The show i am providing lighting for calls for 6 LB Par Hex fixtures from Blizzard Lighting for color above the stage. I am controlling them all separately on an ETC Colorsource console. When I run the rainbow effect with any speed and a fan of about 30, some of the lights will flicker off quickly and on, then continue with their pattern. I am controlling these lights through wireless dmx but i have tried running a cable to them and that has not fixed the problem. Any help would be appreciated. The show starts Thursday, August 17th.
