Its REALLY frustrating with the ph crap....hopefully the new meter will solve my problems with it.

The reflector is actually the one I used for my 1kw light until I got my cool tube. There's glass at the bottom of the reflector so the little fan is actually pulling the air through the vents on the other side and straight accross.

The 400w really has very little heat compared to the 1k. What lighting do you have Opie?
