COVID-19 has brought a new focus of attention to a tool that is relatively little used in many industries: UV energy. Scientists have known about UV-C’s disinfecting powers for decades. Hospitals and healthcare settings have used UV products for years. A scientist from Columbia University recently demonstrated through research that UV-C wavelengths can inactivate COVID-19 by 99%. There is solid evidence behind UV technology.

According to the research, “Conventional germicidal UVC light 254nm wavelength can be used to disinfect unoccupied spaces such as empty labs, hospital rooms, schools, or empty subway cars.

SARS-CoV-2 It is transmitted to a large extent through drops, aerosols caused by coughs and sneezes, it is important to have a tool that can safely inactivate the virus while it is in the air, especially when there are people nearby, so this too far UVC light could be used in combination with other measures, such as face masks and hand washing, to limit the transmission of SARS-CoV-2 and other viruses


But what lighting products should you trust? Which ones really work? And are they all safe from COVID-18?



Although UV products are nothing new, there is no standard regulatory process. That means that new UV products that have entered the market during the pandemic may or may not work like LED lamps or LED bulbs.

Regulating UV lighting fixtures and replacement products is especially important due to safety guidelines and recommendations. An article recently published by INC. The problem of regulation stands out. A rotation of up to 20 seconds is recommended for anyone under the portal to ensure a more effective disinfection cycle.

But it was also confirmed that rays cannot penetrate the tear layer of the eye or the outer layer of dead skin from dead cells, so it cannot reach or harm living body cells.

On the other hand, it should be noted that not all ultraviolet (UV) wavelengths are the same. UV-A and UV-B rays, the types we receive here in Tierra del Sol, have important uses, but UV-C is the preferred ultraviolet light to purify air and water and to inactivate microbes.

If there are questions about a product backed by so much research that it has already passed certain quality tests, it only questions how many other products should be regulated before they hit the market. Not all UV products you find on the internet are really effective, and buying the wrong product can really come at a cost. A perfect example is the large number of UV wands (using mercury) on the market.
