Turn off lights when not needed. For example, turning off fluorescent lights saves energy, extends overall lamp life and reduces replacement costs. Myth: Turning lights on and off uses more electricity than leaving the lights on.
Reduce or replace inefficient, outdated or excessive lighting within your building.
Evaluate new technologies that may need fewer fixtures and/or fewer lamps within existing fixtures when replacing old lighting equipment. Ensure that light levels will remain at adequate levels before changing out technologies and/or reducing number of lamps.
Where practical, replace incandescent lamps with compact fluorescent lamps (CFLs). Ensure you install compatible dimming technology if CFLs are used along with a dimming system.
When fluorescent T-12 lamps burn out, consider retrofitting fixtures with T-8 lamps and changing from magnetic ballast to electronic.
Replace incandescent "EXIT" signs with LED signs. LEDs use about one-tenth the wattage and last 50 times longer than incandescent-lamp signs.
Install lighting occupancy sensors that automatically turn lights on or off, depending on occupancy. These sensors work well in areas such as conference rooms, break rooms or individual offices that are not occupied continuously.
Take advantage of natural daylight. Turn off or dim electric lighting when adequate sunlight is available to illuminate interior space.
Manage outdoor lighting. Ensure outdoor lighting is off during daytime.
Clean fixtures and replacing any yellowed or hazy lenses and diffusers twice a year to ensure you are getting the best possible light.
