I see you have a coil reptisun bulb for UVB, those will cause problems in your beardie and can harm their eyes. What you need is the reptisun 10.0 tube light mounted inside the tank so he can get to within 6-8 inches of his light. Also he needs a bright white basking bulb placed next to the UVB to keep his eyes from being harmed. With the wrong UVB they can become lethargic, have digestive problems, eye problems and calcium absorption problems along with D3 not being properly synthesized for the utilization of calcium. I am not sure if the power sun does both heat and UVB but if it does I would turn off the coil bulb..he does not need 2 uvb lights. I also agree about the temps and thermometer.
