What is a CFL?

A compact fluorescent light bulb (CFL) is made to be used in the same manner that incandescent light bulbs traditionally have been used. CFLs are specially designed to produce a warm, even light, while using up to 75 percent less energy than incandescents. They produce the same amount of light and last up to 10 times longer. You can use them in any light fixture in your home. There are many styles to choose from. 

ENERGY STAR® qualified lighting products offer extra safety and convenience features. Since CFLs generate about 75 percent less heat than standard incandescent lighting, they are cooler to the touch and reduce household cooling costs.

If every American family replaced their five most frequently used lights, or the bulbs in them, with ENERGY STAR qualified CFLs, each home would save about $40 a year in energy costs, and together we'd save about $600 million each year in energy costs and prevent 9 billion pounds of greenhouse gases, equivalent to the emissions from about 800,000 cars. It's a quick and easy solution to lowering utility bills in addition to saving energy and protecting the environment. For more information on CFLs, please visit www.energystar.gov.
