My band uses three of these to throw a red light on our 6x12 and 8x10 cabs for visual effect on stage.
So only standalone use, no dmx so can't comment on that.
There are enough colors available to find what we needed, the only thing I maybe wish it could do is dim the color, there is only one setting and that's full on. But for our use that's just fine.
Light output is very good while not get the blinding effect when you look right into it, unlike some other lights with the round spot style lights.
