Last night saw the iconic BT Tower turned into a giant lightsaber to help plug the new ‘Star Wars’ Blu-ray boxset. The ‘Star Wars’ spectacle was created using state of the art lighting that projected a shaft of light 200m into the air from the 189m high tower. More than sixty 4,500W lights, standing at 1.3m high and weighing 124kg combined to produce a staggering parallel blue ray of light (see what they did there?) that could be seen across the capital.
