I do not, but it is close to where he hangs out and its brand new. I will get one of those as well. Its hottest during the day, so I don't use the coil then. That puts the temp to that 80 range. At night it cools off when the Megaray goes off. That is when the coil comes on. That keeps the temp anywhere from 65-70. I also monitor the heat in the room itself via thermostat and the humidity is easily controllable via the fan and the door. I try to keep it as close to 50% as I can. The humidity is the hardest part because he obviously needs water, but since its the bathroom, it elevates rapidly with only a little bit. I try to get the majority of the water where he actually hangs out in order to get his body misted. He also has a dripper I made from a plant irrigation tube and a pump. Its just keeping an eye mostly. I have a live-in boyfriend who helps monitor levels for both critchers. I had looked into the raygun when I saw someone mention it somewhere else. I figured since the bulb is so new, and he is pretty near to it, that he should be getting all the rays. However, I will get on that asap. I do notice when the temp climbs during the day that I find him either behind the leaves, over under the pool light on the pothos l, or down on the wooden framework I built. I guess what I'm getting at is that he is in fact figuring out his internal temp gauge, so that's comforting. ?
