check out migro you tube channel. theyre based in dublin. his current video on you tube is a comparison test of led lights they have the top 20 listed. im using the migro aray 240w + red in my 2x4 at the moment.
@Conn I watched that yesterday, great video. I've used his videos to help guide my purchasing decisions when moving from HPS to LED. I've been curious about his lights, cool that you have one in action.
