Do you have a digital with probe end that you can verify temps from the ir gun with? Sometimes it guns dont read certain surfaces correctly.
Or if you could tell us what material your basking site is made of?
So is it the exo terrain solar glo? Uvb and heat?
Those tend to get pretty hot, usually. How far away is it?
Would you be able to post a picture?
I'm using 50w bulbs in my 4x2x2s and its keeping my temps almost too warm! Lol. But that's why I typically like uvb and heat to be separate bulbs, that way I can adjust temps like that.
