Energy-Efficient Lighting

Like most aspects of home improvement and home building, the lighting industry has developed its own language. Here are a few of the industry's most often used terms:

• Watts are standard units of measure in electricity. One watt is equal to 1/746 horsepower.



• Lumens are the standard measure of light produced by a bulb. Standard 100-watt bulbs produce about 1600 lumens.



• Incandescent light bulbs have a filament that's heated to the point of glowing. The glowing filament produces the bulb's light.



• Fluorescent bulbs or tubes are filled with mercury vapor that emits ultraviolet light when electricity is applied. The bulbs/tubes have a coating inside that turns the ultraviolet rays into visible light.

We all remember a parent complaining about having every light in the house on. If you're paying electricity bills, you've probably said it at least once. Here are a few ways to take the edge off of those high energy costs:

Track lights make good task lighting.

• Compact fluorescent light bulbs use about 1/4 the energy of regular incandescent bulbs to produce the same number or more lumens. They also last about ten times longer than regular bulbs. Some compact fluorescents are warranted for eight years. Compact fluorescents cost a bit more initially, but the long-term savings more than offset the initial difference in price. A compact fluorescent that gives the same amount of light as a 100-watt regular bulb can save you over $80 over the life of the bulb.



• Task lighting concentrates the light where you need it. With task lighting you aren't wasting energy casting light in spaces where it isn't needed. You also aren't annoying others in the area with an intrusively bright light. When you use task lighting, you can use a lower watt bulb to accomplish the desired result.



• Three way bulbs in touch lamps or regular three way lamps are also good ways to save energy on interior lighting. The bulb allows you to use only as much light as needed, but gives you the option of brighter light when required.

Motion detectors provide light when needed.

Lighting isn't limited to the inside of your home. Most homes have at least a light at the front door and some way to illuminate the walkway to the house.

• Motion detectors are great energy saving devices for your exterior needs. They come on automatically and stay on as long as motion is detected in the area. With motion detectors there is no need to leave a light burning while you're out. It will come on automatically to light your way when you return home.



• Low voltage lighting can be used to light walkways with significantly less power than regular incandescent bulbs. One 60-watt string of light can illuminate up to 100' of walkway. You can also install timers and sensors that turn the lights on at dusk and shut them off after a specific time.



• Solar exterior lights charge all day in the sunlight, and then come on as darkness falls. Solar lights are slightly more expensive than regular low voltage lights, but they don't require any electricity or cords. You can place solar lights anyplace that receives sunlight.

Take a walk around the house and see where you can make a change to save some change. It's not just money or energy you're saving. It's also the environment. Invest in a few light bulbs or fixtures and consider it an investment in the future as well.

Tips and Notes ENERGY STAR lighting uses about 75% less energy than a standard incandescent bulb and lasts up to 10 times longer, while providing the same high quality light. The energy efficiency performance of ENERGY STAR lighting also means savings of at least $25 in energy costs over the life of each ENERGY STAR bulb that replaces an incandescent bulb. Consider purchasing ENERGY STAR lighting to help save money on utility bills through superior designs that require less money and less energy to keep your home cool and bright!
