Ultraviolet light can kill almost all the viruses in a room. Why isn’t it everywhere? Can special lightbulbs end the next pandemic before it starts?

Far-UVC light dramatically reduced airborne virus levels in a room where people were working, in the first study of the new air disinfection technology outside of an experimental setting.

While UV-C light is used in a wide range of sterilization applications, most keep the light hidden or localized to avoid direct human exposure. Upper-room UV-C installations are particularly ...

The emerging technology offers an alternative to conventional UVC light, which is used to sanitize surfaces but can harm the skin and eyes.

A bus being treated with ultraviolet light in Shanghai, China. Although types of UV light are already in use to decontaminate vehicles and indoor spaces, the wavelengths used are dangerous to ...

By using light on a shorter wavelength, the ultraviolet C bulbs can eliminate pathogens without penetrating skin and eyes, says Lit Thinking CEO John Rajchert.

Beam ($5,000) is an LED-based, upper room disinfection device that uses 265-nanometer ultraviolet light to create a disinfection zone located above people in a room.

Right now, if you want to get 222 nm ultraviolet light (the standard for far-UVC), you need what’s called an excimer lamp. These work the way fluorescent light bulbs do: by putting an electric ...
