Chauvet Sweeper LED Effect Lights
The Sweeper LED features six 3W, tri-colored LEDs and can be used together, working in master/slave mode.
The Sweeper LED's six pods of tri-coloured LEDs are contained in a single casing which sweep round beams of colour across the floor.
Each pod is designed to be individually controlled for color chases, sequences and effect combinations. Another feature can be achieved in master/slave mode. The master and slaved units can run as mirror images of each other. In other words, you can run pod six to pod one, then pod one to pod six and invert your show, according to Chauvet.
