lighting for my ball python

I also had a question about head.. I have an UTH, but I dont think thats keeps the tank warm enough because my Bp just stay where the UTH is at, what else can I use to help keep my tank at 90 degrees?

Heat** ..sorry

I have a UTH for my bp...but he only stays where the heater is, I know the rest of the tank is too cold . What can I use to help keep the rest of the tank warmer?

An overhead lamp (red or black bulb or CHE) will help with your ambient temps.
