really it wouldn't matter as no UV globe/tube emitts any where near as much UV as what the sun does. So whatever globe/tube you choose to use will be fine.
To be honest I don't know too much about snow blindness but if sufficient hides and places out of direct uv exposure are provided I don't see how they could.
Yeah ive got a few hides in there but ive also got a branch hanging from the roof about 30cm away from where im going to put the UV. Its an 18 wat tube is this too high?
