Yep, I bet that is it. Air temps do not mean much to a snake if surface temps are cool. A snake's body is flat against the ground. Whatever temp the ground is, the snake is.

You need a bulb that directs heat down, and you need branches or something that the snake can elevate itself to heat up. Or an undertank heater. But, in my experience with corns, and part of what makes them such a great snake, you can provide branches and the snake will climb up and rest closer to the bulb.
