Thanks for posting the pics. As far as LED panel arrays go, that's probably one of the better ones I've seen. Most of them like that are 225 LEDs and 14W so they're all way under powered. Next time I see someone posting a link to one of those, I'll point them to this one.
For non-forced cooling stock fixtures, this is a pretty good one. I think the wattage is a bit on the low side overall, but that is made up by the use of bandwidth, it's about a 3.5:1 red:blue ratio which is probably a little high on the blue, and interstingly enough, this is a "B" band fixture. It uses 630nm Reds and 460nm Blues. Most "grow" lights use 660/460 which is a mix of A and B. So congrats, you're the first one I can recall using this bandwidth!
Going by the new sizing and light guidelines, I don't think many people would be in the market to use this light though because not many have a need for a 12x12 screen (12 cubes/day) and if you were feeding that much, it would probably overpower the screen, just because there's not quite enough intensity. This is a very good example however of the usefulness of LED lighting on a screen that is too large for the feeding (I'm assuming here that you're not feeding 10 cubes/day or more). CFL and T5HO screens that are too large compared to feeding tend to grow yellow rubbery algae like mine currently is. So far, all the LED builds I've seen tend not to grow the yellow algae at all, which I find very interesting.
Thanks for posting that info!!
