I use LED source fours with cyc adaptors to light our hard cyc. Because I work in an old facility that is not wired for DMX we set them up with wireless DMX, specifically a ColorSource Relay Transmitter and Receiver. Most of the time they work great, but occasionally, usually at the end of a long day or mid-show after a couple hours of rehearsal they will randomly blink off and on. Initially I was wondering if there may have been an overheating issue, but that seems unlikely. Someone else suggested that the wireless DMX may not be robust enough and it is what is overheating or getting tired. Thoughts?
