Choose compact fluorescent light bulbs.
Replace old-fashioned incandescent bulbs with compact fluorescent light bulbs (CFLs), which use 75 percent less energy and last ten time longer. A typical seventy-five watt incandescent bulb can be replaced by a twenty watt CFL.
Take some simple precautions when using CFLs. Don't use them in closed fixtures. Do not use with dimmers—this creates a fire hazard. (There are some new CFLs available that can be used on dimmers, but they are hard to find. This must be stated on the package.) Check the packages for safety warnings and compatibility with different fixtures. At the end of their operating lives, CFLs should be disposed of properly as they contain mercury. To find out how to safely dispose of CFLs, contact your municipality.
