I have a 40 gallon glass terrarium with 2 front doors, a side vent, and a metal mesh top. I have a 36 inch hood with a T5 desert bulb (120 watt) that covers the top of the terrarium. And I have a ceramic heat emitter above one of my dragons basking spots. Both sit on top of the metal mesh top. I will include a picture if you want to get a better idea of my set up. My dragon is 18 months old a roughly 20 inches in length. (She spends most of her time on the drift wood so I moved the heat emitter there) http://imgur.com/YmxIUwO
Her cage averages about 82 degrees in the winter and 88 degrees in the summer. Right now when she sits under the heat emitter her body temperature is 85 degrees. Is she at a good temperature or should it be higher? I could cut a hole the metal mesh so less heat gets absorbed. But I don't want to do that unless someone tells me her body temperature is too low.
