What I posted three weeks ago. .

I wrote an explanation about how I hang my lamps down inside the enclosure.
I told the audience that I hang hot items with the socket only, like a naked bulb.
oops! Actually I use aluminum hoods, for obvious reasons. But I don't cover the bottom of the hoods to protect the lizards. They can jump up and hook the rim with their toenails, but they cant hang on.
I may have said that a long time ago the screen method made sense to me. As a result my liz hoisted himself up to the screen, and stayed in that belly-up position until he got a huge normally fatal belly burn, which also burned a small area of his stomach. It took a lot of care over one year to heal.
The reason he did that was because his hab was too cool. The same with hot rocks.
So, early on, I discovered that the protective screen must get no hotter than 95F. BUT, don't let your iguana hang on a 95F screen with his belly facing the heat emitter for more than an hour.
If your ig keeps going back to the screen or hot rock, his need may be to have a warmer general environment.
