(1) Do MVB's lose their effectiveness (ability to transmit UVB) the further they are from the enclosure? I have a 160watt MVB that is hanging from the ceiling about 3 feet above the enclosure. It keeps my baby sullys nice and warm (90-92 in the hot spot) but I'm concerned about them getting those nourishing UVB's.
(2) I know that sunshine filtered through a glass pane is useless but what about the above UVB shining through a screen. (Like the metal type that you would put on top of a glass tank)
Thank you for you help!
