Great shimmer By Mike on 3/16/2014Mike would recommend this product to a friendI installed these to get a little more growth out of my corals. I had 20k lights before these so the color change was a little more bright (yellow) than what I was accustomed too. They look great and provide a lot of shimmer. It's to early to comment on the growth that they will provide.
excellent bulb so far. 3 weeks By mos90 on 8/23/2013mos90 would recommend this product to a friendi added this bulb to replace my 400w radiums. though i do like the radiums i wanted the outsides of my tank a little brighter and a little more white. so far the corals have responded well to the change. its too early to notice any growth changes.
i still kept 1 radium in the middle of three bulbs. they make great combo like.
