MH Light Question - UV Transmission?

Are all MH bulbs protected from harmful UV light? The reason I ask is that I run bare XM 15000K bulbs with no cover on them over my downstairs tank.
I've never thought about it until I was on Ebay and they were advertising MH lights with UV protected screen (piece of glass I assume).
Just wondering
