I guess they are not actually Radiant heat panels?!! Mine makes only 2 maybe 3 degrees of difference and I can feel a very marked difference in air temp. This for me calls into a HUGE safety issue with them as they easily get to over 160º (mine states 190º in the specs) and this would mean they would be capable of heating air temps dramatically over the safe temps. Interesting I wonder why they have change since I got mine a year or two ago? Mine are just flexwatt in a plastic box with some fibreglass. Does the housing get warm?

CHE and RHP emit IR radiation snakes see this just fine. I like lights as they warm the whole ceiling and the air so that rather than a bright spot it would be a over all light area. That is why I pick blue as studies show royal pythons have limited response to it. Red being in the IR family we know that they hunt via IR they are extremely sensitive to.
