I've now put a third in there briefly while I wait and it's reading 28c. The third thermo is an eco terra one while other two are slightly cheaper ones.
When tested on it's own it seemed to kick out a bit of heat as I couldn't test other than to just take it out and plug all into mains.
Bulb issue? We will see shortly
Check the base of the bulb Newbie, see if there are any small cracks around the metal that screws into the socket. I've had a few that came in from Amazon for my bearded dragon that had a bunch of little hairline cracks. I tested them off the enclosure just to see if they would work and they did the same thing. I ended up just tossing them because of safety concerns and started going to the store and just paying more for them, since I can take them out and inspect before taking them home.
