yes you need something protecting the bulb from the water...it can shatter if water touches the bulb after its been running a while

your tank is gonna be pretty hot, the bulb is made of glass why are you worried about it being close to glass

I was told to use tempered glass as that will not shatter as easy. I don't have the hqi though but the thought if my fish splashed at the surface and that hitting any hot bulb just scared me so i went to a local glass shop and got the tempered to cover the whole canopy and put some extra fans in it.
