I'm working at a school. Some classrooms that have lets say 9-12 led fixtures. In some classrooms when dimming the lights, maybe one or 2 fixtures will either dim to a level that doesn't match the others or will appear to be off. I don't have the print in front of me but I have a suspicion most of these troubled fixtures are at the end of a daisy chain if that makes any sense. Does anyone have any ideas. I haven't tried any troubleshooting yet.
