As for your question about power supply , they told us that they use some CE ,Rohs Power supply , for UL led driver and meanwell led drivers , price is different .That's what I have been told . I asked why not use the best one , they said the best one with more money , people always think their led grow lights are very expensive with meanwell ,UL led drivers . Any questions you want to know , go directly to them .First off, the A51 RW75 is $199 currently (you are looking at the old site). Second, that light you are pushing is 90x3w diodes but they are not driven that hard. They are probably running @ about 1.75w per light, if they are lucky and probably very inefficient. I notice there is no details from your links above. Not only that, the drivers are probably garbage. Just because you utilize CREE diodes does not mean you are utilizing quality drivers to go with them.
