Here's an interesting combo I found in the downtown Montréal area. I think they are both 200W HPS, since I remember seeing a large number of 200W HPS fixtures in that area.
Well you THINK it's an OVZ! From that angle they both look very similar, none of us can precisely know which one it is.
MY guess is that it's an R37 because I remember that I saw many R37s in that area, but not a single OVZ. That's my guess and I am NOT 100% sure of it, that's just a guess.
