Don't have a reptile myself, but my daughter has a veiled Chameleon named Spike. Two years ago for Xmas I built her an enclosure. The top is removable & all the wiring for the lights is up there. I've also been wondering if any lizard owners are switching to LED lighting, particularly for UV. I need to figure out another Xmas present for her, so a cool UV LED fixture would be just the ticket.
The photo is from just before completion & there's been a mod or two since. I used West System epoxy left over from my cedar strip canoe build to water proof the floor & there's a kitchen sink drain fitted down there in case it needs to be drained. The rest of the enclosure is finished with varnish. I had to add a spacer between the cage & the top earlier this year because Spike was getting too close to the light & cooking his back.
Sorry, no pics of the actual critter.
