Ushio in collaboration with Columbia University has launched the first UV lamp that can eliminate the coronavirus without causing skin cancer or eye problems. Such lamps could soon be employed in public places such as transportation and offices. Quite amazing, I wasn't aware of the fact that UV rays of a particular wavelength could kill viruses.

UV lamps have been widely used as an effective means of sterilization, notably in the medical and food-processing industries. But conventional UV rays cannot be used in spaces where there are people, as they cause skin cancer and eye problems. Ushio’s new lamp, however, emits UV rays with a wavelength of 222 nanometers, as opposed to the conventional 254-nanometer wavelength, making them lethal to germs but benign to humans. At this particular wavelength, the firm said, UV rays cannot breach the surface of the skin nor the eyes to bring about cancer-causing genetic defects and other damage.

Care222™ is a new disinfecting light source that, even though not harmful to the skin or eyes of humans or animals, deactivates bacteria and viruses in the same manner as conventional ultraviolet sanitizers. It can be installed in a high location, such as on the ceiling, to irradiate its entire surroundings. This makes it possible to deactivate or eliminate a wide variety of viruses and bacteria both in the air and on environmental surfaces. Ushio provides these lamps in modules combined with optimized power supplies. One of Care222™’s greatest features is that it can be used all the time. Unlike conventional ultraviolet light sources, Care222™ can be used even when people are present, allowing continuous disinfection of the air and environmental surfaces.

Interesting. I bought a traditional lamp prior to our vacation this year from cureuv.com.
