Yup. LED sources are wonderful...UV or not.
Funny, when orange man said this back in April, people were aghast. What Trump didn’t tell people was that just before the pandemic really got into full gear a patent for a UV light medical device was established. It had nothing to do with COVID. A UV light is set atop a flexible tube that is then put into the nose or mouth and pushed into the lungs. Once in the lungs the UV light then kills whatever is ailing the patient in their lungs. Immediately banned by the press because OMBTDS.
Here are a couple of products that use UV light to kill bacteria in water: A UV light pen and a whole house UV light filter. The first is used for backpackers that might need it, for example hiking the Appalachian trail. The whole house filter is sold as part of a package in water filtration systems and is usually has a high degree of effectiveness. Filtering water is only one step to clean water, purification is the next. Some methods of purification include using bleach. Whut!?! Yes bleach (not the scented kind) has long been a go to to sterilize water. UV light is also an option amongst many. UV light has a long history of being used to kill bacteria. There are even hospitals that have UV lights at their entrances. Some think it is just a cool lighting effect until you find out what it is really for.
Whatever you believe about UV light, it has been an effective killing tool against those invisible creepies. If only we could use it on Pehosi, Schumer and others as a bacteria that we would like to get rid of.
Black light matters.
Bleach hasn't been used to sterilize water on a mass scale for a hundred years. City water supplies are sterilized with gaseous chlorine (although that "does" react with water to form hypocholorous acid and hypochlorite...which is the active part of bleach).
As long as you have enough intense UVC light, it is effective for surfaces and air particles but many of these gadgets aren’t powerful enough. You really need a xeon powered high wattage light to do an effective job.
Here is one that works:

I was wicked sick in January/February. All the worst covid symptoms and more.
People I know who have been diagnosed recently have mild cold and well within a couple of days.
Do you think it has mutated A LOT so that it is not very lethal?
Yup.
Two points.
1) Way before COVID I purchased a SteriPEN Sidewinder. Part of my SHTF prep. Fill the one litre bottle. Attach to unit. Turn the crank for 90 seconds. UV light kills the bacteria.
2) Years ago my Doctor sent me to a specialist who decided to shop vac my lungs. I was asleep for the procedure. I did note he was going to thread a long flexible tube down my throat. Said tube had a light and camera to guide his work. I imagine they could throw a UVc light onto the tip of that tube!
It may have attenuated. We are certainly much better at treating it as well. honestly the cases have dropped so far that we are not seeing a lot of it anymore.
Well you are way out of touch with reality. Bleach is still used today as an ingredient to store water not just in the prepper society. Depends on the city. Gaseous Chlorine is not the only sterilization chemical cities have been using. Some cities use something similar to chlorine and I can’t think what the name is right off the top of my head. It is not chlorine. But then again household bleach is comprised of approximately 5% to 6% chlorine.
In my examples above I gave the example of a UV Light in the form of a pen light. This is a single user use. The other example I gave a whole house filter UV light. A typical household comprises between 4 to 6 people on average. So where in the examples do I even hint at “mass scale” sterilization? City water is actually not preferable to be drunk as the cities add additional chemicals that are potentially hazardous to mas scale health of its citizens. I would rather filter, purify and use an UV light filter from a well that has been deemed potable after an extensive water test than drink water from the city. The city I live in right now has a water hardness level over 30. I filter, purify and sterilize my city water before I even pour it into a glass to drink or in a pot to cook with. I also use a 3-chamber reverse osmosis system for all drinking water after I have filtered, purified and sterilized the water me and my family drinks and cooks with. So go ahead keep touting city water. Blah! Bah!
1000bulbs.com told me last spring that it does not.
2 doctors at my church told me it does not
it is great for bacteria and other bugs but does not work against viruses
I see articles like this and they all include enclosed canisters for things that are held in place for long periods under UV light
that is not a common need.
I am talking about what the vast majority of people in the USA use....not niche applications.
1) You used to work for... means you don’t anymore. Could careless what you used to do. You don’t anymore.
2) you are talking mass application and my conversation began with single use and family application and even state a common household size was between 4 to 6 people.
3) I have to bubble my water (In addition to all of the above) for a couple of days to get most of the bleach/chlorine/fluoride crapola out of the water the city added before it is of any use.
4) Most water filtration, purification and sterilization is done after the city treats the water and it is because the city mass treats the water that individuals must do undo their treatment.
5) Bleach...guess what... has chlorine in it. OMG! So please go back to Dow to kill the rest of the world.
Uh, the knowledge I gained as a PhD chemist working in a major Dow division which produced and sold chlorine didn't disappear when I walked out the gate.
The fact is that you have obviously deeply bought into the anti-chlorine eco-propaganda. You are ignorant and un-educated on the topic. Bye...........
“Maybe I will try the bananna test with it.’
make sure your eyes are shielded ...

btw, ozone is NOT a good thing to breath ...
“Yup, just run the light over the banana, wait 10 days and see if it turns brown.”
ROTFLOL!
btw, you can speed up the results of the test by refrigerating the banana after exposure to the UVC light ...
That said, UV-C light in specially mde enclosed containers (boxes & bags) sold by the manufacturer to make it safe is fine for home use. I have one and use it to sterilize the N95 masks I bought just when the CV19 epidemic was startng.
A freezer will turn a banana black in nothing flat. As soon as they thaw out they start turning black.
It saves time when you want to make banana bread.
For UV light to be fully effective in sterilizing water, the water needs to be free of all particulates first, by being run through a good quality filter or three.
When light shines through water, each particle in the water creates a tiny shadow behind it, blocking the light from hitting whatever is in that shadow. Any little bugs, microbes, impurities, etc that may be in the shadow won’t get a dose of the UV.
Indeed it does. It's also interesting that sunlight helps your body manufacture vitamin D. Vitamin D also kills the COVID-19 virus. Coincidence?
