums, produced a study of LED
street lighting in 12 international
cities, including London. The
report, entitled, Lighting the Clean
Revolution: “The Rise of LED Street
Lighting and What it Means for
Cities,” involved a two-and-a-half-
year global pilot of LED lamps in
15 separate trials across 12 cities.
The intent was to explore the
global market status and potential
for LED technology and provides
guidelines for policy-makers and
city light managers who want to
scale-up and finance large LED
retrofits. Key findings:
Surveys in Kolkata, London,
Sydney and Toronto indicated that
citizens prefer LED lighting, with
68% to 90% of respondents endors-
ing city-wide rollout of the technol-
ogy. Amongst the benefits that
were highlighted in these surveys
were a greater sense of safety and
improved visibility.
He adds however, that there
is a very cinematographic feel to
the museum, so metal halide gives
a crisp, clear light, and good punch
from a high angle to light the cars
from 35- to 40-ft. above.
The lighting also lends itself to
the chronology of the automobile,
from its introduction at the turn
of the 19th to 20th centuries and
through the 1920s, when Roupinian
used more of a vintage look, with
warmer color temperatures.
To convey the transition into
the world wars and the contempo-
rary era, the light gets harsher with
a colder white, and the assembly
line of for FIAT entails bright, crisp
almost surreal light as in a factory.
The end result is a lively
museum that serves as a good
example of lighting intuitively inte-
grated into the scenic concepts, and
where illumination is called upon to
tell a story, in this case the history
of the car and man’s love affair with
the “machina.”
ExteriorsWhile Europe has produced many
dramatic and exciting facades
using SSL, it’s also embracing
LED for more mundane exterior
applications. According to Harry
Verhaar, Head of Global Public
& Government Affairs at Philips
Lighting, lighting is responsible for
19% of global electricity use and
around 6% of global greenhouse
gas emissions. Doubling lighting
efficiency globally, he says, would
have a climate impact equivalent
to eliminating half the emissions
of all electricity and heat produc-
tion in the European Union. And
like many other energy-efficient
technologies, efficient lighting
will boost global prosperity. In
the United States alone, he says,
cutting the energy used by lighting
by 40% would save $53 billion in
annual energy costs, and reduce
energy demand equivalent to 198
mid-size power stations.

TOPICS AT THE FRONT
The lifespan of LED lighting
trials ranges from 50,000 to 100,000
hours indicating a high return on
investment.
LED lighting was found to be
a durable technology with the need
for minimal repairs; the failure
rate of LED products over 6,000
hours is around 1%, compared, for
example, to around 10% for con-
ventional lighting over a similar
time period.
The LED market is at a
tipping point, with exterior white
light LEDs at the early stage of the
technology curve. Market penetra-
tion is accelerating as the market is
expected to expand by 60% by 2020.
A recent ILO report concluded that
the green economy could yield up
to 60 million jobs.
The report concludes that
LEDs are now mature enough for

tions, bring the economical and
social benefits to the masses.
The Climate Group, Philips
and partners are calling govern-
ments to catalyze the scale-up of
LEDs in cities and invest now in
order to capitalise on this and
create a significant amount of
high-value jobs across the world.
For the residents, the benefits
of LEDs are tangible: Gobind Saha,
61, owner of a roadside stall at
Rabindra Sarani India, says, “These
white lights have changed the way
my little business use to be under
the street lights every evening.
Earlier anything and everything
would look yellow in color result-
ing into a decreased purchasing
interest among buyers but now
that a buyer can clearly differenti-
ate between a green and blue, my
sales figures have gone higher.”
The Climate Group and
Philips are calling for an interna-
tional low carbon lighting standard
to be created and implemented
ensuring that citizens worldwide
have access to energy efficient
outdoor lighting.
Mark Kenber, CEO, the Climate
Group says, “This report clearly
highlights that LEDs are ready to
be scaled-up in towns and cities
across the globe. LED technology
is energy efficient, scalable and
positively impacts on the public; it
is the Clean Revolution in action.”•

