The Lightwall Tunnel, a 90m-long pedestrian tunnel at London’s King’s Cross station, is lit with an integrated LED light wall. The interior, lined with repeating panels, contains 190 control-lable vertical pixels set behind 12mm toughened glass. To enable an effect of seamless lighting running the length of the tunnel, architectural lighting specialist- The Light Lab, installed LEDs behind the glass panels. The LED lightis themselves are capable of emanating the full RGB spec-trum and also a white light spectrum from 3.0K to 6.0K, creating a subtle and beautiful moving light show with no shadow lines.
