I have a reefbreeders value fixture on half my 90G with full colors, and an equivalent DIY rapidled system on the other half. The rapid is def brighter, but the reefbreeder is awesome. I run mine at 50% whites and around 70% blues, about 6"s off the water, with them running about 10 hours a day. The rapid does a sunrise and sunset effect about 2 hours ramping up and down. I've had great growth with all my corals, including SPS, clams, LPS and softies, although ALOT of stuff bleaches near the top, so I keep most stuff lower.
I'd be patient and order from Logan at reefbreeders, ordering from china on ebay has bit alot of people in the butt when something arrived damaged/not working right;)
