I am mostly doing videography for classical music performances and I got two of these lights in addition to my tungsten lights. They are very quiet (the fan speed depends on the intensity of the light, but even on full intensity the fan noise is very low). The light output is really nice, wide and very even (no hotspot, no color separation), and with two of these you can get a nice color wash on a wall 10 m wide, 6 m high, if the light is 3-4 m from the wall. They can compete nicely with ambient light, so the room doesn't have to be completely dark, but bear in mind that it is not the strongest light around. I also used them as backlight for lighting the performers, and it looks great on camera. Amber and UV are a bit weak, but usable. Try mixing UV with amber, very interesting results. You can achieve great color rendering by mixing all the colors to a white light, you could even use it as a main light. It's that good. I did not observe any flickering, but buyer beware. Some of the cons: they are very large, bulky (although not very heavy), since they are indeed standard short PAR 64s. They have a wide beam so you won't get the light pillars with them. I measured the power consumption of individual channels and here are my findings: All zero (standby) is 2.5W. I measured all the channels at full and subtracted the 2.5W: Red @ full 20.8W, G 32.2W, B 32.2W, W 32.8W, A 14.5W, UV 27.6W, all @ full 160W. In conclusion, if you're on a tight budget but need a strong and quality light and don't care if it's bulky, buy this one. I got it less than a week ago, so I don't know how it will behave in the long run.
