The Rockefeller Center Christmas Tree is a world-wide symbol of the holidays in New York City. The tree, traditionally a Norway Spruce, is illuminated by 30,000 environmentally friendly LED lights on five miles of wire, and crowned by a Swarovski crystal star. Tens of thousands crowd the sidewalks for the event and hundreds of millions watch the Christmas Tree Lighting Ceremony broadcast live across the globe.
