Coil bulbs only produce UVB in one spot of the tank instead of the whole length of the tank. In an artificial setting for captive animals, you'll want the UVB to span about 2/3 of the tank as UVB bulbs are weaker than radiation from the sun, so the animals need to be exposed to more of it to compensate for that. Coil bulbs also produce an unreliable amount of UVB because of the way they are shaped and the UV wavelength they output is shorter than in strip lights, making them harsh, and can cause photo-keratitis, which is severe eye damage.
Good to hear that you were able to get the daytime temps down. If you do suspect he has an upper respiratory infection, you could pick up a lot wattage ceramic heat emitter to keep the tank temp about 80 overnight to help give his immune system a boost.
The point is that they need to cool down at night. Being hot, especially with your dramatically high temperatures, can easily lead to dehydration and disrupted sleep. If you can see the light, so can your animal. He should only be 90 during the day night time temperatures should be 65-75. If your house gets cooler than 65, then use a ceramic heat emitter instead. They emit no light, just heat.
He has his mouth open again and his beard is black he's laying in his corner he does not seem hungry I do not know what to do. I have an appointment for him on wensday. I uploaded a picture of what he looks like at the moment
