The Trafalgar Sun is a new public art installation in central London. The Trafalgar Sun, which took six months to create, is 30,000 times bigger than a football, has a surface area of 200m2 and weighs over 2,500kgs. Its internal light source produces 4-million lumens of light, the equivalent of 60,000 light bulbs, making the artwork visible from space.