The Solution: The piece de resistance of the renovation is a program-
mable wall of solid-state lighting that meanders through the entire
main level, accenting the hotel’s public spaces. Called “The Spark,” the
undulating backlit perforated metal sculpture is a beacon that beckons
from the street as an invitation to enter the 86,200-sq.-ft. contempo-
rary environment. “It creates a sense of fluidity,” says Gronda.
The W Paris-Opéra actually comprises three buildings that come
together as one triangular shape. The Rockwell Group decided to
maximize the visual impact of the central space where the three build-
ings meet. As a result, design creates a dynamic dialogue between the

building’s historic facade and the energy emanating from The Spark,
and its patterns of dots that form abstract pulsing clouds of light. “The
lights twinkling at the core of the building are a counterbalance to the
old facade.”
The Spark carries throughout the interior, bringing color and
vibrancy to the Bar, Living Room, Welcome Area, part of the restaurant,
secret corners of DJ booths, martini bars, and the dramatic double-
height area—right at the prow of the flatiron-shaped building. Eleva-
tors and staircases are all upholstered or painted red, to give the idea
that guests are walking inside the core of The Spark.
Old World, New lights
The mezzanine restaurant, led by Michelin star chef Sergi Arola, benefits from the visual impact of The Spark in its double-height entry, while the LEDs are programmed at a slow speed in the rest of the space to enhance a relaxing mood.
The Story Behind the Wall
Created in conjunction with
Frandsen Project Lighting in
Horsens, Denmark, the 3,000-sq.-
ft. expanse for The Spark wall
stretches over six meters high
at its tallest, and measures
two-and-a-half to three meters
elsewhere. The tallest section
stretches from the ground floor
to the mezzanine, with a large-
scale column that can be seen
from the street. “It is visible from
all angles,” says Thomas Hansen,
principal at Frandsen Project
Lighting, pointing out that there
are more than 15,000 LED units
in the hotel, including not only
the Spark, but custom golden
pendants, spheres, and chande-
liers elsewhere in the hotel.
The Spark features LEDs
attached to each custom-made
section of the wall, creating a
single curved unit. “This curving
effect was one of the biggest
challenges as the plates had to
be flexible enough so they could
be curved on site,” says Gronda,
noting that all of the LEDs have
been installed mixing RGB and
white LED to create the move-
ment of The Spark. The lighting
is covered with a black lacquered
metal plate that is perforated to
follow the design pattern and act
as a diffuser for the lighting. “We
used four different perforated
plates that, when rotated, turn
into 16 different patterns,” says
Gronda.
A special piece of hardware
was designed in order to hide
the places where the plates are
attached to one another. By re-
moving any single plate, Gronda
notes, the area behind the Spark
Wall can be accessed. The LEDs
are the same throughout the
installation but are programmed
differently to achieve different
colors and speeds depending on
the area of the hotel.
According to Hansen, there
is also a white acrylic diffuser as
one of the layers of The Spark—
along with the perforated metal
plates—so that the LEDs are not

A serpentine black resin counter-top anchors the bar area. its shape resembles a molten sculpture, as if in reaction to the energy emanated from the Spark, which continues through this space. this wall of light has also effected many of the elements in this space: furniture appears to be melted and transformed; custom ball-pendants echo the pattern of the Spark; wood molding on the ceilings is incomplete when closer to the wall; in other words. the Spark served as a catalyst for the other design elements.

“The first version of the
design had the acrylic on the

the mock-up that we built, so it is
behind the perforated metal,” he
says.
The LEDs themselves are
IP67 rated and installed 20 to 50
cm apart, screwed directly into

cost solution.
For control of the LEDs,
Hansen turned to Lutron in
London, shipping them a custom-
designed control unit that could
be adapted to the overall Lutron
control panels for the hotel.

contemporary boutique hotel.
“There were a lot of re-

were adapted to meet these tech-
nical challenges,” he points out.
The Right Touch
In a clear case of historic charm
meets hipster hotel, the design of
the W Paris-Opéra has harnessed
the LED as a major design ele-
ment, using this low-energy light
source to add a high-style sparkle
to its interior, and spill out into

