Compact fluorescent lamps come in a variety of shapes, sizes and colours. When selecting compact fluorescent lamps , remember that the greatest savings occur if used where lights are on for long periods of time.
Photocells turn lights off during daylight hours.
Occupancy and motion sensors turn lights on or off when someone enters or leaves a room, and are commonly used for security reasons outside the home to turn lights on when someone is in the yard. Helpful hints Convert incandescent bulbs to energy-efficient compact fluorescents. Turn off the lights when you leave the room. Keep light bulbs and fixtures clean. Use task lighting for close work, rather than lighting the entire room.
