There's no question that Americans love their Christmas lights. Last year, Home Depot sold enough strands to circle the Earth 1.6 times. If you're worried about all the energy those lights will consume, you may want to look into LED lights. Here's a primer on the difference:
Incandescent bulbs use an electrically charged filament that burns white-hot, producing light. However, the heat has a tendency to burn out or break the glass bulb and must be replaced.
LEDs are a form of semiconductor technology, which uses light-emitting diodes to produce light. They are made in the same shapes and varieties as standard incandescent lights, but are more durable because the lamp is made of solid plastic, not glass. Since 2002, manufacturers have made LED lights bigger, brighter and with more colors.
According to the Department of Energy, if every household and business in the United States switched to LED holiday lights, the savings would be equivalent to the annual electricity consumption of almost 500,000 households.
Advantages of LEDs over conventional holiday lights include:
- In 2007, running incandescent lights on a 6-foot Christmas tree for 12 hours per day for 40 days costs $23.95 in electricity. LEDs cost 54 cents. Click here to calculate your own energy savings by using LEDs.
- LEDs are low voltage and run cooler than incandescent bulbs so there is no risk of electric shock or fire. In the United States about 300 fires each year involve Christmas trees.
- LED holiday lights last longer with a life span of about 20,000 hours (40 holiday seasons) 30 times longer than incandescents.
Also, LEDs produce light of a given color without requiring a filter, and they produce focused light without a reflector. Because LED holiday lights use less power, you can safely connect multiple string lamps end-to-end without overloading the wall socket.
