I've done a lot of research regarding temperatures necessary for a BTS. I typically see between 90 and 100f in the hot end (so about 32 to 37.7c). However, I am seeing conflicting information as to whether this is air temperature or surface temperature.
I have thermometers in the hot end and cool end. These are measuring air temperature as they aren't on surfaces. Typically the hot end is measured at around 33-36c when using these.
My confusion stems from the fact I also have an IR heat gun that measures surface temperature . In the hot end under the bulbs the temperature can range from high twenties up to mid thirties. HOWEVER, there is a resin hide there whose 'roof' is typically in the very high thirties when measured with the heat gun, but can go as high as 55-58c in places on it. If I measure the air temperature near these spots we are again talking mid 30s. My skink regularly basks on top of the hide for a few mins, but I obviously want to make sure he is safe there. The actual bulb bottom is about 9-10 inches above the top of the hide. The bulb is currently 50w halogen, with another 50w on dimming as backup. (See pic - left bulb is on constant [25w in pic, but now 50w], right bulb is dimming to maintain temps, 50w)
So, my question is - should I be using the IR gun temperatures or the ambient air temperatures? I've read conflicting reports. 55-60C (even in occasional very small spots) seems very high, but if I lower the bulb strength the surface temps on the tank itself (not the hide) would be in the mid-high 20s which seems quite low. I guess I could move the hide from under the bulbs but I'd still like the question answered for reference
So, what are safe surface temperatures for the skink, be they on top of the hide, or on the tank floor.Thanks!
