Ultraviolet light can kill almost all the viruses in a room. Why isn’t it everywhere?::Can special lightbulbs end the next pandemic before it starts?
cuz it literally burns your eye holes
Might be a good idea though if you could pair it with timers/sensors so that it only turns on when people aren’t home or something.
Like a 1 hour disinfection every day while people are at work/school.
Don’t most virus just becomes useless on most surfaces after so long anyway?
I’ve got my house kitted out with quite a bit of intelligence. I’ve spent a lot of time and money getting it working right, and it still has issues with human presence among other things.
I would absolutely not trust any automated system with something like this. It’s like buying tools from harbor freight: anything that makes your life easier is fine but never buy something from harbor freight that you have to entrust your life to. Similarly, never trust an automation that has the potential to end your life.
I’m going to shill for LifX here and not get paid for it. I swear.
They already made smart bulbs that you can set a “cleaning schedule” on that uses UV light.
I don’t have any yet because LifX is expensive. I have 11 of their multicolor bulbs throughout the house, though. Bought those back when I had bachelor guy money.
I look at this the same way I look at problems I’m trying to solve at work: is this already an issue causing massive problems with how we go about our day to day operations, or is this something that might have some kind of improvement.
It’s a resource allocation issue. Sure, I can add some bulbs that kill some bacteria and viruses. But how expensive are there bulbs, and how much are we having to deal with the fallout from when someone gets sick? In the grand scheme of things, would spending ~$1,000 on light bulbs to make sure my kid doesn’t get sick (but not when in range of the bulbs…) be more beneficial than just putting that $1000 into their college savings account and learning how to deal with missing a couple days of class when the inevitable happens (which the bulb can’t protect you from anyways - you’ll get sick from other people no matter how many lights you have at home).
That thing looks terrible. t’s wifi controlled and you’re supposed to install an app to use it. And it doesn’t say anything about the UV wavelength or power (HEV=high energy visible light so I guess 9000K can be translated to wavelength). There is a pdf test report about its efficacy against a few bacteria species but nothing about aerosol viruses. I’ll pass.
Better idea, they turn off if you look at them and then when you look away they turn back on. Simple
Ive seen this at universities
Without bothering to read the article, I look forward to sunburning my retinas like im at a crypto rave.
To be fair, nobody complained about getting COVID from that event.
The article does mention the issue of safety and how to address it actually
And bleaching all materials in the room. And slowly destroying anything made of paper or plastic or wood.
Joke aside, looks like they’re using a higher bandwidth of light, 222nm compared to more common 254nm uv for medical uses. It doesn’t penetrate the skin or eyes sufficiently to cause damage.
But will it activate my transitions lenses so I look like a cool guy wearing sunglasses indoors?
What if, and hear me out,
What if…
What if… we just ran them when people weren’t in the room? 🤯
Crazy what happens when you can come up with your own thoughts instead of parroting reddit comments ad nauseam.
What if… we just ran them when people weren’t in the room?
This is already a thing in many hospitals, and has been used extensively even before covid.
And there are also UV systems that can be added to air ducts to kill off airborne pathogens as well. But they’re not cheap and not commonly used outside of medical facilities.
Lemmy users don’t respond well to reasonable criticism or facts.
Only toxic and stupid comments allowed.
This thing kills all living things so why don’t we bathe ourselves in it?
I chugged cleaning chemicals. Now my insides are dirt free.
Is UV light the best thing since fermenting alcohol?
I worked for a company that made a UVC light system for sterilization. The amount of safety you have to build in so people wont nuke themselves makes them hard to use.Also, the bulbs we used were delicate and had issues constantly.
This is the dumbest shit. It kills all kinds of stuff, not just bad viruses. Homes are covered in bacteria which you’ve adapted to and are helpful. Kind of like gut bacteria, but outside your body. Killing all of them isn’t a good idea.

I always thought these were pretty cool. I’m not sure how HEV compares to UV though, or if it even works
Because it’s great at killing things, including human skin. Seriously, my local gym has people practically sign their life away before letting them into a UV-A/B tanning booth. No way are you putting the even worse UV-C bulbs out in public. That’s how people got their retinas fried at a crypto conference in Hong Kong last year.
People think I’m nuts when I wear sunglasses on cloudy days, but my eyes hurt. Idk why they don’t hurt the same way sunny days, probably I don’t squint when it’s not so sunny.
Probably the scattering effect of the clouds. Instead of light coming from one direction, which you can angle away from to reduce intensity, the diffused light from the clouds is bouncing every which way. Which while making the intensity less, instead keeps it constant no matter where you face. I often wear sunglasses while driving on cloudy days for similar reasons.
Basically, looking at direct sunlight will obviously be more damaging, but diffused light doesn’t give you a break.
A bit of the old Ultraviolence, eh?

i imagine theres a lot of overlap.
Because disease walks around as a person and is all the government, police, and banks. Even the jury and consumers here in fast food land, why does no one kill them all and live here. There’s natural food, processed food, jobs, cigarettes, booze, pharmacies, clothing, internet, addresses, electronic stores, knock off stores, bong stores, strip clubs, casinos, and now there’s weed stores. Hospitals what do you mean Japan was like a hospital itself. All anyone did was health stuff preparing for sexual things, and some drug use, but cigarette smoking ruined it. They got that mad about it, and probably alcohol, someone must have faked drug laws existing. Somehow there’s some election system or court that ruins it all. Oh well we all behave and lay in bed like we were supposed to with these TVs
Oh yes and there’s disease added to the food/drinks to brainwash everyone into the parasite economics thing that’s them stealing and embezzling everything and acting with it. But nothing could go on without sanitation or narcotic use, these things wanted occupy someone’s brain and seek attention 24 hours a day in the same house as them.
We’d have to starve ourself while working or finding a job but everyone was self employed, celebrities, and or business owners, stock holders. Maybe shareholders didn’t have these issues. There may have been uv c light bulbs in public schools or outdoor street posts which is why they worked so well at pulling everyone’s mind out of disease banking systems, where the disease didn’t even start it. They were just on the money as in a virus or bacteria physically on it, and they were on cards that come in the mail with that as a way to track you. Seems terrible but it for sure ended identity theft and credit card fraud.
This thread might be the worst example of “I didn’t read the article, but I’ll comment anyway” that I’ve seen.

