Energy STAR and LED’s (light-emitting diodes) use 75 to 90 percent less energy than traditional lights, producing fewer gas emissions, and may last up to three years or up to 200,000 hours. You’ll save even more cash if you equip your lights with automatic timers since there’s no point in having them lit during the day. LED’s are water and weather resistant and are perfect for indoor or outdoor use. Find them at www.christmaslightsetc.com.
Also consider that battery operated LED Christmas lights can operate for 100’s of hours on a few AA batteries. Find at www.holidayleds.com.
Lose the hassle of having to find an electrical outlet or recharging your batteries and try solar holiday lights. These lights will do the trick just as long as you place the solar panel in direct sunlight. They will turn on automatically when the sun goes down! Silicon Solar, www.siliconsolar.com even carries traditional looking icicle lights. How fun is that!
