I currently use CHEs, and use them on a thermostat, but am concerned about the increased long term potential for fires or other hazards. I have been doing some reading on the radiant heat panels, such as those made by Reptile Basics and other herp brands. Has anyone made the switch to radiant heat panels? Are they more efficient for similar wattage units? Can they be mounted on the side walls of the enclosure? Due to size, I'd have to mount them sideways, and probably not overhead. Safe for contact with the tortoise? Anyone who is willing to share their experience with RHPs would be much appreciated. Thanks.
