I'm new to owning snakes, just 1-2 years. But BP's do not need light, its better just to use normal around the house lighting, you dont need any special heat lights, or basking, ONLY if thats your only means of tank heating which I hope it isnt, snakes need belly heat to help with alot of things, such as digestion of there food, they will stay in there hides most of the day, and at night, when the lights are off, they will become more active. I would just use another means of heating, like UTH's, and heat tape depending on your setup and forget about the light.
