This light chaser uses a simple, but very effective design. When music is playing, it switches in time with it. It is a mains powered unit, housed in a strong aluminium case. The four globes are switched on and off sequentially. The speed is controlled by an internal sound modulator, with a small microphone built in to detect the music. It measures 435(W) x 105(H) x 185(D)mm, includes a mounting bracket, and 800mm mains lead. It uses 240V 60W ES reflector lamps, and is supplied with a red, yellow, green, and blue globe.
