Any known uvc leds that can destroy viruses/bacteria? Seems like this form of like only comes in bulb form.
Not a good idea to use UV light for a hand sanitizer but hospitals use UV light to disinfect. See this: A room should be ventilated after UV disinfection, and people are suggested to enter the room half an hour later. Although UV is effective in killing the virus indoors, UV lamps should not be used to sterilize hands or other areas of skin, as the radiation can cause skin irritation.
A long time ago I had a college roommate who used UV light in chemistry experiments. He woke up one night terrified that he had gone blind from staring at chromatography plates under UV light. Fortunately it was only temporary.
If you put a virus on a LED it will be dead in 5 days.
Any LED will do. You don’t even have to turn it on.
Astrolux is testing out a UV-C version of the S43 currently to see if it`ll kill off virus`
you may kill any virus bacteria, but later have to deal with black skin cancer
That’s fine, as long as I dont get coronavirus
Just wash your hands for 20 seconds using soap and water.

Everlight uvc led. Just released. I didn’t look at voltage. Found another one on Ali but only at 6,12 and 24 volts. I can understand the desire to put this in an extra flashlight and have a little magic wand in your pocket. However there’s a lot involved. How close do you have to be, how long are you going to have to stand there over the surface(s). You are going to need proper eye protection. Also ledsmagazine has a few articles on UVC LEDs.
What to do if the virus wears protective glasses?
(sorry, it’s that time of the month).
There are so-called safe UV-C lamps and filters - where the air is flowing through the box with UV-C bulb or UV-C lights in suspended ceilings (inside) where they cannot be seen - basically, any other direct exposition to UV-C is harmful to eyes and skin.
The same principle works in UV-C water filters.
Unless that is the only available option (soap and water would be way better), I would not depend on it.
Also it is not good for eyes or skin.
There are battery powered UV-C lights but they tend to be fluorescent tubes, not LEDs.
Fingernail gel polish drying lights use LEDS (usually 50-100 of them) and LOOK like UV-C, though they may not be.
==update, they are UV-A
how a UV gel manicure works:
Having gel nail polish applied is actually a multi-step process. A special nail solution is applied to each natural or synthetic nail in as many as four to five coats.
After each coat is added, the nails are briefly exposed to a UV-A light inside a small box.

nail UV gel with UVC curing would be terrible for skin over time
UVC is ionizing radiation like X and Gamma Rays
You may joke ,
But what if the corona virus is wearing a mask packed full of toilet paper for extra protection?
A UV light is not a safe way to sterilize my hands after I have been in public.
and its not the inside of my car, nor the inside of my house that are actually the vector source of coronavirus
Here is a UVC device I use at home, but it is not for coronavirus vectors:
the source vector for CoronaVirus is other humans I come in contact with when I leave home. Mainly from their hands and moisture from their mouth.
I have alcohol in a spray bottle, in my car
I spray my hands before driving home
and I dont touch my face after I have been out of the house, before sterilizing my hands.
I have also stopped shaking hands with people.
fwiw
I googled whether alcohol kills corona, apparently yes:
“_Emily Landon, an infectious diseases specialist at the University of Chicago Medicine, said the CDC recommendation for hand sanitizers is based on the fact that *60% alcohol kills “all of the coronaviruses we know about.*_”
Gotta admit, that light looks pretty cool in purple 
they claim to got 254nm LEDs?
those will be a lot more effective than 275nm to kill biotic material (skin, eye, maybe Corona virus)
the factor from 285 to 275nm is about 5-10 times more deadly, not sure what then 254nm will be compared
If anyone is interested, here is a post I made about UV-C bulbs:
not sure how light can do the job though
what about shadows?

leds of 254 or lower, prbly not yet. tubes are plenty. 240nm and lower create ozone, it goes thru clothing and disinfects a lot more than just a surface, but you can’t breathe ozone, i mean you can but it is not good for lungs, you need to ventilate the room, but such light works the best.
