Help with my Ball Pythons cage set up.

I will attach a picture of how it looks then I have a few questions.

Currently, I run that light all the time, its a black light that gives off heat that I guess doesn't mess with their cycle, I was told you didn't need to run a day time light. I just bought a heating pad, that I thought I should also put on the side with the light I run 24/7. to make that side of the cage much warmer. Obviously his water bowl is in the middle, and then his cool side with the other hide. How does that look and will that work with the heating pad?

I'd also like to add that while the temperature guage isn't directly under the heat, It only reads about 75 and the humidity atm is like.. 70% (my room is very hot during the summer) That's why I bought the heat pad, to warm up that side even more.
