Back with more questions... Just paranoid me over here

1. Is this obese? I'm not sure what the best range is for male panthers. I for sure know he's overweight tho.
2. If I buy an Arcadia UVB bulb- is it this one?
Arcadia bulb. I have the Reptisun T5 HO 24" linear fluorescent bulb with reflection UV that we talked about earlier and want to make sure it fits!
3. is this okay for the basking bulb? Zoomed Repti basking 50W bulb. I see that lightyourreptiles.com has this one-
chromalux. I believe I have an 8" dome.
4. Should I use this?
dimming thermostat or
light fixture with dimming. I wasn't clear on it on the husbandry form so I wanted to double check. I am guessing it is supposed to be a dome lamp and not a linear since it's for basking.
Thank you as always!
