Tate Blackouts

Olafur Eliasson, best known for 2003's Turbine Hall installation The Weather Project, has been working on a way to bring cheap, safe light to those living off the grid. The resulting solar-powered Little Sun lamps will be on display on the third floor (together with information on solar power and the global energy challenge) until September 23. To encourage visitors to engage with the lamps, Tate has organised Blackout nights: two hours of darkness in which visitors will be armed only with a Little Sun lamp as they tour art in the Tate's surrealism collection.
