A study by the company Signify and Boston University has published the results of new research.

Since the health crisis of the Coronavirus and the Alarm State began across Europe, one of the items that experienced a sales boom was ultraviolet light sterilizing devices. These gadgets consist of a box in which to put the mobile or other objects – devices and activate a series of UV rays that will sterilize the terminal. In fact robots are even used in Spain that disinfect hospitals using UV rays.

UV-C ultraviolet light

But could UV light be used not only to disinfect, but to kill COVID-19? The manufacturer of lighting material Philips Lightning -which has changed its company name to that of Signify- decided to put the degree of effectiveness of this type of light to the test, and for this it partnered with Boston University, USA, in an investigation jointly led by Dr. Anthony Griffiths, associate professor of Microbiology at the Faculty of Medicine, as stated by the Dutch company in a statement.

The goal: To test the effectiveness of UV-C ultraviolet light in deactivating the SARS-COV-2 virus that causes COVID-19, something that is achieved after only a few seconds of exposure. Griffiths and his team inoculated different materials with samples of Coronavirus, and then tried to eliminate it with different doses of UV-C ultraviolet radiation through devices developed by Signify, evaluating in the process the inactivation capacity under various conditions.

99% removed in seconds

The result? A virus inactivated in seconds: As we read in Europa Press, the team applied a dose of 5mJ / cm2, which resulted in a 99 percent inactivation of the SARS-COV-2 virus in 6 seconds. Based on the data, a dose of 22mJ / cm2 was determined to cause a 99.9999 percent reduction in 25 seconds.

Therefore, the study has “confirmed the effectiveness of UV-C lamps as a preventive measure for companies and institutions that want to provide virus-free spaces,” according to Eric Rondolat, CEO of Signify, who has already announced that it will increase its capacity. production in the coming months and that will put its UV-C technology at the service of other lighting companies.
