The Chauvet 4Bar Light System is a great product for bands or DJs playing small clubs and events. It is easy to carry around, easy to set up, and easy to operate. It does multiple colors, chases, fades, sound activation, and is DMX controllable. However, this is not a heavy duty system suited for the band truck and roadies. The lights are plastic and need care in set up and transfer. Replacement parts are available from Chauvet for every part of this system from lights, stands, to controller. Two of these light bars will adequately cover a typical stage in a small club. They will add color and motion to your show.
