Bacteria-killing ultraviolet light fixture called the Indigo-Clean is able to wipe out those same dangerous pathogens while still being safe for patients or caregivers in a hospital – refer https://gizmodo.com/this-bacteria-slaying-light-fixture-is-perfectly-safe-f-1715961794.
Originally developed at the University of Strathclyde Glasgow, the Indigo-Clean fixture, commercialized by Kenall Manufacturing when switched on it emits high-intensity narrow spectrum—or HINS—light at a wavelength of 405 nanometers that’s outside the range of ultraviolet, which is harmful to humans.

Blue light — not including dangerous UV frequencies — kills MRSA, the multidrug-resistant staph superbug.
The finding comes from Chukuka S. Enwemeka, PhD, and colleagues at New York Institute of Technology. Their study was funded by Dynatronics Corp., which makes the blue-light device used in the study.
In earlier studies, Enwemeka’s team found that MRSA died when exposed to blue light that included part of the ultraviolet (UV) spectrum. Even though the total UV dose was less than that of a few minutes of sunlight, it would be safer not to expose humans to any more UV light than necessary.

Scientists have known for decades that broad-spectrum UVC light, which has a wavelength of between 200 to 400 nanometers (nm), is highly effective at killing bacteria and viruses by destroying the molecular bonds that hold their DNA together. This conventional UV light is routinely used to decontaminate surgical equipment (refer https://www.genengnews.com/gen-news-highlights/uv-light-that-is-safe-for-humans-but-bad-for-bacteria-and-viruses/81255478 for more information.
So, the researchers used a LED device that emits blue light not in the UV spectrum, and found it worked nearly as well. (refer https://www.webmd.com/a-to-z-guides/news/20090204/blue-light-kills-mrsa).

Blue light has been researched for decades and FDA approved for various treatments. There are no adverse side effects connected to the use of blue light therapy when it is used either short or long term. In study after study, no adverse side effects have been reported.
A few examples are Blue light therapy for Neonatal Jaundice and for Crigler Najjar Syndrome: Patients. Refer https://lighttherapyoptions.com/light-therapy/blue-light-therapy/ for more information.
The only valid risk of blue light therapy is over exposure of blue light to the eyes, or eye damage from the high glare of some devices. For these reasons, most products come with eye protection included, and you should always wear it.

Orb (refer https://revivelighttherapy.com/ ) is perfect for disinfecting the products you use often, clean rarely, and don’t want to spray disinfectant in. light peaks at 405nm and tails off in low intensities to UV-A and blue light. Medical studies have discovered something incredible about the 405nm light our Orb peaks at — it’s very effective at killing and inhibiting the growth of microbes, while still being safe for humans to use every day.

UV light kills bacteria – as referenced from https://uvhero.com/how-uv-light-kills-bacteria. .
Bacteria are a group of single-celled microorganisms that reproduce through cell division. Among other things, bacteria cause fermentation, diseases, and sepsis. The single cell property of bacteria makes it be destroyed or sterilized by UV light. Since the main form of reproduction in bacteria is through cell division, any alteration in the structure or segment of the cell can influence the cell division process.
Shortwave (UV-C) radiation has a potent germ-killing effect. It causes erythema and ophthalmitis (pink eye). Low-weight mercury release can produce this radiation. The nature and the impacts of this radiation and the application are described in the section bellow. Ultraviolet radiation with a wavelength shorter than 200nm is called vacuum UV.
UVC wavelengths are in between 200 and 300 nanometers, making them germicidal – meaning they are fit for inactivating microorganisms, for example, bacteria, viruses, and protozoa. This quality makes UVC energy an effective, environment-friendly and chemical-free approach to killing dangerous microorganisms in any condition; yet particularly in healing facilities that contain tranquilize safe superbugs including MRSA and C. diff.
