Last night, London Mayor Boris Johnson flipped a switch and brought to a rousing conclusion six month's work on an energy-efficient LED array on London's landmark Tower Bridge to celebrate the Queen's Jubilee.
The array, which includes 6,500 feet of energy-efficient LED linear lights, 1,800 LED lamps, and 1,000 junction boxes with 16,500 feet of cable, will shine "diamond" white throughout this weekend's royal celebration.
The new lighting system, which is using GE architectural LED systems, will remain in place for the next 25 years. It replaces a quarter of a century old legacy system and will cut the landmark’s energy consumptions by 40 percent. The French firm Citelum, whose lighting designs illuminated the Eiffel Tower and the Notre Dame cathedral in Paris, and the Valley of the Kings in Egypt, built the lighting set up.
The GE LED technology lets Citelum blend many shades of colors of variable intensity. The lights have been “heat formed” to fit a variety of architectural needs and enhance the Victorian gothic turrets, stone towers, and walkways that make this the 117-year old bridge one of the world’s most recognizable sights.
GE, a sponsor of the 2012 London Olympics, partnered with EDF Energy on the project. During the 45 days of the 2012 Olympic and Paralympic Games held in the British capital this summer, the bridge will sport giant Olympic rings and Paralympic agitos symbols.
