As long as they have the proper heat gradient (hot spot and cool end), you can accomplish it however you need. If a room stays over 75 degrees, then a thermostat-controlled UTH is all you need. If your room is cooler, you have to make adjustments since a UTH won't warm ambient temps. In the OP's case, a UTH would allow a proper hot spot without raising the entire tank's ambient temps so much (heat bulb can be raised farther away).
Thanks for the info. I am still learning something new every day.
