Yes, I do rest my lights right on top of the screen and it works out great. The exo terra hood covers the back half and my day/night heat lights are on the front half. I have a piece of drift wood that reaches a little more than half way up the tank, with branches at various levels. I also have a reptile hammock (even though it's cheesy looking the frogs love it) about 6" from the top of the tank (not directly below a light). The frogs usually choose one of those places to sit. If they want to be closer to the top of the tank they can go all the way up and just sleep on the glass, but that's not very often.

Here is a picture if it helps. The tank is pretty basic right now because I'm treating for parasites and I'm in the process of building a planted 75G vivarium.
