Yep! I finally got a setup going that puts the cool side at 81 with a gradual rise up to around 90-93. And I ordered the RHP along with the cage, so it arrived already screwed into the ceiling with the cord going out through the little slot they put in.

You don't really need to do anything to get the gradient (at least I haven't had to), it's just a matter of tweaking the settings on the thermostat so that you could get a good basking temperature without overheating any of the surfaces.
