Ditch all of it and get a CHE, or even multiple CHEs. Bulbs dry the air out, and UTHs are unnecessary. The whole goal of heating is to get the reptiles core body temp to around 82-83 degrees. People clutch to the idea of a UTH because it is just commonplace and works, yet doesnt mean that is necessary. We are now finding that heat from RHPs and CHEs is tolerated much better than from other heating devices, and actually is shown to have therapeutic benefits. You can fine tune your CHE with a dimmer, or thermostat to achieve any temperatures you want. Personally I would just find the best combo of CHEs, or a RHP that can keep your temperature at about 84 degrees and thats it.
