Hey all ... I just purchased four of these new LED fixtures and I'm in the process of writing a complete evaluation which should be online later this week. All I can say thus far is that four on a T-bar as color fill has been awesome. I do need to put diffusion screens on them as looking back into the lights from the dance floor, these things are real "eyeball burners." Each fixture has twelve 10W quad-colored LEDs. I'm operating them in 4-channel dmx mode as I have no need for strobing capabilities which I'm sure would be very irritating. I opted for the RGBW version as opposed to the RGBA because I felt that adding white to most colors offered a better mix for pastels. To date, these appear to be the biggest bang for your buck in a flat/slim par format fixture and they are definitely plenty bright. I'll keep you posted later in the week.
