This past holiday season saw a large trend of holiday lighting with light-emitting diodes (LEDs), which use one-fourth the energy of incandescent bulbs and, in this case, are actually brighter, meaning holiday decorators can use less lights to brighten up the same amount of space. "LEDs are substantially more efficient than incandescent lights," said Tom Reddoch of the Electric Power Research Institute. According to Reddoch, a 50-light string of LEDs uses 2 watts of power, and the same size string of mini incandescent bulbs uses 11.5 watts. "Because LEDs are brighter, fewer strings could be required," he said.
