For some reason it just dawned on me that I could use UTHs for my colubrids. I use heat lamps for them. The light bulb in my head finally started working on the subject.
Finally finding UTHs that I can trust helps too.

My questions for now:

1. Who uses UTHs for their colubrids?
2. Does anyone use supplemental lighting along with the UTH?
3. How are your ambient and cool side temps?
4. If your room isn't warm enough to keep ambient/cool side warm enough, how do you do so?

ty for any answers.
