The National Electrical Manufacturers Association (NEMA) Lighting Systems Division has endorsed the Global Lighting Association (GLA) position statement on germicidal ultraviolet irradiation.
According to GLA, germicidal ultraviolet irradiation is a proven methodology for inactivating viruses on solid surfaces, in water, and in the air. As such, it is expected to be a useful tool in the fight against the COVID-19 pandemic.
UV-C is a category of ultraviolet light with wavelengths between 100-280 nanometers and is the most effective UV light for disinfection. UV-C devices are considered safe if they meet the applicable safety requirements provided in the International Electrotechnical Commission and/or Underwriters Laboratories Standards or other regional safety requirements.
