Ball pythons are borrow dwelling and nocturnal, so they don't need sunlight/UV the same way a diurnal species like a corn snake would. You don't have to worry about setting up a strict lighting cycle with artificial lighting, just the natural light that comes in through a window is fine. Your snake will do its thing on its own, so really the only lighting you have to worry about is what ever you want to use so that you can actually see your snake in its enclosure when it's not in its hide.
