275nm and Far UVC 222nm light both can do disinfection ,what is the difference ?

The far UVClamp can be safely used in unoccupied and occupied spaces without posing a health risk to humans when used within the current exposure .

What appears to be certain now, is that Far UVc 222 nm does not cause cancer or cataracts in mice in a least one long term clinical study. Kobe University just came out with a key study on Far UVc effects that could be ground breaking in combating the COVID19 pandemic. They tested a relatively obscure UV wavelength of  far UVC 222nm in October 2013 by Columbia University Center for Radiological Research (CRR) team. Brenner et al showed the promise of limiting the spread of coronavirus, as well as more familiar viruses like influenza and measles with Far UVc light.

What is Suntech far UVC 222nm lamp UV irradiation ?  

See below test , it can reach 50μW/cm2 from distance 100cm so can be widely used in public such as bus station, train station , hospital...

What is is far UVC 222nm lamp light disinfection on germs and virus ?

Different UVC lamp irradiation has different disinfection effect as below  it depends on the UVC 222nm irradiation dose, very low doses of far-UVC light efficiently kill airborne human coronaviruses carried by aerosols. A dose as low as 1.2 to 1.7 mJ/cm2 of 222-nm light inactivates 99.9% of the airborne human coronavirus tested from both genera beta and alpha, respectively. As all human coronaviruses have similar genomic size, a key determinant of radiation sensitivity, it is likely that far-UVC light will show comparable inactivation efficiency against other human coronaviruses, including SARS-CoV-2.
