As to lamps; heat lamps can be used on the screen of tanks, but not really with tubs. They can boost the ambient tempature and provide a hotspot if done right. However they do kill the humidty. Coupled with the fact tanks are already hard to maintain humidity in, it can be hard to sork with. And you don't want a light on 24/7 because it will stress out the BP and hurt its eyes.

If going with an overhead heat source though, a ceramic head emitter is generally better, as it puts out heat but not light. Unfortunately it still dries out the enclosure, so you will have to work extra hard to maintain humidity (misting multiple times a day, cover the screen top, bigger water bowl, get a humidifier for the room etc)


I have my BP in a tub and use a space heater to keep my room at 70f, and also use a heat pad. I'm not a huge fan of the tempature but I will sacrifice my comfort for my snake haha.
