Boston University validates Signify UV-C for coronavirus deactivation

Signify announced that Boston University has determined that a Signify ultraviolet (UV) light source would almost always deactivate the coronavirus that causes COVID-19 if dosed at the right level.

The university’s National Emerging Infectious Diseases Laboratories (NEIDL) exposed materials containing the virus to a UV-C tube lamp from Signify. It found that a dose of 5 mJ/cm2 resulted in a reduction of the SARS-CoV-2 virus of 99% in 6 seconds.

The NEIDL team extrapolated that a stronger dose of 22 mJ/cm2 would result in a reduction of 99.9999% in 25 seconds.
