Won't shoot the messenger. Will quote from the article.

Some experts are skeptical that even after the work is done Healight will amount to much
. There’s an important distinction to be made between forms of ultraviolet light. Ultraviolet light exists on a spectrum split up by wavelength; ultraviolet A (UVA) light has the longest wavelengths, followed by ultraviolet B (UVB) light, while ultraviolet C (UVA) light has the shortest. Aytu BioScience’s Healight uses UVA light. Another form of ultraviolet light that’s being explored to combat coronavirus, though to kill the virus in the air not in humans
, is a specific, very short form of UVC light called far-UVC light.
Dr. David Brenner, director of Columbia University’s Center for Radiological Research, has been exploring ultraviolet technology to combat coronavirus, and he has seen promise using far-UVC light. He doubts UVA light would work and thinks it may even be dangerous to internal tissue.
“It’s an interesting idea, though I have doubts that it would work,”
Brenner told the Dispatch Fact Check. “The airways and lung are pretty complex geometrical structures, so any small amount of material between the virus and the UV light source would protect the virus.”
“In addition, UVA is not particularly effective at killing viruses—far less effective than UVC,” Brenner said. He mentioned one 2006 paper from the FDA’s Center for Biologics Evaluation and Research that showed while UVC light efficiently kills SAR-CoV-1 (the virus that caused the 2003 outbreak of SARS), UVA light does not.
“Finally, I have some concerns about safety of the lining of lung exposed directly to the UVA light, without any protective layer of dead cells, which is typically the case with external exposure to sunlight,” Brenner said.
They are touting it for potentially cleansing bacteria from your colon. It might
work for that. Hasn't been FDA-approved, but this problem seems to precede Drumpf's infamous attempt at hack medicine.
They themselves say they doubt it could work to treat COVID-19, and are not recommending their device for that.
I tend to think the skeptics are correct, UV-A (what this device gives off) inside your lung won't do much, and could be harmful. BTW, I haven't even dealt with the minor matter that inside the body, there is no quick and easy route from your colon to your lungs.
Well, maybe inside Trump.
UV-C inside your lung might kill the virus, there's just the problem that fairly quickly it will also kill you.