The oversized undulating wall of light, according to architect Diego Gronda, can transform based on season, event, or time of day, creating a festive and celebratory atmosphere and bringing the historic building to life with sophistication and a glowing vibrancy. “The Spark is programmed at different speeds depending on the area,” says Gronda. “For example, a slow, welcom-ing motion in both the welcome area and the restaurant provides a relaxing mood.”

principal at Frandsem Project Lighting.
AROLA RestAuRAnt
Arola, the hotel’s signature restaurant by Sergi Arola, a two-starred Michelin executive chef, also sparkles with LEDs. “The restaurant at the W needs to be operative throughout the day and part of the night,” says Rockwell Group designer Maria Brime. “This meant that we had to give several moods based on time of the day, and of course based on the occupancy. The Spark changes color and speed depend-ing on the vibe of the place, as it needs to be very soft and slow at breakfast, and as the day goes on into the evening, more vibrant colors and higher speeds were selected.” As the building dates from the mid-19th century, one of the biggest challenges was to give the space a continuity, using The Spark to provide a visual feeling of one space instead of a series of different rooms. “The Spark gives a lot of flexibility to the restaurant in terms of lighting, transforming the space completely depending on the time and/or the event, but never losing the connection with the historical details of the building,” adds Brime.

It’s not because she exhibits art that is deemed
radical or spurious, but when it came time for
Canadian artist and gallery owner Wendy Waco
to lease space at the renovated Fairmount Jas-
per Park Lodge in Jasper National Park, Alberta,
all that was available was a windowless, pie-
shaped section in the lower level retail arcade of
the main building.
Waco, who operates two other galleries in
resort destinations, had hoped she could take
advantage of daylight and the surrounding
Canadian Rocky Mountain vistas. An art gallery
in an underground space wouldn’t exactly fulfil
her ambitions—or would it?
Not long after she committed to the
2,250-sq.-ft. space, she attended a store design
conference and attended a presentation by
lighting designer Bernard V. Bauer of Integrated
Lighting Concepts, Westlake Village, California.
Impressed by his retail projects, she approached
him after the session and asked him if he would
he be willing to take on the challenge of creating
the lighting for below-grade art gallery.
Bauer recalls Waco’s main driver was to
create a daylight ambience to show the art works
to their best advantage. Such an effort, he says,
would require a combination of pushing the tech-
nology of 2010 and the aesthetics of multi-media
art. He accepted her invitation to visit the site.
That initial visit wasn’t promising, as add-
ing to the challenge were the physical restric-
tions of the space. “Overhead was a complex
existing ceiling substructure of low beams and
utility pipes,” Bauer says.
Ceiling heights range from a maximum of
11 ft., 6 in. down to 7 ft., 8 in. His objective was
a lighting scheme that would produce a smooth
physical and visual transition for visitors from

ups for light fixtures and faux skylights.
Ringing the “skylights” are white LED
panels in three different lengths. “At noon, the
luminaires respond to the programmed control
system to produce illumination at the 75- to 100-
fc level. At dawn and dusk, the simulation level
dips to 10 fc. During evening hours, the ambient
lighting level is 15 fc to 20 fc in the gallery and
faux skylight areas,” Bauer explains.
Art works in the central display area are
illuminated at less than 50 fc level utilizing two
types of tracks containing white LED PAR display
luminaires. PAR 30 and PAR 38 lamp holders
have similar spread and shaping lenses and
glare shields. When needed, additional display
illumination can be beamed from 17-watt PAR
38 narrow floods and 13-watt PAR 30 spots and
floods. Display vitrines are illuminated by LED
puck lights. Wall-mounted shelving for small art
pieces have LED strip channels placed under-
neath the shelves. Both are rated at 3000K and

