Electric Lighting
Replace existing conventional incandescent light bulbs with Compact Fluorescent Lamps (CFLs). Initially, CFLs cost more than incandescent bulbs, but they last at least seven times longer and use less energy. The savings gained by using a CFL will quickly outweigh their higher initial cost.
Use “task lighting” wherever possible. For example, a low wattage bulb can be used to provide general lighting in a kitchen area where it is common to leave the light on for extended periods. However, counter-top lights can be used to provide brighter direct lighting in specific areas when required.
Use conventional fluorescent tubes in large areas or areas that require bright lighting for long hours. Look for fluorescent tubes with newer electronic ballast, as these are more efficient. For outdoor security, use security lights with motion sensors, photocells or timers. In this way lights will only be on when required.
Compact fluorescent lamps (CFLs) can be used with or without lamp fittings for indoor purposes but should be used in an enclosed lamp fitting for outdoor purposes. Fittings should be sufficiently large as CFLs are usually larger than conventional light bulbs.
