Signify and Boston University Validate Effectiveness of Signify’s UV-C Light Sources on Inactivating the Virus That Causes COVID-19

The quality of the air we breathe, the water we drink and the cleanness of surfaces – they all have a profound effect on our health and well-being, as we are permanently at risk of contracting or spreading viruses and bacteria. And while Signify's UV-C lamps don't treat people directly, they can make a difference by helping to neutralize viruses and bacteria that might present a danger.

UV-C radiation is a known disinfectant for air, water and surfaces that can help mitigate the risk of acquiring an infection and has been used extensively for more than 40 years. Furthermore, all bacteria and viruses tested to date (many hundreds over the years, including various coronaviruses) respond to UV-C disinfection.

Since the start of the COVID-19 pandemic, Signify, the world leader in lighting, has teamed up with the National Emerging Infectious Diseases Laboratories (NEIDL) at Boston University in the US to conduct a research, aiming to validate the effectiveness of Signify’s UV-C light sources on the inactivation of SARS-CoV-2 virus.

During their research, Dr. Anthony Griffiths, Associate Professor of Microbiology at Boston University School of Medicine, and his team have treated inoculated material with different doses of UV-C 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.

– 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 – said Eric Rondolat, CEO of Signify. – 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. To service the growing need for disinfection we will increase our production capacity multifold in the coming months.

Signify is the leader in UV-C light sources and has been at the forefront of UV technology for more than 35 years. It has a proven track record of innovation in UV-C lighting, which is designed, manufactured and installed in line with the highest safety standards.
