There was a guy on RC in Albquerque that was making some relative inexpensive LED fixtures and/or selling the part for DIY. They were not just very big units.
Having owned one of these Commerical "overpriced" units the key if you are going to do this is the power supply. Make sure that you have output to spare after driving the LED's or you are going to be going thru powersupplies. Remember, you are going to be running this thing 24/7, with about 10-12 hours at full power. The overpriced makers have seen the light, so to speak, and have adjusted how the fixture draws its power and splits up the load accordingly. (a $290 Dollar upgrade)
No, not every LED is the same. You are going to need high power LED's at present two choices, Philips (PFO) and Seoul LED (AI). Cree uses both and both PFO & AI use Cree. The AI fixture uses three lights to a puck 2 whites and 1 blue. You also need some Cyan lights within the array or you are going to have color problems (PFO first fixtures).
Good luck to anyone who makes one, but if it was me and I was going to do it, I would get hold of the guy in Albquerque and get the parts from him along with the instructions. I looked at the MI reefer one, I am not so sure about the driver.
