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.)
