55,000 LED Lights

  Aglowing cathedral like structure — dubbed the Luminarie De Cagna, was display at the 2012 Light Festival in Ghent, Belgium. "Soaring above the street at 91 feet high and using 55,000 LEDs to light up the night sky. The canopies and columns are created out of wood and the lights, and despite the jaw dropping light and color, the whole shebang only uses 20 kilowatts per hour of energy."
