I'll post pics tomorrow my camera is down now but I'll borrow one.

If I think a lamp will fix my problem I'll get a second thermostat.

I'm using a reptitemp 500r for the thermostat now to control my uth.

The 81 temp is being taken against the bottom of the tub above the substrate, the 94 as well but on the hot side. The 80 (77 when its down) is being taken by sticking a prod into the middle of the cage to measure the air inside the cage. I think that is what you mean by where am I taking my readings.

For now I've put 1/4 inch think foam board around the tub to help keep it warm, its holding the heat lots better now, the thermostat isn't turning on anymore, but I don't think its going to work completely, to test I opened my window and cooled my room down and it started to drop even with the insulation on.
