Research validates UV-C light is effective against COVID-19

Together with the National Emerging Infectious Diseases Laboratories (NEIDL)at Boston University in the US, Philip's has conducted research that validates the effectiveness of their UV-C light sources in the inactivation of SARSCoV-2, the virus that causes COVID-19.

Since the start of the COVID-19 pandemic, Dr. Anthony Griffiths, Associate Professor of Microbiology at Boston University School of Medicine and his team have been working on developing tools to support scientific advancement in this field. In a study conducted by the National Emerging Infectious Diseases Laboratories (NEIDL) at Boston University in a laboratory setting, Signify’s UV-C light sources irradiated the surface of a material inoculated with SARS-CoV-2 (the virus that causes the COVID-19 disease) with a UV-C irradiance of 0.849 mW/cm2, Philip's UV-C light sources reduced SARS-CoV-2 virus infectivity to below detectable levels in as little as 9 seconds for dried virus and 4 seconds for wet virus.

"Our test results show that above a specific dose of UV-C radiation, viruses were completely inactivated: in a matter of seconds we could no longer detect any virus.”

The test results suggest that UV-C is an affordable and effective tool for inactivating SARS-CoV-2 in inoculated surfaces that can easily be deployed to help combat the current COVID-19 pandemic.

Philip's have published a white paper on air, surface and object disinfection using UV-C light that includes the research results as well as information what UV-C light is and how it works.
