Good luck with your setup man. Hope to see some spathes from you soon.
About the shop lights... how come you didn't get the ones with the polished reflectors? I got them and they work great. Though instead of running 1 fixture, I'm running 2.
I just grabbed cheap ones from home depot do they have ones with polished reflectors. I'm getting quotes on some custom tanks with front openings on them and plan on 4 bulbs over each if I go that route.
