Yeah i’d Say no light. Unless your room drops below 55, and @kinyonga says a heat emitting bulb, what she means is a ceramic heat emitter. It produces only heat, no light. Your Cham doesn’t need any lights on at night cause it could mess with his sleeping patterns. Temp drops are actually beneficial. They come from a climant that’s substantially warmer during the day then at night. A 10-15 degree temp drop is actually quite natural.
