    I thought that the metal halide bulb (glass) was UV shielded?........

    I don't believe the HQI's are shielded.  The real small ones...

    MM, sorry, I think I have you confused with another thread!

    Sue,

    No you are not confused as some double ended MH bulbs do not have an outer envelope that has the UV coating. In any case, you really should have a glass shield between the bulb and water. If the tinest splash hits one of those bulbs there is a good chance it will explode, showering the tank, and possibly you, with glass.
