Save Energy with Holiday LEDs

If you enjoy holiday lights in or on your home, save money and protect the environment by switching to LED (light-emitting diode) holiday lights.

LEDs employ semiconductor technology to convert electricity into light directly, resulting in significant energy savings. An LED uses approximately 0.04 watt of electricity, compared with 0.45 watt for a mini incandescent light bulb and 7 watts for a C-7 incandescent bulb.

According to the Union of Concerned Scientists, LEDs provide several other benefits as well:
  • Safety—LEDs stay cool to the touch, posing less of a fire hazard compared with incandescent lights. In addition, their low energy consumption allows you to connect up to 25 strands of lights end to end without overloading a circuit.

  • Durability—The small size and solid construction of LED bulbs make them less likely to break.

  • Long Life—LED bulbs can last up to 100,000 hours or more, which is equivalent to more than 10 years of continuous indoor use. If a single bulb in an LED strand does happen to fail, the remaining bulbs will continue to work.
From Green Tips:
While they have a higher purchase price (they cost about two to three times more than incandescent lights), LED holiday lights quickly pay for themselves through energy savings. Using the national average residential rate of 11.06 cents per kilowatt-hour, it costs only 32 cents to use 300 LED lights for five hours per day for 45 days. In comparison, using incandescent mini lights or C-7 lights for the same amount of time would cost $3.36 and $52.25, respectively...
