Hey, sorry for the delayed response. I got the parts from various places...
I got the retrofit MH from aquabuys.com and the MH ballast from ballastwise.com I got the Nova Extreme X2 from OA and the LED's from OA as well.
Everything else I built or pulled from other things.
On the cooling front, I have fans pulling and pusing inside the fixture run by my RK2 to coincide with the MH running. I also have a bank of fans running on the sump connected to the RK2 as well for when the tank temp goes up.
