The Chauvet COLORPalette LED Color Bank System is a new 6- to 27-Channel DMX system with amazingly cool effects. We sell in sets of two because that's where this light stands out. Try using 3-6 sets (6-12 Lights) for an even more remarkable stage presence. COLORPalette has blackout, static, dimmer, and strobe effects as well as advanced RGB Color mixing, color fade and automatic programs with built-in sound activated modes. Your stage will not be sorry when you purchase these!
