My Dragon seems to often be next to the log that I have for his basking spot. The top of the log is 15 inches from the bottom of his UVB. It’s an Arcadia 12%. The ambient temperature in the tank is between 90 and 95 on the hot side in between 80 and 85 on the cool side. His basking spot is 99 at the hottest point and goes cooler as he moves to the left. He is sometimes actually on top of the log but I guess my question is is he getting enough UVB sitting near the log or do I need to change things around like lowering the light so that it is 15 inches from the floor?
