In the latest move, New York City’s Rockefeller Center Christmas tree, illuminated last night, shines not with old-style incandescent bulbs but with 30,000 electricity-sipping light-emitting diodes, or L.E.D.’s, powered in part with solar panels. (And the tree was even cut with a hand saw, the city says.)
And you, what type of lights are you putting up this year? A 100-light string of multi-colored LED bulbs uses just 8 watts, compared to 36 watts for mini lamps and 500 for incandescent Christmas lights (C-7 bulbs).
