When you say the sun strikes his enclosure inside, is it through a window? If it is through a closed window, then it is useless. The needed UV's cannot pass through mesh or glass. So the sun shining into the room is no more helpful to him than a light bulb in the living room.

Glass blocks most UVB; mesh similar to window screen typically only blocks 30% or so UVB.

Exactly. So sun shining through the window isn't enough.

Not necessarily. If direct sun (before passing through screen) was 100 uW/cm², then it would be 70 uW/cm² after. That's better than a lot of bulbs. And depending on location, you could easily be getting more than 100 uW/cm² even after passing through the screen.

Well, damn, dude. You taught me something new. Thanks :)
I've always followed the thought that sun through windows was pretty much useless.

Note @jaizei said screen not glass. UVA passes through glass. UVB is blocked by glass I think. Plants need UVA animals need UVB mainly. Although I once read somewhere UVB can pass through certain glass. I can not get a definite answer on this subject. Also a bulb is after all made of glass.
Now that's confused matters. :)

Yes, the sun strikes through a window, there is no other choice unless we go out for a walk.

The 'funny' thing is that this has not happened before in such a way, be it in Winter or in Summer.

But isn't a bulb with UVB made with a specific kind of glass that allows passage of UVB? I always just thought that no one making windows was thinking, "Hm. I better use this more expensive glass to make these windows so that the basement dwellers and agoraphobics still get the benefits of sun" haha.

I think that's why they use agricultural grade glass in greenhouses.

Something new I learned. Agricultural grade glass. Never knew what it was called, but knew it was special/specific for UV passage. Thank you, the name of it is now going into my notebook

It may be horticultural glass. Can't remember. I was reading about it ages ago.

Yesterday he seemed a bit better. I'm going to video him whilst they are all outside today. He's still in his hide at the moment.
Glad to hear your tort is better, and hope to hear that he's fully recovered soon. By the way did you take him to a vet?

Please keep us updated.

From YouTube? Or from your computer/phone?
