Matt, I like the HQI foot print but I don't think I can add them to my canopy. The price is way cheaper to DIY it then to buy a 48" fixture retro fit. I can get 2 x 250 watt aro ballast and two 20,000 XM MH bulb with mogals and reflectors for 2 lights for $450. The aro ballast has a 3 year warranty. If anyone one knows of another place please let me know. The stand I am using now would need to be changed out unless I painted everything black but don't think the better half would like that idea.
