Well I came home last night to find one of my MHs frosted over with a red color and not working. The bulb is a Coralife 175 10K. The frosting is on the inside of the glass covering. I am scared to put another bulb in the mogul incase my ballast caused this. Has anybody seen this before? Maybe I'll buy a really cheap regular 175MH to test it. Anybody have an old 175 they would part with. I would pay shipping and give many praises.
