    We're mostly a legacy lighting stage but are running a couple of LED Cannon washes. On a couple of occasions after turning off the console (ETC Element 2) . I've noticed a short time later one of them has come on Red! All channels had been zeroed before turning off. Turning the board of and off again, or pulling the LEDs power cord for a few seconds turns the rogue light off. Any ideas about this are welcomed.

    Do you have dimmers?
    Not necessarily the most ideal power source for LEDs, but it's something I've done before.

    You could power the LEDs through dimmers, that way when you want to "shut down" you can literally just turn those dimmers off. I would also suggest adjusting the voltage and curve outputs on those dimmers.

    If not, it honestly isn't a bad idea to unplug your fixtures when you're not going to be using them. Just add that to your shut down checklist I guess?

    DMX ghost. Nothing you can do besides what you are doing.

    Unless the manufacturer has certified that the LEDs are dimmer safe, I really wouldn't power them through dimmers. The SMPSU in the lanterns really won't like it. Just read recently about a theater in Aus where a group hired it and plugged the LED movers into dimmed rather than power and damaged a whole load of them, necessitating them going back to the manufacturer for repair.
