One more question--!
I'm likely going to forego the flex-watt heat tape and just stick with a RBI RHP. I'll add a UTH as a hot spot if needed in the winter if the RHP alone is not sufficient (although from the looks of it, it looks like it should be fine). For asthetics, I would like to ask AP to install the fluorescent lighting. A Google search of the setup show that they place the bulb towards the back of the enclosure. Is that true to your guys' experience? How far away should I place the RHP from the fluorescent bulbs? I know they don't get very hot, but I would also like to avoid damage to either the RHP or bulb in either case.
