January 23rd. One of the most depressing days of the year.

Its a Monday. Christmas is long gone, but the bills are coming in. Another week until pay day. And there is little daylight.

To change things for the better, greyworld created a special Sun, which spread its dawn light throughout Trafalgar Square for one day only.

Weighing 2.5 tons, and using 210,000 watts of power, the Sun illuminated the Square to give Londoners a brighter start.

The project was commissioned by Tropicana. Below are two videos that show us creating the Trafalgar Sun.
