I bought the Chauvet 4-Bar and LOVE it. (
LINK).
PROS: The LED's are very bright, especially in the subdued lighting of a bar. Are they as bright as PAR cans? No, but in my situation I think PAR's would be TOO bright. The biggest benefit to me was the low power consumption...48 Watts! If I was to plug in conventional lighting at 400-600 watts, I would be blowing breakers for sure. They come with a very sturdy, velvet lined case & bag for the stand. I have used them on the road for several months now, and have had zero problems.
CONS: Expensive compared to conventional lighting ($399 List). I have read that the DMX interface is a bit "laggy". I don't use a lighting controller, so it's a moot point for me.
Overall, I am delighted and would buy them again. In fact I am saving up to buy a second unit.
