Be on the cutting edge with light-emitting diode, or LED holiday lights.

Each bulb with this new technology uses only 0.04 watts and is up to 90 percent more efficient than its incandescent counterpart. So a household burning 10 strands of lights for eight hours a day for a month at $0.0853 per kilowatt-hour would spend $127.67 for large, incandescent bulbs, $7.20 for traditional mini-lights, and just $0.72 for LEDs. These newer bulbs are sturdy, last up to 100,000 hours, or 20 years, and barely warm up, eliminating fire concerns.
