I use 75 watt zoo-med basking bulbs during the day, and 75 watt zoo-med infrared night bulbs in their Vision V332 cages. In those cages, the bulbs drop-ins are much closer to the basking area than what would be usually seen in the screens covering commercial 40-gallon breeder aquariums which is why I use the lower watt bulbs. I use the vision cages for all my snakes, and found that the use the lower 75 watt bulbs seem to work the best for the ball pythons as far as temperature gradients go. I definitely will let you know how it goes though!![]()
