Dimmers Introduction One of the best ways to save on lighting bills is to reduce the number of hours the lights are on. Even if you are leaving a room for just a few minutes, turn the lights off. You can also use light controls to reduce light usage. Occupancy sensors Occupancy sensors turn lights off automatically when you leave a room.
Most occupancy sensors operate by sensing heat or motion.
Motion sensors Outdoor security lights with motion sensors save energy and discourage intruders. Closets and cabinets equipped with switches turn the lights on when the door is opened and turn the lights off when the door is closed. Dimmers Dimmers reduce light levels and energy use for incandescent lights and some fluorescent tubes. The table below describes dimmer usage for different types of lights.
