uv-radiation

Hi, I wondered how much ultra violet radiation is there in double ended HID or HID lamps in general? I already have glasses, but how about my plastic stuff in that room, will it degrade like when in the sun outside? e.g. I can buy a switch box in uv stable plastic and a not uv resistant plastic...
