do you reccomend a specific light? my goal is to heat the air and provide UVA, do you think I should get a 25 watt or 15 watt, what bulbs do you use?
I understand your goal. I don't think you can do both those things with a single bulb.
Please describe where the 8 x 12 inch heat mat is placed.
What kind of room light has she? My photoperiod lighting is only good for lighting an enclosure during the day if leos have limited daylight. I have that 15 watt bulb dimmed to half power, so it's basically a 7.5 watt bulb.
I recommend a ceramic heat emitter (CHE) to warm the air,
but NOT if she climbs the background. Every other bulb is too bright during the day, because that's when leos sleep. CHEs are bulbs that produce heat but no light. I don't have a specific wattage to recommend.
The CHE would need a separate thermostat. If Citrine climbs, there is no way a CHE that heats the ground to adequate belly temps would be safe when she climbs.
Overhead heating will not fix the problem that her heat mat is too small.
A ground temp increase to 72*
might be too hot right beneath the CHE! I think she needs ground temps of 88-90ish to be comfortable prowling around.
