Rhp

In an arboreal setup, I place my probe half-way down the backside of the cage. I bought my arboreal cage from PVC Cages, and they cut out a place just under the vent in the back wall for the probe. Only the probe sticks out of the wall, none of the cord, therefore it can not be moved. In terrestrial setups, I place the probe above the substrate, and secure it to the bottom and back wall with plastic clips / screws.

Part two.

The bulb.
This enclosure came with a fluorescent (FLD) fixture 18 inch installed. I turned off all the heaters the UTH and the RHP (no snake remember) and ran the bulb and after 24 hours it was 140º on the exterior surface of the plastic cover.

I have added a led tube of lights (deep blue) as well they run at 101º.

Setting the timer to cycle 12 on and 12 off for the white FLD and 12 off and 12 on for the LED I got the following results.
65ºF/73º/73º/78º
71ºF/74º/74º/82º
80º/78º/78º/83.5º

I take away from this that the FLD units heat the air not really surfaces. They are hard to control as they cannot be dimmed (only special bulbs and fixtures can) the control is just time. I have a number of set ups that run bulbs and just by changing the timing of the bulbs I have been able to regulate the ambient air temps.

For myself the hope that an RHP would help to regulate the cool side and ambient air temps is busted. The rhp although a great tool does not alter air temps in any substantial way. The use of a light fixture goes a long way to control air temps. I have discovered a new product that claims to be a convection heater. Will heat air and be able to be controlled by a thermostat? I don't know yet I hope to get one soon to play with.

The simple solution of this problem is just heat the room. I know this is the easy answer. I like a few here don't want to heat my office (bedroom living space) to 80º all the time. I have a draughty old place and the cost of running such a heater is very high. Perhaps my tinkering (I already have this solved I am just continuing to search for alternatives out of pure curiosity) will help someone else down the road.

Cool little flash thing of radiation (rhp), conduction (UTH) and convection (CHE).

I tried a surface mount like you describe I simulated a snake with (don't laugh) a rubber dollar store snake and the back of that hit 97º on the cool side I decided that the probe placed where a snake could get between it and the heater not to be a good idea. RHPs seem to be perfectly suited to arboreal set ups until some here spoke of using them to control low terrestrial set ups I have never even thought of using one.

Oh the test cage is 24x24x12...
