I agree that solid state lighting has come to market relatively quickly, but I know they were being discussed as much as 10+ years ago. I would not have thought UVB LED's would be available on the market as soon as 6 months, but I noticed that the UVC LED's went from scientific papers to production pretty quickly. I'm pleasantly surprised to hear production should occur pretty soon, as I was so angry that I could only find UVC LED's when I was looking. :x Sure, if you want to cook your frog or kill your eggs, UVC is fine, but who wants to do that?
