You really dont want to live in a sterile environment, you actually need some stimulation to your immune and other bodily systems. Most body stuff is like muscles including the immune system - when you regularly over load and stress them, thats the impulse to stimulate growth and evolving.

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 thing kills all living things so why don’t we bathe ourselves in it?

HipHoboHarold ,

I chugged cleaning chemicals. Now my insides are dirt free.

Is UV light the best thing since fermenting alcohol?

asdfasdfasdf ,

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.

OnfireNFS ,

I always thought these were pretty cool. I’m not sure how HEV compares to UV though, or if it even works

nutsack ,

cuz it literally burns your eye holes

Pyr_Pressure ,

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?

Better idea, they turn off if you look at them and then when you look away they turn back on. Simple

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.

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.

bitwaba ,

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).

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.

LuxAlmighty ,

Ive seen this at universities

Dead_or_Alive ,

UV light is regularly used on HVAC systems and water purification systems.

There are systems used in hospitals that are automated which will roll into an empty room and then turn on to disinfect the room. They are usually used in hospitals but I’ve seen them used in places like China during their zero covid crackdown on public transportation.

Some transit systems in China even converted a paint booths to disinfect with UV so they could drive buses through. All of which is probably overkill as prolonged exposure to sunlight will do the same thing.

Exposure to UV light that is intense enough to kill viruses within seconds is very bad for humans. I pulled the cover off a system I was taking marketing pictures for while it was turned on. Within a thirty to sixty seconds I could feel like I was getting a sunburn on my arm that was closest to the light. I wouldn’t want to risk a direct UV system turning on while someone is sleeping and burning them. As a result most systems are indirect and rely on a combination of UV and HEPA filters to disinfect airborne viruses.

There are other ways to disinfect surfaces. Bleach or chlorine is cheap, simple and won’t harm humans. Chlorine gas can be used to kill really bad viruses like anthrax. Chlorine gas was used to disinfect the Federal buildings that had been contaminated in the 2001 anthrax attacks. Many detail shops, rental car agencies and public transit systems in the US use Chlorine gas on vehicles to disinfect or more commonly remove nasty odors from vehicles. The gas can seep into all cracks/crevices and get into the HVAC system ductwork in ways UV light can not. If you ever get into a car that faintly smells like a pool, chances are it has been gassed recently to kill an odor.

DragonAce ,

IIRC, they have UV sterilizers for central HVAC systems. So while it may not sterilize surfaces, it will kill all airborne pathogens.

atthecoast ,

The UV there is mostly to keep the inverter coils free of mould. Air typically flows too fast to be meaningfully disinfected.

SlamWich ,

Jeez, every response in here is about it burning your eyes. Thing is, people aren’t in every room all the time. Have it set to a sensor, same as the lights, and you can quickly sanitize large spaces that are unoccupied. Elevators, airplanes, etc can be sanitized the second they’re empty. My FIL is a retired GE engineer working on this technology.

doggle ,

I’ve been in a restroom and had the lights turn off on me because a sensor didn’t detect someone was still I the room. I’d bet good money I’m not the only one. Sensors, presently, are either invasive or inaccurate. Or both.

piecat ,

Sounds dangerous

I have lights go out on me all the time at the office, just sitting mildly still. What happens if someone falls asleep in the room? Or worse a kid? Severe sunburn and possible blindness

JargonWagon ,

Or what if they’re black? I’ve read so many stories about sensors not detecting people simply because they have darker skin.

Jimmyeatsausage ,

I dont think the lights would be on the entire time the room was empty…

atthecoast ,

Better presence sensors exist, and are only used in such critical situations. These are based on radar and sense the chest movements of people.

derf82 ,

Have it set to a sensor, same as the lights

Given how often the lights go out at work while I’m taking a dump, this isn’t the best idea.

Jimmyeatsausage ,

Fiber, bro…fiber

Threeme2189 ,

So you’re saying his internet connection is too slow? I agree

And009 ,

Pulling shit with fibers could help the constipated too

Pyr_Pressure ,

It’s definitely easier to tell if something is in a room than it is to tell if nothing is in a room. And sensors still fail at that. Timers would probably be better, since you don’t need disinfection every time a room is used.

If you know the office building will be empty every day at 2AM have the lights do their work between 2-3 every morning.

SoylentBlake ,

The light can be tucked away into the HVAC. The light never needs to hit anyone. You got central heating/cooling? One light, whole building. It’s almost criminal this isn’t common.

And009 ,

That is… Genius, the light probably needs some time to work but the idea of disinfecting a at a central location can work well for indoor air.

But my sweaty mouse pad, and dust stuck on the floor would need another system.

AFKBRBChocolate ,

Ever noticed how stuff left out in the sun gets bleached out and doesn’t last very long? Imagine leaving your carpet and all your furniture out in the sun. UV light is very hard on stuff.

Who the hell thought that an NFT festival was a good idea and unprotected UV lights?

Maybe the organisers were exposed to gamma radiation lwhen they thought up the event.

Not necessarily agreeing with the article posted, but for all the people who clearly didn’t read the article:

www.nature.com/articles/s41598-022-08462-z

That’s just one paper I found searching for far-UV. Seems to be many more.

Again not saying it’s 100 % safe or anything, but it looks promising.

UV light is both: A. Damaging to eyesight. B. Invisible.

You won’t know how much damage you’re doing to yourself until the damage has been done. This is how you give mass amounts of people eye trauma, and potentially blindness.

jayandp ,

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.

PutangInaMo ,

Yo what?! You have a link about that retina destroying conference?

Gumus ,

theguardian.com/…/guests-bored-ape-event-hong-kon…

It was a Bored Ape event "ApeFest’ in November. They used harmful UV bulbs instead of regular black light for decoration.

PutangInaMo ,

That’s wild! Appreciate the follow up.

Sagifurius ,

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.

jayandp ,

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.
