My boss bought a set of the 6.5" and 3.5". He ended up hard wiring them, and gave me the wireless kit. I used one of the kits for a week, and ended up har-wiring my lights. Not saying it isn't cool, just another rmote to keep track of, haha! I can't speak for ow bright the lights themselves are, as I haven't seen them in person, but he did say my Rigid Dually D2's blow them away.
