Compact fluorescent lamps (CFLs) use 75% less electricity than an equivalent incandescent lamp, which makes them great for energy savings. However, they do have a few requirements to keep in mind to ensure a successful application:
Placement & Use: The life of a CFL is reduced by moisture, excessive heat, and frequent on/off cycling. Avoid installing recessed lighting fixtures (can lights for example) where heat cannot be dissapated. Most CFLs are not compatible with dimmer switches.
Light Color: A common complaint about CFL's is that they are "too cold" or "too white". A lamp's rated color temperature indicates the lamp's "warmth"; for light similar to a traditional incandescent, look for a color temperature of 2700K or lamps labeled "warm white".
Safety: CFLs do contain a small amount of mercury (~5 mg) which is released if the lamp is broken. See the EPA's recommendation on how to deal with a broken CFL.
Disposal: Because of the mercury contained by the lamp, CFLs must be disposed of as hazardous waste. For on-campus disposal, please fill out the Hazardous Waste Pickup Request form. For personal use CFLs, Home Depot accepts burnt out CFLs for proper disposal at no charge, as does Allied Waste at their recycling center.
Seattle Power and Light has a great site dedicated to CFLs.

We know you have good ideas on how to save energy on campus, so let us know what they are and you could win a $50 gift certificate to the OSU Bookstore!
Submit your great ideas to Greg by midnight on February 18th for a chance to win. The winner will be announced on February 28th, the last day of the Challenge.
Conservation concepts will be judged on originality, overall impact, replicability, ease of implementation, and visibility.
February 2nd: Leaving the room for more than 10 minutes? Turn those fluorescent lights off! The energy consumed during the ‘power surge’ at start-up is equal to 5 seconds of normal light operation. Then why wait 10 minutes? Frequently cycling fluorescent lights on & off reduces lamp life.
February 3rd: Fluorescent bulbs still use energy even when they’re burnt out! Contact Custodial if a lamp has been out for more than 2 weeks. Space well-lit without that bulb? Contact us to discuss delamping options.
