Compact Fluorescent Lamps

Compact fluorescent lamps (CFLs) are a quick, easy replacement for typical screw-base incandescent lamps. CFLs use about one-third as much energy as incandescent bulbs to deliver the same amount of light, and they last about ten times as long. They also compete, as energy-efficient retrofits, with advanced halogen bulbs and LEDs. Higher-wattage CFLs can also replace linear fluorescent or metal halide lamps in some applications.
