Lighting and Energy
22% of US electricity usage is for l ighting
30% of electricity in buildings
Widespread LED deployment by 2025 can:
Save $115B in electricity
Eliminate 258 M ill ion metric tons of greenhousegases
Eliminate the need for 133 coal-fired 1000 MW pow erplants
Incandescent l ight bulbs use 92% of
electricity to generate heat only 8% for l ight
LED Lighting is the highest-impact option to
reduce our electricity consumption

LED General Lighting Why Now?
Technology has advanced dramatically to delivervalue to new and emerging applications Reliability and lifetime are advantages for LEDs
Lumens/ watt has improved significantly
White light quality & stability
Economics are starting to make sense
LED light delivers Total-Cost-of-Ownership savingsthrough: Maintenance avoidance
Energy savings
Regulatory & Green impact CA Title 24; EnergyStar

Basic Advantages of LED Light
Are very energy efficient ~100 LPW (sti l limproving)
Are directional No w asted light, any patternpossible
Have very long lifetime >50,000 hours to70% LM
Are inherently rugged No filament to break Start instantly nanoseconds vs. > 10 min
(HID)
Are environmentally sound no Hg, Pb, heavymetals
Are infinitely dimmable, controllable Newlighting features, power savings
Love cold temperatures No cold startingissues
LEDs can technically replace ANY incumbent lighting technology.When will LEDs replace all light bulbs, not if
