   I bought some 400W Hamilton MH lights. They do not have a shield over the bulb like most I have see. Is this needed for any uv filter or is just to protect the bulb from water?

   When I had MH, my Hamilton bulbs never had shields either. Couldn't help you with other brands tho, sorry.

   The shield is a UV filter

   the shield is only really needed for double ended bulbs. single end bulbs are already shielded. so no worries

   Yeah, the mogul bulbs have a glass shield around them and don't need a glass panel like a double ended bulb. Didn't know hamilton made 400w single ended MHs though.

   So as long as I use a Mogul (single ended bulb) which I am, I do not need a uv shield right?
