Ultraviolet light to inactivate the virus that causes COVID- 19

Reading Time: 2 minutes

For more than 40 years, UV-C light has been used to disinfect air, water and surfaces. The Ultra-Violet radiation found in the C wavelength spectrum can help decrease the risk of acquiring an infection by damaging the bacteria or virus so it is unable to replicate. Bacteria and viruses tested to date (many hundreds over the years, including various coronaviruses) respond to UV-C disinfection. In laboratory testing, Signify’s UV-C light sources inactivated 99% of SARS-CoV-2 virus (the one responsible for COVID-19) on a surface with an exposure time of 6 seconds.

Validated by Boston University, this specialised UV-C light product will soon be available in Hong Kong. Signify, formerly Philips Lighting, the world leader in lighting, together with the National Emerging Infectious Diseases Laboratories (NEIDL)1 at Boston University in the US have 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. This product is coming to Hong Kong for consumer use and will help ensure a safe virus-free environment for your family.

“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, Associate Professor of Microbiology at Boston University School of Medicine.

Signify, the company

Signify, the company behind this innovation, has been at the forefront of UV technology for more than 35 years. “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.”

“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.”

From early September, Signify is set to launch the first UV-C disinfection device to Hong Kong consumers. The Philips UV-C Disinfection Desk Lamp [HK$839] is compact and easily transportable, integrated with microwave sensor and smart control logic to secure user safety and voice guide for simple user friendly operation.