the out-of-doors into the below-grade art gallery.
His solution was based on a technical
representation of daylight by creating faux
skylights that would mimic the daily movements
of natural exterior daylighting. He mapped out
the existing paths of the piping and the location
of the beams and then calculated the placement
of the faux skylights and the exhibit spaces.
Color and intensity of light was choreo-
graphed to simulate day, dusk and evening
hours. Tunable LEDs were Bauer’s choice for the
entire gallery’s public spaces. Citing their long
life, energy efficiency, and dimming flexibility,
he used LEDs, with a CRI of 85, beamed at 6,500K
to simulate daylight conditions. These fixtures
could be modulated to 2,700K and dimmed 10%.
To create a smooth architectural surface,
overhead, a finished gypsum board ceiling was
installed with allowances to accommodate pop-
In the Zone
Bauer divided Mountain Gallery into a series of
three exhibit zones. For the ambient lighting in
the low-ceiling gallery, fixed lighting is on dur-
ing business hours. Museum-quality accent and
display fixtures have on/off controls and are dim-
mable. Narrow flood lamps simulate incandescent
accent lights for hanging art and sculpture.
At the entry adjacent to the main stairs is
zone 1. LED panels are synchronized to the adja-
cent “daylight” to shift chromaticity and
intensity: Light levels, from 50 fc to 100 fc; 4000K
to 6000K daylight simulation; when dimmed to 10
percent, shifts to 2700K.
In zone 2, in the relative center of the space,
high ceiling and simulated daylight is produced at
gallery display, programmed to be synchronized
with zone 1 under normal conditions. Lighting
level is boosted when the space is used as a work-
ing artist’s studio.
Zone 3, is similar to Zone 1 and is synchro-
nized with outside daylight as in Zones 1 and 2.•

The Great Fire of 1871 swept most of Chicago
clean. In its wake, municipal officials quickly real-
ized the city needed to change the way buildings
were planned and built. One of the first struc-
tures to emerge in this more safety-conscious
era, was the Rookery, designed by Burnham
& Root to be the headquarters for the Central
Safety Deposit Co. Radical at the time, the firm
proposed to make the building economically
viable by extending its height to 11 floors by uti-
lizing steel frame construction for the interior,
combined with masonry load-bearing walls.
Natural lighting, due to issues with still-
emerging electricity, also played a key role in
the design, as its curtain wall features large
expanses of windows. This allowed light to be
captured even where surrounding buildings cast
their shadows. Today, the Rookery’s neighbors
tower over it, negating its nighttime presence,
something current property manager John Buck,
sought to amend. Buck engaged New York-based
Office for Visual Interaction (OVI) to devise a plan
sensitive to the color, carvings and architectural
details of the structure.
OVI, led by Jean Sundin and Enrique Peini-
ger, had previously served as consultants on
the re-lighting of one of Canada’s most historic
structures—the Parliament Building in Ottawa.
But this time, the designers did not have the
benefit of accurate as-built drawings. “Key to the
success of the project was to achieve the desired
lighting distribution while meeting the Chicago
Landmark Commission’s preservation regulations
that lighting hardware not be visible by pedes-
trians and did no damage to the facade,” says OVI
principal Enrique Peiniger.
OVI’s plan was to position miniature lumi-
naires at every third level so that the illumination

would graze the facade and detailing around the
window frames with a soft glow of light. Line-of-
sight studies were conducted to guide place-
ment of fixtures that would not be seen from the
street. OVI collaborated with Zumtobel to create
an LED fixture that was small enough to fit the
tight mounting dimensions, 1.5-in. high, with
enough power to beam upward from its posi-
tion on the granite window sills. A 3,000K warm
white, high-performance 14.4-watt luminaire,
the newly named ROOK LED, was mounted on a
custom telescoping mounting arm was assem-
bled and mock-ups were tested at the site. “The
telescoping design accommodates the different
ledge conditions and is lockable for field adjust-
ment and aiming,” Peiniger indicates.
Attached to the mounting bracket are poly-
urethane feet that protect the ledges from direct
contact with the bracket’s metal elements.
Because of the variation in placement on
the differently dimensioned ledges, OVI’s field
surveys produced data needed for accurately
redrawing the site conditions. During the mock-
up stage, the team tested special optics to maxi-
mize the amount of light on the façade, minimize
power consumption, and prevent spill light into
the night sky. For the final version of the fixture,
Zumtobel specialists employed micro-optics to
flatten the cone’s elliptical beam to extend to its
proposed three-story-high illumination thrust
without light trespassing and prevention of
glare reaching late-working tenants.
Peiniger points out that the luminaires,
which are small enough to fit into the palm
of a person’s hand, produce a total of 2,304
watts for “gentle yet precise illumination of the
facade, while highlighting its fine stucco work.”
Zumtobel’s ROOK LED custom design has been
incorporated into its standard product portfolio,
available as Elevo LED Spotlight.

