1 WTC is 1,776 feet tall, has 3 million square feet of office space NEW YORK, Nov. 8 (UPI) -- The beacon atop the new World Trade Center was lit for the first time Friday, 1,776 feet above the streets of New York. The beacon contains 288 50-watt LED modules that produce 288,000 lumens of light, making it visible for as far as 50 miles on a clear night, the Port Authority of New York and New Jersey said in a release. The spire on which the beacon is fixed will serve as a state-of-the-art broadcast facility, to be operated by The Durst Organization, that will provide "unparalleled transmission services for the region's broadcast outlets," the release said. The spire was completed May 10, 2013, bringing One World Trade Center to the iconic height of 1,776 feet. The skyscraper boasts 3 million square feet of office space, half of which already has been leased.
