Cost and greed go hand in hand, but even without greed, the cost of good UV lights is still very expensive. And isn't necessarily greed but cost effectiveness. They are expensive to produce and don't necessarily last that long. I am saying this as someone with just the experience of buying UVB bulbs for a pet reptile. The florescent UV bulb has to be replaced around every 6 months even if it is still producing light because the bulb breaks down in a way and produces less UV light. And testing that UV is being produced isn't practical. It isn't something that we can see, so it is better for the animal to switch periodically than to wait for it to burn out. And they are much more expensive than regular florescent bulbs.

Vox unfortunately missed a few very important points to UV. HVAC Enginner here. For the last 100 years UV lights have largely been mercury lamps which have their own health risks. LED technology is getting there, but it hasn't got to the point of commercial usage. I am also surprised how much they glossed over how HVAC systems for non-residential often use UV for coil cleaning and you can add lights more to clean the air. I guess they simply don't understand you can add this to the airstream of 100% OA system and provide relatively clean air for building occupants. Also, you STILL need filtration and standard is to go with at least a MERV-13 filter as a final filter before entering most spaces. This is a 7min video but the fact they didn't talk more than a few words in this aspect of air treatment is mind boggling.

Wavelength refers to the length of one period, Frequency refers to the amount of periods that pass in a certain time. The smaller a period is (short wavelength) the more periods fit in a second (high frequency), as you can also see in the formula. Small ("low") wavelength thus means high frequency, high frequency means high energy. "Low" sounds like "less intense", which makes no sense when talking about wavelengths.

The negative side would be that the materials used in those locations would probably deteriorate a tiny bit faster, meaning that corporations would be happy. That's the offset foe getting the benefits of the light. Since it would come with a timer, you could also just choose not to use it as often. Point made here on this date money will be made later.

Sometime interesting is during the pandemic we were manufacturing some LED UV lights for the military, and a strange thing happened we found when we shined a UV light on oil it lost its stickiness and fell to the ground. It was super odd. We were all just like "Did you know UV light did that?" Not sure an application for that but it was an interesting thing that we didn't know UV did. As soon as you removed the light the oil returned to being sticky. Kinda weird to see, I'm sure there is probably an application here, but we were just trying to disinfect surfaces.

We did have to be careful though since UV light is actually dangerous, but not bad for turning the lights on and off. The old oil when it fell looked like black water running down the sides of the machine, when the light turned off it resolidified again.

Low wavelength? Light is measured by its frequency. Does low wavelength mean low amplitude, a weak UV light? IIRC all UV-C is bad for you. There have been quite a few situations where people have inadvertently exposed to UV-C germicidal lamps instead of UV "blacklights" and suffered severe skin and eye damage.

There was a club owner who had a black lite on the dance floor. When that light burned out he replaced it, with a UV light meant for sanitation purposes only. UV-C. It liked just like the old light so he had no idea what he had done before the complaints started coming in. It was bad

The ICU in my hospital has UV lights in the bathrooms that automatically switch on when no one is inside. Dunno how much good it does (good thing I'm watching this video!) but it's pretty cool

That should be the standard tbh. Toilets were constructed without droplets and aerosols in mind. That’s dangerous in a hospital.

I watch resotoration channels that deal with yellowed plastics. It's nice to see the explanation behind the process.

I have a UV light phone disinfectant and a UV light toothbrush holder. I love UV I know fast-food and restaurants have UV light in the kitchen

That's probably not a UV-C light in the restaurant, but UV-B (does not desinfect) and it's purpose is to attract insects to keep them away from the food.

I wonder if it could be paired with better air movement and filtration. Put the lights inside the duct work where it won't expose people before improved filtration to filter out the ozone.

That’s what probably didn’t fit into this short video and wasn’t promoted by the company they’ve interviewed. If you ask scientists, that’s exactly what they’re saying.

Restaurants and fast-food use them in the kitchen. You might even see a blue light in the dining room area at some places.

Those are insect traps. The light attracts the insects and there is glue paper near it to catch them. They are not meant to sterilize the air

I'm down for having this at my house, where I can turn it on when I'm at work

Most hospitals and public buildings use a lot of stainless steel for commonly touched surfaces, but its not as effective as using copper. Copper just needs more polishing.

I hadn't realized the potential of far-UV light as a disinfectant until now. The possible side effects, such as ozone production, are definitely a concern that should be further researched. This could indeed be an important additional tool in our health safety toolkit.

Put them on airplanes and in airports. I get sick every single time I fly and it would slow any spread of a new disease from country to country.

