Hi, I use radiant heat panels now and wouldnt go back to anything else. I use them in a hide box that contains the heat panel on a thermostat. The hide box has a small door for the torts to go in and out of which helps maintain the heat and humidity. Elswhere in the enclosure is a basking area for the torts to bask and heat up to where they need to be. The heat panels are working for me the best of all other types of heat I tried. Hope this helps, just my findings.
