Are these the same LEDs as in what is being sold in those cellphone disinfectors?

“Ultraviolet radiation is a common method of killing bacteria and viruses. Now, researchers from Tel Aviv University have proven that the novel coronavirus, SARS-CoV-2, can be killed efficiently, quickly and cheaply using ultraviolet (UV) light-emitting diodes (UV-LEDs) at specific frequencies.

“We discovered that it is quite simple to kill the coronavirus using LED bulbs that radiate ultraviolet light,” said Prof. Hadas Mamane, head of the Environmental Engineering Program at Tel Aviv University’s School of Mechanical Engineering, who led the study with Prof. Yoram Gerchman and Dr. Michal Mandelboim.

In her team’s research, they managed to kill the virus using cheaper and more readily available LED bulbs – 285 nm vs. 265 nm bulbs – which consume little energy and do not contain mercury like regular UV lamps.

UV-LEDs are new and still expensive.

UV disinfectors use inexpensive UV bulbs that generally wear out in about a year. The glass bulb clouds up.

Far-UVC works best as it kills virus but doesn’t cause cancer. The wavelength is so short it doesn’t penetrate human tissue.
