Adjust lighting to your actual needs.*

Use free daylight during the day.


Replace incandescent light bulbs.

Use compact fluorescent lamps (CFLs) wherever appropriate. CFLs cost about 75% less to operate and last about 10 times longer than incandescent bulbs.


Consider upgrading to T8 (1" diameter) fluorescent lamp tubes with solid-state electronic ballasts.

You can dramatically reduce maintenance by eliminating lamp replacement, while preventing up to 500 pounds of greenhouse gas emissions. Also, T8 tubes are more efficient than older T12 (1.5" diameter) tubes with magnetic ballasts.


Install switch plate occupancy sensors.

Install sensors in proper locations to automatically turn off lighting when no one is present and back on when people return. Don't install the sensor behind a coat rack, door, bookcase, etc. It must be able to sense an approaching person's motion to turn on the light before or as they enter an unlit area.


Install ENERGY STAR®-certified exit signs.

ENERGY STAR-certified exit signs can save up to $10 per sign annually in electricity costs.
