New study shows LED bulbs can kill coronavirus in minutes

It is possible to kill the new coronavirus through LED bulbs without having to use other methods such as alcohol-based products to achieve this.

Just recently, researchers from the University of Tel Aviv in Israel published a report in the Journal of Photochemistry and Photobiology B: Biology indicating that ultraviolet LED (light-emitting diodes) can efficiently kill coronavirus.

According to the study, reports the Standard, Professor Hadas Mamane who was the lead researcher said the LED bulb’s ultraviolet light radiation kills coronavirus in a matter of minutes.

In scientific explanation, the report indicated that UV radiation weakened the virus because it inactivates “pathogenic microorganism” but is fully dependent on wavelength.

When carrying out the study, the researchers used an optimal wavelength of 285 nm and 265nm and it managed to kill the virus in about 30 seconds.

“We killed the viruses using cheaper and more readily available LED bulbs, which consume little energy and do not contain mercury like regular bulbs,” Prof Mamane said.

Prof Mamane added that it is possible to install the LED bulbs in ventilation systems and air conditioners for sterilization process of the air meaning those in the rooms will not contract the virus.

In the market, 285nm LED bulbs available and cheaper.

On the flip side, use of UV light from the LED bulbs exposes one to harmful rays which is now what Prof Mamane and team are left to work on.

The system should fully cushion a person from the harmful UV rays.

Currently, the use of alcohol-based products or those with 70% sodium hypochlorite have been recommended by the World Health Organization (WHO) to disinfect surfaces and areas with a heavy flow of human traffic.
