Somerset, New Jersey – Signify (Euronext: LIGHT), the world leader in lighting, together with the National Emerging Infectious Diseases Laboratories (NEIDL)1 at Boston University has conducted research that validates the effectiveness of Signify’s UV-C 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’s School of Medicine, and his team have been working on developing tools to support scientific advancement in this field.2 In their research, they 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 99% reduction of the SARS-CoV-2 virus in six seconds. Based on the data, it was determined that a dose of 22mJ/cm^2 will result in reduction of 99.9999% in 25 seconds.3
“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,” said Dr. Anthony Griffiths. “We’re very excited about these findings and hope that this will accelerate the development of products that can help limit the spread of COVID-19.”
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.
