Eliza Strickland at IEEE Spectrum Calls Integration of Ushio’s 222 nm UV Lamps into Many Products One of the Top Ten Exciting Engineering Milestones to Look for in 2021

Last year, Senior Editor Eliza Strickland at IEEE Spectrum recalls, germicidal ultraviolet light found a place in the arsenal of weapons used to fight the coronavirus, with upper-air fixtures placed near hospital-room ceilings and sterilization boxes used to clean personal protective equipment. But a broader rollout was prevented by the dangers posed by UV-C light, which damages the genetic material of viruses and humans alike. Now, the Tokyo-based lighting company Ushio thinks it has the answer: lamps that produce 222-nanometer wavelengths that still kill microbes but don’t penetrate human eyes or skin. Ushio’s Care222 lamp modules went into mass production at the end of 2020,…
