So the tour I'm working right now has about 80 of these, Ayrton 150 moduLED, built into the set under clear Lexan as footlights. They're great. One of the neatest features, is there are no buttons. Below each of the standard labels: Menu, enter, up, down; are photocells on the front of the fixture, for setting mode and address. I'm sure these are expensive units, but seem very well made and with very good output.
