well in regards to the ceramic heater ... read my sig. A fluorescent light would be fine but the Ball python will not benefit from it. As long as there is natural light in the room you are the cage in you will be fine. Believe me sometimes thinking less is more benefitial than over doing it. Plus lights tend to dry out the enclosure considering u also got the 2 cut outs it might be slightly difficult to monitor the humidity. I really have no experience with T3 cages.
