I don't believe they even need a day/night cycle. I'm sure racks let some light in, but many srsbsns breeders have only heat tape and humidity management. I stopped running day heat bulbs because the ones I was getting were lasting about 3 to 6 weeks. The red night bulbs last forever. If you have a heating element that can keep his hot side and ambient temps right you would be fine. I don't see why a cold side and hot side UTH wouldn't be all that you needed. A flourecent aquarium type bulb would be ideal if he/she is in a tank. That way you can view when you want and have light in there for maintenence. Also I'm sure the snake would appreciate a little light if you feed in tank.
