Lighting uses 12 to 15 percent of the electricity consumed in a home. Suggested ways to economize on electricity bills with lighting are:
Turn lights off when you don''''t need them.
Use dimmers to save energy.
Use photoelectric cells or timers to turn outdoor lighting on and off automatically.
Use the more efficient reflector bulbs, especially for task and accent lighting. (Example: a 50W "R" bulb can put as much light on an object as a 100W "A" bulb.)
Use energy-saving fluorescents wherever possible. They give more lumens-per-watt (more light from the electricity consumed) than incandescents. New compact fluorescents produce light that is similar in color to that of incandescents, making them an excellent choice for residential use. They are now available in styles that can accommodate a wide variety of decorative and functional fixtures.
