More site electricity is consumed for lighting than for any other end use.

Energy Information Administration, 2003 Commercial Buildings Energy Consumption Survey

~40 % of electrical use


The Opportunity Changing sources in energy production,

electricity de-regulation, power pricing, federal and state energy policy, available lighting technology and business and public cost consciousness create a ‘perfect storm’ for economically introducing enhanced lighting solutions


Typical Building Opportunities• Lighting upgrades

– Upgraded Retrofit or New Technology– New Controls

• Building management – Daylight harvesting– HVAC integration

• Motor replacements • Utility systems

– Compressed air• Power factor improvements

Types of Lighting

• Standard fluorescent– Mixture of low pressure mercury vapor and inert

gas (such as argon) in tube. Phosphor powder coating on tube fluoresces excited by UV emitted by mercury vapor when current applied. Current controlled by a ballast.


• Down lights/track lighting– Same technology as above – Compact fluorescent– Halogen

• High intensity discharge (HID)– Mercury vapor, metal halide, and high

pressure sodium lamps

T8 Lamps and Ballasts T8 Lamps – Latest Technologies

• New 2nd, 3rd & 4th Generations• 25w, 28w, 30w & 32w versions• Higher Lumen Output• Better Lumen Maintenance• Longer Life


T8 Electronic Ballasts• Ballast Factor – Determines Light Output &

Wattage

• LBF-.77 ∙ NBF-.88 -.90• HBF-1.18 -1.20

• Instant Start – Lower Wattage, not recommended for use with occupancy sensors

• Programmed Start – Longest Lamp Life and Excellent Energy Savings, compatible with sensors


T8 Lamps and Electronic Ballasts

Instant Start Pro Start


Retrofit Kits

Add occupancy sensors for an additional 30%-40% savings


T5HO Fixtures

Generic HID Fixture

Generic T5HO Fixture


T5HO Fixtures vs. 400w HID Fixtures• Energy Savings – 458 Input Watts Vs. 240 Input

Watts• Dramatic Color Improvement - Read Labels

More Accurately• Improved Light Output - Both Horizontal &

Vertical• Program Start Ballast Technology - Long Lamp

Life


T5HO Fixtures vs. 400w HID Fixtures• Occupancy Sensors Turn Off T5 Fixtures When

Not Needed - Fixtures Turn On Instantly When Area Is Occupied

• Low Lamp Lumen Depreciation - Increases Time Between Relamps

• Substantial Maintenance Cost Avoidance - 5 Year Ballast & 2 Year Lamp Mfr. Warranty
