I found these LEDs on ebay for a decent price the brand is REEFCHOICE, yes I understand ebay tends to be poor products but I see that this fixture is made with cree LEDs and ive been emailing back and forth with the maker to find out more info and just about the only thing else i need to know is what kind of drivers it uses the only thing i dont like is that it isnt dimmable but neither is a MH bulb I said to them: Hey I am interested in your fixtures however I was wondering if I could get better specifications like what kind of drivers are used, the size of the fans, do the fans have speed controls, is there a dimmer for both blue and white, are both blue and white LEDs cree, what kind of coverage will a light like this have in surface area, what would you recommend for a 55 gallon mixed reef, is there a hanging kit included or other hardware, etc? I would definitely be interested in buying a fixture or so if you could give me as much information on this fixture as possible...the more information you could offer the easier it would be for me to make a choice. Thanks for your time and for the information.
