Success with LED and SPS

I did a little more digging re the UV issue & found this article. They've carried out some measurements on various bulb types, technologies, their UV output & how much UV-A in particular actually makes it through some of the so called glass shields that envelop lamps. UV-B & -C are downright nasty & can really hurt you as well as most any living thing.
