They are idiots for not testing this sooner... if not criminally negligent. Yet this issue could clearly be fixed by putting a UV filter over the
bulbs!
Inventors, there is an opportunity for you. To be honest I have been wondering about this very issue for years and believe that light bulbs should be
designed to match the same signature as the sun across as wide a spectrum of light as possible including UV, IR, etc.
Much more offensive to me than the poor UV performance of the bulbs is the fact that you throw away the ballast every single time with the bulb.
Ridiculous! Just like the bulbs that go into office ceilings there is no reason why they can't sell the glass tube separately from the ballast. I
just don't get it... those ballasts cannot be that cheap which is evident by the high price of the bulbs. Does anybody understand the logic there?
And one last thing... I'm wondering if HPS (High Pressure Sodium) bulbs are less toxic and more environmentally friendly. I know sodium is also a
toxic metal but perhaps not so much as murcury. HPS bulbs are also more efficient than the fluorescent bulbs.
