Not nit-picking, it's just important that the info about uvb + heat is accurate . The screen does not block 50% uvb, and not all types of lights need to be under the screen. Here is the testing done on the 2 types of screen that is used on tank lids. Scroll down to the sub heading discussion.

I agree, which is why I pointed out that if she had a T5 it could be mounted on top of the mesh...And I have read many places, including on here and in articles online that a Reptisun T8 tube can have over 50% of it's UVB blocked by metal mesh, it's completely dependent on how close together the holes in the mesh are. I don't think it's a good thing to have even 30% of the UVB blocked anyway, but your numbers are dependent on other factors involved, as well as where you read. I suppose that's true with most information, but the bottom line is that it's better to mount a T8 UVB tube inside the enclosure. If you disagree about that then you're entitled to your opinion, but it's just that, an opinion. There are several threads on here, including a sticky discussing why you should mount your UVB tube inside the enclosure if it's not a T5, which is exactly what I said. Better safe than sorry.
I didn't mean to sound rude, but it seemed like you wrote an entire post just to critique what I wrote, and what I wrote is correct. The OP didn't give enough info about her lighting for me to give exact answers and advice, so I pointed that out, in general terms: T5 on top of mesh, T8 inside enclosure.
I'm not arguing, I don't want to at all, but I feel it's important to give people posting with sick beardies ALL the information from all sides. There are many people on here who believe in mounting any 10.0 UVB tube, which is all the OP said about her light, inside the tank if it is only a T8. And I'll post the links to the articles I've read that state that metal mesh can block over 50% of the
UVB light from a light, depending on the size of the holes in the mesh, for you to read in a bit. You should check them out, in all seriousness, one of them includes a very interesting controlled study involving the different mesh patterns and the effects they have. I was surprised that such a small difference in the hole size of the mesh made such a large difference in the amount of UVB blocked.
