Any Metal Halide Experts on Here?

Hey all - I'm a noob, so pardon my ignorance in advance.
I like to take health risks into consideration whenever I undertake a venture that will expose me to new chemicals, rays, waves, etc...
I've been reading about health risks due to exposure to damaged metal halide lights. What exactly constitutes a damaged MH light? Would I know if mine was damaged? I've read about cases involving damaged MH lights in gyms and such - are they talking about lights with broken outer bulbs/casings?
Also - does anyone know about eye/skin damage associated with non-damaged MH lights? Would I be better off wearing long sleeve shirts and sunglasses when I'm working near my light?
And last but not least, am I just being paranoid?

^^^true. And yes you are being paranoid.

I'd just as soon lick a stripper's butt crack as look at one, but that's just me. I don't mind the taste of butt crack sweat, but I'd kick myself if my skin or retina was permanently damaged by my lights.

I spent 2 hours under my lights and my dick fell off......I was rushed to the hospital for a addadicktome
