2012 marks the 60th year of our Queen Elizabeth II's reign — her diamond anniversary as monarch of the British people. Ahead of the celebration for this momentous milestone (as well as the 2012 Olympic Summer Games) crews wreathed London's 117-year-old Tower Bridge in thousands of LED lights. And last night, Boris Johnson flipped the switch.
In all, crews spent six months designing and installing the new system. They laid almost 2,000m of LED linear lights, 1,800 LED lamps, and 1,000 junction boxes running over 5,000m of cable. Designed by the French firm Citelum, the installations is expected to weather London's weather for the next 25 years with a 40 per cent energy saving over the previous lighting rig. [GE]
The bridge will remain all-white like this through the Queen's Diamond Jubilee.
