I think there is conflicting advice partly because we're all still learning what they need/want and partly because their natural habitat covers such a large area and variety of environments that there isn't a single right setup. I think the numbers given (mine included) are just general guidelines. The key is to provide a range and a variety so they can move around and get what they need at a given time. We're trying to boil down a very large environment into a small, static, captive environment which is difficult so we go with a best median guess. I think you're doing a fine job so far based on what I've read.
If he is alert and curious and has a good appetite he is probably a happy camper. If you're having trouble keeping the temperatures relatively consistent you may want to consider a programmable dimming thermostat which can keep the lights within a set range by dimming them as needed. Keep in mind that the temps will fluctuate during the day and by season in their natural habitat too so if there is a cool area to hide in when the temps go up he will probably go there and it's OK. From what I know they bask during the morning and late afternoon and hide during the highest temps in the middle of the day.
He is alert an does feed well plus he poops everyday so hopefully hes happy. Its just is so scary havin to guess that hes getting enough uvb an weather hes hot or cold enough x
Im hoping it gets less stressful as time goes on x
You'll always fuss over him. The anxiety is part of owning them. It gets easier once you have a routine down and you'll get more in tune with his expressions and have a better idea of if he's content or not.
I hooked up a webcam next to my enclosure so I can check on Darwin while I'm at work or away. It helps a bit to be able to poke in from my phone and see what he's up to.
That is a fun idea, then you can check on him any time.
As long as there is a good range of temperatures, then he can choose where he wants to bask & should thermoregulate. If he has a cool side he should be just fine.
