Thought I'd post some pics of my leos enclosure. It is 39 1/2 x 20 1/4. This is his temp set up until I build his table. I use a 150w black bulb for heat and it keeps the temps between 92-94, and an 18 in strip bulb for uvb. The heat lamp is not just clipped on the side, but also rigged from the top with fishing cable to ensure it doesn't fall. The hot side has a humid hide with sphagnum moss and some fake vines for shade and security.
