Use dimmer switches or three-way bulbs
Bulbs that can be turned down save energy.
Dimmer switches can be used with either incandescent or compact fluorescent lamps. Although CFLs remain more expensive, they are far more energy efficient than conventional incandescent bulbs. Three-way incandescent bulbs and CFLs also are available. Many CFLs are not designed to operate on dimmers and may even become fire hazards if they are. Halogen lamps must be periodically run at full power to avoid shortening lamp life.
