Hey miffspliff, looks much better :thumbsup:

As long as you keep temps at 85F or less in the shade then you're OK, 75F would be better of course.

I didn't see that reflector before so I'll take back what I said earlier about mounting the light differently. As for cooling the light, I don't really know if they make any kinds of cooltubes or hooded reflectors for those lights.

What the Kelvin rating for that light? From here it looks like a veg light (6500K), are you looking into an HPS (2200K-2700K) for flowering?
