Wow, a simple search on Amazon even pulled up far uvc lamps.

  Be very careful with those; retinas are particularly susceptible to UVC, as the atmosphere blocks all of it; we've never evolutionarily had to deal with it before. https://www.nbcnews.com/health/health-news/doctors-warn-about-eye-damage-uv-lights-kill-coronavirus-n1249009 https://www.nbcnews.com/health/health-news/doctors-warn-abou...

    So wouldn't that apply to the lights described in the article this thread is about? How can the article say those are safe?

      The article describes "far-UVC" light, which they say is new. > Far-UVC light has a shorter wavelength than conventional germicidal UVC, so it can’t penetrate into living human skin cells or eye cells. But it is equally efficient at killing bacteria and viruses, which are much smaller than human cells. The UVC lights on Amazon are presumably plain old eye-destroying UVC. (If you want to use UVC, get it installed in your air ducts, where eyes don't go.)

        Except the comment explicitly said that amazon has "far uvc lamps".
