Ball pythons need the cool side to be 78-82 degrees and the hot side needs to be 88-92 degrees.

I would replace both lamps (the bulbs that is) to these:http://m.petsmart.com/mt/www.petsmar...3&lmdn=Reptile

The cool side should be a 50 watt and the hot side a 75 watt. Both lamps should be on lamp dimmers so you can adjust the amount of heat they put out.

UTH's are great but require a thermostat and they do not effect the ambient temperature.

What are you using to measure your temperatures and humidity?
