[3] Hosted in winter time, and free to attend, the festival typically comprises a number of light art-installations, as well as illuminating iconic buildings and locations.

75,000 people attended the four-day event in 2009, the central exhibit of which was Durham Cathedral illuminated with projected images from the Lindisfarne Gospels.

In 2013 the light show was taken to Derry in Northern Ireland where almost 180,000 people visited 17 separate art installations around the city, including illuminated sculptures placed around the Peace Bridge and projections on Austins department store.

In January 2016 the festival was brought to London for the first time, with light installations sited around Piccadilly, Grosvenor Square, and King's Cross.

For four days, over 50 works of art were on public display in King's Cross, Fitzrovia, Mayfair, West End, Westminster, Victoria, South Bank, and Waterloo.
