Questions?
Industrial Lighting - What matters most
Industrial customer concerns:
Save moneyEnergy savingsMaintenance savings
I need more light where I need itThis is key
More light = better productivity and safety
Agenda
• How do we perceive light: CRI - Kelvin• Existing technology review• LED
– What it is– How to compare– What is important in a fixture
What is CRI and Kelvin temperature
Kelvin Temperature: what comes out. Warm vs cool light
Eye sees better in blue light
CRI: what we see Range 0-100
Measures intensity at specific wavelengths
Based on incandescent Imperfect scale
Existing In your facilities
• Fluorescent– Instant on, hard to dim, lamps 4-6 years, lumen depreciation
• HID– Long warm up, high LPW, MH 24,000 life, HPS yellow
• Solid State: LED– Instant on, high LPW, easy to dim, OCC, minimal maintenance
LED
Components of an LED fixture• LED : Light Emitting Diode --- Lamp• Driver --- ballast• Surge Protector --- drivers are not as robust as magnetic
ballasts. – Helps suppress transients (not the same as a fuse)
• Optic – still very important• Housing – LED fixtures still need a housing
How to compare LED for IndustrialWhat matters most
• Lumen output
• Watts consumed
• Energy efficiency (lumens per watt)
How to compare LED for IndustrialWhat matters most
LIFE – LED is a whole new ball game. This is NOT HID
– When will the lights go out?? With LED they don’t go out (unless there is a problem)
– Driver life 100,000 hours
– Optic life- so long may need cleaning before replaced

Lumen Maintenance curves define LED life. And this varies with temperature.
LED Lamp Lumen Depreciation LLDL70
Light Loss Factors and LEDWill it pass the test of time?
• LED Light Loss Factors LLF– LLD: Lamp Lumen Depreciation (LED L70 / TM21)– LDD: Luminaire Dirt Depreciation– BF/DF: Ballast Factor (LED Driver Factor DF = 1)– TF: Thermal Factor (** BIG DEAL IF HOT)
Used to predict long term performance
Traditional: Lumens Out = Lamp rated lumens * LLD * LDD * BF * TFLED: Lumens Out = Initial Lumens* TM21 * LDD * DF * TF
Fixture efficiency• Get the lumens OUT!
• Typical office – 75-92%• Typical highbay – 55-85%• Typical cobra head – 50-80%
TraditionalLED
Optics – Life and PerformanceCustomer: “I want an LED that will last 100,000 hours.”Lets use an optic that will too.
What optics affect: Maintenance – does it get brown, cloudy or brittle?
Lumen output and efficiency – careful with frosted lenses
Glare - Prisms / Frost / Flat glassDoes it matter if it’s glary?
Distribution – where is light going?I can see the thing I am trying to look at. YAY!!
Distribution PatternsLight where you want it
This is the exact same lumen fixture
Which is which?
• reflector, symmetric• refractor, symmetric• reflector, asymmetric

What LED has to offer
• Benefits– Provide strong down light – great for high mounting heights – check
optics– Can be great for ‘hot’ or cold applications – check temp ratings – Can be a small surface area so it works well in dirty environments– Instant ON – no warm up needed to hit full bright. – Dimmable to 10% - additional energy savings– Long Life – 100,000+ hour lamp life / 100,000 hour driver life– Can have good lumen maintenance – maintains high lumen output over
the life of the LEDs (TM21)
