Tufts faculty and staff can exchange their office incandescent light bulbs for one free Compact Fluorescent Light Bulb.

Why Do It?
Replacing energy-hogging incandescents with energy-saving fluorescents is a simple, effective way to slow the rate of global climate change while saving Tufts money. There are lots of reasons this is a good idea.
It’s Good for the Environment.
Most electricity used for lighting is generated by coal and oil power plants (more about electricity). These power plants pollute the atmosphere and emit CO2, which causes global climate change. Each CFL that replaces an incandescent bulb can cut CO2 emissions by 1,300 pounds over its lifetime, saving the energy equivalent of 50 to 60 gallons of oil. In addition, for every CFL used, eight fewer incandescent lightbulbs end up in landfills.
It’s Economical.
TIE will provide you with the CFL you need for free! One CFL uses 25% of the energy of an incandescent bulb and lasts nine times as long, or up to 7 years. This savings averages $32 per bulb from lower electricity bills and less frequent replacement costs.
It’s Efficient.
Incandescent bulbs waste 90 percent of their energy generating heat. CFLs use only one quarter as much energy to produce the same light. The “fuel” efficiency of a CFL is like replacing a car that gets 20 miles per gallon with one that gets 100 miles per gallon.
It’s Easy.
CFLs come in more sizes and shapes than traditional lightbulbs, and it’s easy to find one that works perfectly for your lamp. Older fluorescent bulbs had a reputation for bad lighting quality and noise. Today’s CFLs use a much better mix of phosphors (the white powder coating the bulb inside), and have color qualities much closer to incandescent bulbs. New CFL technology also has eliminated humming and flickering.
Important things to know about CFLs:
1. CFLs reach their fullest brightness when they have been on for 1-2 minutes.
2. CFLs are less bright in cold environments (e.g. outside).
3. You cannot use a regular CFL in a dimmable or three-way fixture. You have to buy a dimmable/three way CFL. Regular CFLs will not work with a dimmable switch.
4. CFLs contain small amounts of mercury. Do not dispose of them in your trash. Call your municipality to find out how to dispose of them. (At Tufts, e-mail recycle@tufts.edu)
5. Not all brands are of equal quality. A CFL should not flicker. It should last a very long time. If your CFL flickers or burns out quickly, do not hesitate to return it. Also, try different brands to find the brand you like best.
