Trafalgar Square, London. 23 January 2012. 6.51am. A spectacular sun created by art collective Greyworld as part of Tropicana's Brighter Mornings campaign brightens up Trafalgar Square.
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.
