LED stands for "light-emitting diodes." It's a technology that has been around for a while, but until recently there were few products that used LEDs in Christmas lights at a price that compared with traditional strands. With energy prices at record highs, many people may think twice before decking their halls with electricity draining Christmas lights. Energy-conscious consumers can now choose from a growing array of LED lights that use less than one-tenth the energy of traditional incandescent bulbs, making them the green/eco-friendly choice for holidaydecorating. Major retailers carry LED Christmas lights in a variety of styles and colors. There are a variety of holiday décor items that feature LED lights such as trees, wreaths and candles.
The lights are energy efficient, environmentally friendly products. They are available in an amazing array of colors, styles and sizes and the prices are comparable to conventional electrical lights. The White House has even chosen to light the national tree with LED lights this year.
LEDs use plastic lenses, instead of glass and
filaments, and are virtually unbreakable. Meaning they also could prevent one of the season's inevitable headaches: the search for that one faulty light that blows out the whole strand. Unlike incandescents, if a single LED goes out, it doesn't affect the others, and LEDs are much less likely to burn out: They can last about 200,000 hours while conventional bulbs last 1,000 to 2,000 hours. LEDs can be used indoors and outdoors, same as traditional lights, but they use just a fraction of the energy that conventional bulbs consume.
