Why is my beardie always standing?

I don't think he's trying to reach the heat lamp or the UVB. I have both of those lights sitting right on top of his enclosure screen. His basking spot on top of his branch is like 4 inches below the heat lamp. His UVB sits right next to the heat lamp.

I have the Reptisun 10.0 UVB and the 100W Repti Basking Spot Lamp. I used to have a heat rock but heard those can burn babies' bellies, so I returned it and got a ceramic heat emitter made for a 40 gallon tank like I have. When his UVB and heat lamp go off at night, the ceramic heat emitter turns on so his enclosure doesn't get too cold. It has a dimmer on it so that I can control how warm it gets. My house temp stays pretty low, at around 63 degrees, so that's why I have the ceramic heat emitter.

His basking spot is where the thermometer says 115. I don't think it's actually 115, as I heard that those stick-on thermometers can be inaccurate. I need to buy a temp gun or a thermometer with a probe to get more accurate temperatures, but I haven't gotten the time to purchase one.

If the temperature is a part of the problem, I will know once I am able to get more accurate readings, but for now I feel like it is warm enough (especially with the CHE) that he isn't trying to reach the lights. I can't really think of any other reason why he always resorts to that spot to stand (and fall asleep!)
