London in mid-January can be a dark, gloomy city – but not this year. For four nights, the capital's dark streets are being lit up for Lumiere London, a festival of lights. Colourful projections and light sculptures are illuminating 30 locations across the city including Mayfair, Piccadilly and Regent Street, Trafalgar Square, Westminster and King's Cross. The free outdoor light festival is produced by Artichoke and supported by the Mayor of London.