While a great deal of attention is paid to LED lumen depreciation, this
is only one indicator of serviceable life. There are other failure modes
as important to survivability. The following outlines basic tests used
for reliability projections worth knowing more about.
DVT: Design Verification Test.
Test of products within the prescribed design parameters, includ-
ing input voltage, current, circuit protection, environmental condi-
tions (heat, moisture, etc.) Establishes the product is performing as
designed. This includes testing of products under all intended applica-
tion condition extremes.
RDT or ALT: Reliability Demo Test or Accelerated Life Test
Testing of product in such a way as to accelerate exposure to condi-
tions within the design parameters for the product, without exposing
it to stress outside intended design limitations (example: Salt spray
testing of paint finishes).
HALT: Highly Accelerated Life Testing
Test the product in such a way as to over-stresses it to force failures
and expose weak links and failure cascades of dependent components
to isolate and expose root cause failures (example: Testing a product
under higher and higher ambient temperatures until failure). This is
used to establish components and assembly or construction issues that
require corrective action to increase the toughness of a product.
HASS: Highly Accelerated Stress Screen
In-line testing based on results of HALT data, stress products to the
point of exposing failures without reducing the service life of the
product itself. This is generally applied to small production runs and
products where any failure could be considered critical (example: A
24-hour elevated temperature burn in of all products produced before
shipping to customers).
HASA: Highly Accelerated Stress Audit
This test is similar to HASS, but applied to a statistically significant
sampling of production products. Generally used for large production
runs to reduce the number of products actually tested.
ESS: Environmental Stress Screening
Testing of all or a portion of products in production within prescribed
environmental application conditions. May or may not include stressed
testing outside design limitations. Purpose is to create a simple in-
process test to weed out product failures (example: Testing for water
Product Reliability: It’s All About Testing
A handle on LED testing nomenclature goes a long way
leaks for outdoor product) to produce greater confidence in delivered
product reliability.
MTBF: Mean Time Between Failure
MTBF is a statistically derived prediction (from other test data col-
lected) of elapsed time between inherent failures determined by test-
ing a population of samples over time.
MTBF = (number of products tested × operating hours)/number of
failures observed
This is generally applied to serviceable products that can be repaired
and is an indicator of reliability. MTBF cannot be assumed to indicate
actual service life, as it represents a period of time when a certain
number of products will have failed—regardless of whether that num-
ber of failures is acceptable in application.
FMEA: Failure Mode Effects Analysis
This is the analysis of any system in order to determine the impact of
failures of individual components—to establish a realistic prediction of
useful service life. This requires inclusion of actual testing combined
with statistical analysis. In addition, this will include acceptable failure
modes and periods, as well as failure tolerance factors. For example,
critical systems with zero failure tolerance will produce shorter FMEA
service life results, than products used where a percentage of failures
is acceptable.
LM-80 + TM-21: Measuring Lumen Maintenance of LED Light
Sources + Projecting Long Term Lumen Maintenance of LED
Light Sources
Test and lumen depreciation projection protocols for establishing
lumen depreciation of LED light sources. This does not result in mea-
suring actual product life, but does provide information that is used in
conjunction with other test results to establish expected lumen degra-
dation of a product put in service.
Product failures are frequently the result of short cutting reliability
testing, a lack of understanding of reliability testing, or not being fully
aware of variables that stress a product. The hallmark of a high qual-
ity manufacturer is their investment in testing and ongoing quality
checks, so asking them about their procedures and results is a worth-
while exercise. Testing does not require large facilities or expensive
labs, but does require a commitment to customers that includes insur-
ing that the product delivered will deliver promised results.•