Yeah but ducks shouldn’t do that!!!
(I didn’t even read the headline)
Because the spectrum required (UV-C) to do so is harmful to humans and the environment. Putting it EVERYWHERE would cause all kinds of problems.
The article blathers on for page after page after page talking about technology is back in the '60s and '70s, an experimental technology using UV wavelengths that supposedly don’t bother humans. And systems that only point up in a room like the UV light isn’t going to get reflected into your eyeballs. I get the feeling the author doesn’t have much of a background and was really just trying to stitch a bunch of research together without really understanding most of it.
You can safely blast the shit out of central air ducts, but it doesn’t do anything for infected breathing viruses into the air sitting next to you or the people that touched the bathroom door handle.
I suspect if we see any real non biased studies come out of any of this equipment the difference will be close to within the error bar.
This is the most informed comment in the thread where it’s clear you actually read the damn article.
Some of this does appear to be due to a widespread misunderstanding about how droplets spread disease in the medical field. It was thought that UV light far enough away to be safe would also be too far away to be effective. At least, not without additional ventilation, but ventilation itself would help reduce the spread, and we don’t do that because it’s expensive. UV would be cheap.
Research conducted during Covid corrected this scientific misunderstanding, and UV may be effective without additional ventilation. Ozone effects still need to be studied, though, as well as overall effectiveness. It might be that the additional ozone causes a few hundred additional deaths, but with the tradeoff of thousands or even millions fewer respiratory disease deaths. That would be a worthwhile tradeoff, but we don’t know what those numbers look like.
There is a setting in most computer monitors and maybe televisions but depends on it, with del it’s a for sure thing that existed, but it’s controlled from a transmitter, it has to get really bad and be the last stand, which it’s getting there. All it does is emit uv c radiation in certain amounts it’s too make sure that it’s an actual person or an animal using the computer. Parasites do weird types of stalking and crazy amounts of conspiracies through stolen computers or computers at places that are left on and it unlocked. They’ll even install software and then sit in some random closet or place using the computer making websites or duplicating things that get sold. It’s weird we assumed they all just used one host.
The uv c light kills the parasite and or bacteria/virus that’s in a human form using the computer. An actual person won’t die from it (a virus or bacteria immediately dies or it severely damages them and it isn’t fixable) possibly even suffer vision loss, I could never stand extremely bright lights until experiencing the radiation I think I had an old dell latitude computer that emitted uv c in small amounts. But noticed that over the years I had trouble keeping my eyes open and couldn’t stand being outside, I used IGF and mgf in my eyes through eye drops 2 mcg a ml, to try and help my blurry vision which I assumed was caused by my eye lashes or could gunk build up in the eye. Eye drops help and did improve vision, my vision got bad but sometimes was like it wasn’t bad but didn’t know what from. Maybe high co2 levels or chemicals in the air. There is hgh for vision issues, that’s what regular doctors used for it. The same amount can cure hairloss just not sure about jintropin curing it. The methionine is important or the most important thing, but it may not be true or just requires more or longer time period to regrow. Ultra violet radiation may also cause hair to grow instead of fall out, male pattern baldness may just be a yeast infection and hair may also fall out from certain steroids but it doesn’t stop it from regrowing.
I slept great and felt very relaxed after the uv c couple second burn into the cornea or staring at the bulb directly or into it for a couple seconds and feeling the zap. It didn’t hurt but was like an electrical sizzle short out followed by feeling great and free.
But these are high strength made for sanitizing a room or probably hundreds of feet, but ultraviolet radiation could travel miles, it doesn’t stop it keeps bouncing off things, but the rays spread out as they move away from the light bulb.
They just may notice their overall sensation of the atmosphere or the world around them changes when the radiation hits their skin or eyes, not sure which. I wonder if daylight LED light bulbs emit small levels of uv c. Probably not but they could. Sometimes uv bulbs were the only white LED bulb that existed, they were on little microscope loupes and things.
At first I didn’t get into them because my skin was red only under the 6000 kelvin daylight bulb.
UV light kills almost all viruses because it’s ionizing EM radiation. So it also fucks humans up, xd. I mean just stay on sunlight naked for a day. Your body will be so happy. All the mutations from ionizing radiation would be great.
But yeah we life in a society where ppl is scared of Radiofrequency EM waves (non-ionizing), “dangerous cell phone towers, wifi dangerous”. That same people recomends staying long periods of time with direct sunlight contact without protection (yeah we need protection because sunlight spectrum has UV and higher freq ionizing radiation).
Sunlight healthy/radio waves dangerous, that is the most stupid statement ever.
Sunlight is beneficial in small dosis because of how we syntetise vitamins (as little as i know). But remeber if you are scared of microwaves, remeber that sunlight has much more higher freq(higher energy) waves.
