I used two of these lights at a small DJ/music event this past weekend, along with a few other effect lights. They worked great and were plenty of light to cover the small dance floor. I didn't play with the built-in programs or sound-active mode, but basic RGBW control and strobe worked great. There is a small bit of fan noise noticeable at close range in total silence, which is not an issue during an event. The UV light is ok, but it does not react as well as another UV LED light that I have to white fabrics and plastics. Note that the 32-bit dimmer mode is enabled by default, and should be disabled for events where responsiveness is desired.