High-bay lighting is the most common type of lighting used in com-
mercial facilities that have high ceilings and require high foot-candle
levels. They are ideally suited for large spaces with mounting heights
between 15 and 40 ft., and ambient temperatures between -4°F and
131°F. While high-bay lights have traditionally used high intensity dis-
charge (HID), metal halide (MH) or fluorescent lamps, many specifiers
and facility managers are changing to LED luminaires.
Properly designed and engineered LED-based high-bay lumi-
naires can offer big advantages for commercial applications. However,
it’s important to consider LED luminaires that take a systems-level
approach that includes driver design and thermal management, rather
than just retrofitting LED “bulbs” into existing fixtures.
LED Lamp LifeCorrectly designed LED will not fail catastrophically, but rather slowly
dim. LED luminaires are determined to have “failed” when light output
reaches 70% of original output. In fact, well designed fixtures can last
over 50,000 hours making non-scheduled equipment downtime due to
lamp failure nonexistent.
How long is 50,000 hours? Based on the length a fixture is illu-
minated per day, here is what a 50,000 lifetime translates into on an
annual basis:
Hours of Operation: 50,000 hours is:
24 hours a day 5.7 years
18 hours per day 7.6 years
12 hours per day 11.4 years
8 hours per day 17.1 years
With LED luminaires, maintenance costs are minimized as relamp-
ing may not be required during usable lifetime of the product. Another
important consideration given that high bays are ceiling-mounted and
may need the use of a lift to change out the burned fixture.
LED Illumination – Ready for Prime TimeDebate continues about whether LEDs have the output in lumens.
Through advancements in technology and manufacturing, bright white
LED luminaires for commercial lighting applications are in the market.
Recent legislation in the United States has led to the phase-out of
mercury vapor ballasts and lamps as well as 150 to 500 watt MH lumi-
naires. LED technology fills these needs, while far exceeding govern-
ment mandated efficiency standards.
An LED luminaire incorporates an array of point sources that
direct light precisely where it’s needed, with very little scattering or
loss. Light distribution is controlled by the placement of LEDs, as well
as by efficient use of optics.
LED High Bay Luminaires – Ready for Prime Time
Instant-on and reduced maintenance big sells for LED in Hi Bay
Since traditional lamps are high-intensity near-point sources, the
optical design for these luminaires causes the area directly below the
luminaire to have a much higher illuminance than areas farther away
from the luminaire. In contrast, the smaller, multiple point-source
and directional characteristics of LEDs can allow better control of the
distribution, with a resulting visible improvement in uniformity.
LED luminaires use different optics than traditional lamps
because each LED is an individual point source. Effective luminaire
design exploiting the directional nature of LED light emission can
translate to lower optical losses, and higher luminaire efficacy. Con-
sider of a couple of spaces that could benefit from LED:
Warehouse LightingHere’s where LED luminaires’ dramatic energy efficiency really makes
an impact. Typically, lighting is viewed as a fixed expense, but it
shouldn’t be; energy costs can be dramatically reduced – up to 75%–
and maintenance can be virtually eliminated through the installation
of LED luminaires. Additionally, paired with occupancy sensors and/or
dimmable components they provide even greater energy efficiency.
Further power savings are achieved from turning off the fixtures
when not in use. Workers often leave the traditional lights on continu-
ously because they take so long to warm up to full brightness. LED
luminaires light immediately, eliminating the need to have them on all
the time.
Many LED retrofit installations don’t require a one-to-one replace-
ment so the combination of using fewer fixtures for shorter periods
of time provides a lower energy bill and significantly reduced mainte-
nance expense.
Cold Storage Conventional lighting and refrigeration systems typically work against
each other. Lighting systems generate heat, which the refrigeration
system needs to remove. In addition, lower temperatures typically
reduce the efficacy of lighting systems. Therefore, more power is
required to generate the desired illumination, which in turn, increases
the load on the refrigeration system.
Facilities can save tens of thousands of dollars in yearly electric
costs, and cut harmful emissions by thousands of tons by implement-
ing a handful of simple, cost-effective efficiency measures to reduce
electrical consumption and have a payback period of three years or
less such as installing LED luminaires.
Only certain technologies, such as LED luminaires, are capable of
functioning for cold storage needs at temperatures that range from
zero degrees to -40°C. •

letters to the editor:
FIndIng FlIcker FrustrAtIngI read the latest [ Aug. 21st] issue [of the SSL Online Newsletter] and the story on ASSIST’s new flicker studies and recommendations and I must admit that I am a bit disappointed with their model. They fitted the linear model into data which is definitely not linear. Consequently, if one tries to predict thresholds for 100Hz the value comes up negative. Further on, it seems that they didn’t take into account the effect of duty cycle at all. Finally, the model is only valid for square waves. Having all these in mind, what’s the range of applications for such a model?
With kind regards,gosia perz

