Lighting controls

Adding different lighting controls to your lamps and overhead fixtures can help you save energy by adding light only when and where you need it.

Most of these controls are fairly easy to install yourself if you're comfortable with basic wiring guidelines.

• Dimmer switches are great for "mood lighting" - and they can help you save energy and extend bulb life. Some models combine a dimmer slide and an on/off switch, allowing you to set the light to the desired level once, instead of sliding it up and down every time.
• Motion sensors, primarily used for outdoor security lights, are also great indoors, especially in stairwells, closets and utility rooms. Instead of fumbling for a light switch while your hands are full with laundry or groceries, a motion-sensing light switch will automatically turn the light on for you.
• Occupancy sensors, used in many businesses, rely on body heat instead of motion. Motion sensors will turn off the light if no motion is detected; occupancy sensors will keep the lights on if the temperature in the room remains constant.
• Photocells turn react to changing outdoor light levels, making them perfect for lamp posts and other exterior lighting. When the sun goes down, the lights come on; when the sun comes up, the lights go off.
• Timers can help make your home look lived-in while you're away on vacation. You can find models with seven-day settings, allowing for different timings every day of the week.
