The Rockefeller Center Christmas tree is going "greener" -- with energy-saving lights replacing old-fashioned bulbs on the towering evergreen this year.

The 84-foot-tall Norway spruce will be covered with 30,000 multicolored light-emitting diodes, or LEDs, strung on five miles of wire.

Using the energy-efficient LEDs to replace incandescent bulbs will reduce the display's electricity consumption from 3,510 to 1,297 kilowatt hours per day. The daily savings is equal to the amount of electricity consumed by a typical 2,000-square-foot house in a month.

After the official tree lighting ceremony on November 28, the Christmas tree will be illuminated from 5:30 a.m. to 11:30 p.m. most days through the first week of January.