SSlObserved:
sion of electronics unpleasant when all I really
want is a simple, easy-to-use finished product. It’s
hard not to romantically look back at the 12-volt
halogen-era as a simpler, more fun time. I lighted
conference tables with automotive headlamps,
and sold sculptures made from hardware store
copper wire, without a care to heat sinks or cur-
rent controls. At times, dealing with solid-state
tech providers is like asking a parochial school
nun for a red crayon. By the time you get done
with the inquisition over the use of said crayon
and how many inches are to be drawn with it, the
inspiration has passed. On the other hand, LEDs
are really neat-o little gadgets, and once you get
used to their queer behavior, wreck a handful of
them, and burn your fingers on inadequate ther-
mal pathways, they can open new doors in design.
Over the last decade I have invested a
great deal of personal time and resources in
understanding, experimenting and exploring the
potential of SSL. I can say without doubt, it’s not
a perfect technology, not even close. But, in com-
paring this new thing to the old things I have had
to work with, I find no interest in going backward.
As a renaissance autodidact who frequently
blends blacksmithing, lathe work on vintage
machines, modern CNC machining and 3D plastic
modeling processes with complete disregard for
the traditional boundaries being stomped upon
in the doing of these things—objectivity is about
being open to any and all potential. This means
thinking outside boxes.
Of course there are times when aspects of
solid-state are infuriating. The presentation of
When writing about topics involving solid-state,
I attempt to be as objective as possible. While
some interpret objectivity as balancing nega-
tives and positives, I feel that objectivity does not
always work that way. There are many discus-
sions where there is only one side. For example,
there is no case for opposing the supposition
that children should not be thrown from moving
vehicles. While I am sure there are parents on
long road trips that might argue the point, the
topic of airborne children has but a single dimen-
sion. Of course, in the Twitter-verse, there will
be mention of baby birds thrown from nests, or
skydiving families tossing a reluctant child from
an airplane, and examples of how being thrown
from a car as a youth changed someone’s/uncle’s/
friends/neighbor’s/teacher’s life in some fantasti-
cal way. This is not objectivity; it’s just the idiocy
of the inter-web.
There are certainly components to solid-
state lighting that have several dimensions
worthy of consideration. I, for one, find the intru-
glare bomb products as lighting advancements is
a particular sticking point. Another is the explo-
sion in non-lighting members of the solid-state
community, expressing their neophyte views on
lighting topics, drawn from brief forays to the
touch stone of SSL engineers—the Home Depot.
The technology is also over-sold, over-hyped, and
filled with misleading marketing fictions, regard-
less of efforts to control it. It’s a light source, a
good one to be sure… but just a light source, not
a cure for cancer, or savior of the universe as we
know it.
Yet, when writing on this topic, I frequently
find myself cheering it on. It’s hard not to see the
potential in it. I am normally not the cheerleader
type, and certainly don’t own pom-poms. My
disposition is more suited to being skeptical and
critical. Give me anything good and I can point to
three things that realistically put it in its place.
Yet, for solid-state, I find the balance between
being critical and enthusiastic weighed toward
the positive. It’s just cool, even if the majority of
its uses today are a complete bore to me. So, when
I feel my objectivity sliding too far to the flowery
meadow-frolicking side, I visit the websites of new
LED product marketers and read spec sheets, or
open emails from importers who think I am their
friend. That works to break the cheery mood and
gives me a good chuckle every time.•
about the author: Kevin Willmorth, a lighting expert and fixture designer, has been instrumental in helping create a vision and mission statement for Architectural SSL.
Despite a general disposition toward skepticism, I find myself frequently cheering on the advancement of solid-state lighting. It’s a technology that’s by no means perfect, but I’d rather move forward than backward.
