This is a problem that I had to solve on the show I currently have up. We have two chandaliers in the show with 10 3w flicker lamps per chandalier. I have them patched into CD80 2.4k portable dimmers. When there is no signal being sent to the dimmer 1 or 2 lamps on the chandaliers would randomly flicker at any given time. What do you think the problem is and how did I solve it?
