Wow! This has to be the easiest way to provide wash style stage lighting. With my band, we used to use the old fashioned Par cans system, heavy, bulky, time consuming to set up and, of course they produced a huge amount of heat which is, naturally, not a good thing on stage. The LED parbar III is a different thing altogether. Light, all in one piece, instant set up, built in control (DMX link inc.) and as bright as any old style Parcan. And no heat!! A very good buy. The case feels a little flimsy and I wonder how long it will last but, otherwise, very pleased.
