Multi-Colored LEDs Offer Energy Savings for the Holidays
If you've been procrastinating on hanging up your holiday lights, we have good news: new LED (light-emitting diode) holiday lights are now available in a wider variety of colors and shapes! You may remember that as of last December, only red, green, and yellow bulbs were available, and the fashion-conscious among us probably found them to be, well, somewhat lacking in aesthetic appeal. This year's models offer a much wider range of choices, including two new colors-white and blue-and a variety of shapes, such as multi-faceted, mini-light, globe, and the good-old flame-tip shape. The bulbs use only one-tenth the electricity used by mini-lights, and one-hundredth the electricity used by traditional C-7 bulbs. In addition, they are very rugged, never get hot, last a long time, and are easy to maintain. And for those who like to cover a lot of distance with their lights, up to 20 strings of LED lights can be connected together without overloading a typical U.S. household's electrical circuit.
The Energy Ideas Clearinghouse recently updated last year's fact sheet on holiday lights with the latest information on the LED bulbs. The clearinghouse even found that LED lights will pay for themselves over five years of use. See the latest "Holiday Lights" fact sheet (PDF 135 KB). Download Acrobat Reader.
