Will a Screen Top Interfere?

[HoomanSlave]

Hi!
The UVB bulb I am buying is a Reptisun T5 10.0, with a basic fixture from Carolina Custom Cages.
My question is if a screen lid, like the ones sold by Exo Terra, are okay or if they will decrease the UVB. How big should the holes in the screen be? Could I use something like chicken wire to make a custom one if the Exo Terra ones are not okay?

Yes, the screen doesn't allow a good portion of the UV rays to pass through. Can you figure a way to mount the light to the under side of the screen?

Maybe, I'll try it when I get my terrarium set up.
