Hey guys I'm moving my beardie from his 20 gallon long into a 48×24×18" pvc enclosure. I'm just trying to get the temps dialed in before I move him. I have tried a 50 and 38 watt halogen and both were too hot. I had a couple other bulbs laying around one was a 100 watt zoo med that was reading about 117 and the other was a regular 75 watt incandescent and it only reached about 90. I guess my question is where do I go next. Thanks
