I know that uth's are more effective on the bottom, but for example with my pacman frog I have the uth side mounted to prevent it from burrowing straight down to it and burning itself as the burrow as a method of cooling themselves and they'll just keep digging down further not understanding why they aren't getting cooler.

I planned on attaching it to a lamp dimmer and checking temps frequently with a digital thermometer or maybe thinking about getting a temp gun.
