check out reefbreeders photon series. it will be my next purchase of lights, and i know a couple of people that already own them and LOVE LOVE LOVE them. plus they are very reasonably priced.
Definitely agree with above posts here. For the money go with tried and true/trusted US sellers and Sponsors here. My choices in order would be Reef Radiance, Reef LED's and ReefBreeders all depending on what application is.
Look at OceanRevive's OR-IT2040. More leds, lower cost and built-in controller. I've had one running for 14 months 24/7 with no issues at all!
Oh, and they are a sponsor here at R2R: Ocean Revive LED
