I forgot to put that I have the lamp on a digital timer (on 12h/off 12h). I read on several care sheets that although BPs don't require UV rays since they are nocturnal, it helps to have defined artificial day/night periods to simulate their natural habitat. The ambient temps are in the low 80s at night but if this drops during the winter months I'll probably end up changing to an IR bulb and hooking it up to another Herpstat with a night mode.
Edit: On second thought, I might switch to a CHE anyways. The light coming in the room windows should be sufficient to distinguish day from night.
