...the mercury-vapor lamp. It produces a potent wavelength of UV-C light-254 nm–that has proved devastating for nearly any genetic material in its path, including that of a coronavirus or a human.
Much of the trick to wielding germicidal UV light against the spread of disease lies in finding a way to keep people safe from that light.
To keep humans safe, the fixtures, which typically cost a few thousand dollars each, are placed at heights above 2 meters, and nonreflective baffles direct the ultraviolet energy upward and outward.
