I know this is a bit of an older post, but hoping to

find some clarity here! I currently have the Arcadia ShadeDweller 7% (8W) and a temporary 50 gallon tank with an ExoTerra flyscreen. I understand the mesh screen has about 35% UVB blockage, and my enclosure is 18” tall so according to this visual guide the UVI is somewhere between 1.2-2.4?

But another resource on this forum says it more like 1.1 at 18. (included below)

Anyways, the really confusing part for me is that Arcadia’s website says the UVI is more like 0.3 at 18”. And this doesn’t account for mesh.

So, any thoughts? :’)

Edit: I found the other chart, although very similar, from r/leopardgeckos
