Before everyone gets their panties tied into a knot, I know that the glass keeps things safe and the issues about the UV and high voltage. I'm over 60 and don't need mothered! My question is more out of curiousity, but does anyone have any experience with the metal halide bulbs that have their outer glass shell removed or broken? I know the glass filters out most of the UV light, but I'm curious what frequencies and how powerful the blocked UV is. Is it mostly UVC, A, B? I used to mess around with the old school sun lamps that used the quartz arc tubes, and have seen it burn the shit out of plants in short order, but I was curious just how much of the differing UV bands are being affected.
Any armchair scientists out there?
