Signify collaborated with the National Emerging Infectious Diseases Laboratories (NEIDL) at Boston University in the US on a research that validates the effectiveness of Signify’s UVC light sources on the inactivation of SARS-CoV-2, the virus that causes COVID-19.
Since the start of the SARS CoV-2 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. During their research they have treated inoculated material with different doses of UVC radiation coming from a Signify light source and assessed the inactivation capacity under various conditions. The team applied a dose of 5mJ/cm2, resulting in a reduction of the SARS-CoV-2 virus of 99% in 6 seconds. Based on the data, it was determined that a dose of 22mJ/cm2 will result in a reduction of 99.9999% in 25 seconds.

Signify CEO Eric Rondolat commented, “I’m very happy about the fruitful cooperation with Boston University in the fight against the coronavirus. Boston University has validated the effectiveness of our light sources as a preventive measure for companies and institutions as they seek ways to provide virus-free environments.”
Rondolat said that given the potential of the technology to aid the fight against the coronavirus, Signify will not keep the technology for its exclusive use but make it available to other lighting companies. In addition, the company will increase production capacity to service the growing need for disinfection.