Yes because the air before the flight takes off and during landing is at peak toxicity while onboard a plane.

It’s already used in airports, but not in airplanes. Airplanes have HEPA-filters, because they’re recycling air inside, but they’re rather small. Air quality levels are often bad around boarding, if you carry a CO2-sensor with you, it’s quite astonishing to watch. I highly recommend you to wear a well-fitting respirator. I’ll never fly again without wearing one. There’s always going to be sick people on planes and it’ll only get worse from now on.

This is why I have a set of Nukit Torch Far-UVC Lights as part of my mitigation toolkit, along with my Aranet4 and comfortable Trident valved P2 masks. Having multiple layers of protection and real time air quality measurements at my disposal gives me flexibility and lets me make informed decisions about how I want to manage risk in different circumstances.

I wonder how effective are the hand held wands people use to disinfect and does the light really have to be constant like those shown in the schools

Doesn't light reflect on surfaces? So, weren't those kids shown in the beginning of the video still in danger of developing cancer later in life?!

For now yeah, but the tech is evolving. Once it gets FDA approval you'll start seeing it much more often.

Can any microbiologists expand on the idea of viruses and bacteria mutating to become UV-resistant if the use of the techology expands, similar to the antibiotic crisis we're in today?

Great muisc at the beginning. Where is that music from?

Nice Work & Video 👍

This issue needs to go viral. It should have gone viral at the beginning of the pandemic, when scientists at Columbia had already done the research and if our country still retained anything like a WWII attitude we could have had air cleaners all over the place. Those who got in the way of this should be publicly shamed.

I've seen them in HVAC systems which seems like a good use (assuming ozone is being controlled).

I’d love to have this in treatment rooms in between patients.

They need something like that in schools now. My kids are constantly sick anytime they go to school and get around other kids. But when they’re home long period of time they don’t get sick basically ever really.

Just like in the game dying light where every door to and inside a safe zone has UV light bars. I’ve always wondered what the real world application could be and it turns out it’s not far off.

In UK hospitals during Covid we had multiple air circulators on each ward near the doors which drew air in at the bottom, passed it through a UV chamber and released the air at the top. These were running constantly, especially in isolation rooms where Covid patients were staying.

In the USSR, short wavelength UV irraddiation was one of the most commonly prescribed procedures. Kindergarten children were getting their throats irradiated a couple of times a week as a prophylaxis during the Cold season. A couple of minutes of 40 W/m^2 broadband radiation from a quartz mercury lamp per session. I have no idea whether there were any serious studies of safety and efficacy. Medical textbooks focused on planning how many lamps would be needed for a given facility, just matter of factly assuming that the procedure was an established staple in the medical toolkit. This is almost never discussed in the West, and only now there appear high profile studies of similar techniques based on 222 nm light.

Cool

imagine if they put them in our screens

airports would be another great place to have these, help slow down or even stop diseases from spreading as fast.

Went down the far-uv rabbit hole during Covid. Reputable far-uv bulbs are still way too expensive. Wish there was more awareness, studies, and money going towards manufacturing.

This smacks of the whole ultra clean environment issues. Allergies and autoimmune conditions could be tied to growing up in an ultra clean environments. Healthy people that aren't old aren't dying from every day illnesses. Maybe this is worthwhile in hospitals and care homes, but this isnt reqired everywhere.

It's more complicated than that, and still being researched. The level of contamination in our current environments can be harmful too. Doing this in restaurants could easily turn out far more beneficial than harmful, and if we figure out which exposures are beneficial (which is useful regardless of UVGI catching on) it might not be necessary to get them through inhalation. We used to drink water contaminated by sewage. That's far worse for public health than our autoimmune disease issue. We haven't tested air treatment at that scale, but it could be a similarly clear net benefit. Excerpts from doi: 10.1073/pnas.1700688114 > Measles and many respiratory diseases proved not to be protective against allergic disease, and, in many cases, even increased the risk > “The trouble is, as soon as you use the words ‘hygiene hypothesis,’ the word hygiene prejudges what the cause is,” says Bloomfield. To the public, “hygiene” is interpreted as personal cleanliness: washing hands, keeping food clean and fresh, sanitizing the home. However, because the hypothesis has been largely uncoupled from infections, the idea that we need to be less hygienic is wrong. Relaxing hygiene standards would not reverse the trend but only serve to increase the risks of infectious disease, says Bloomfield. The term “hygiene hypothesis” also fails to incorporate all of the other factors now linked to the increase in immunoregulatory diseases. > Early in life is the key: It is likely any intervention will need to be done by 3 or 4 years of age, by which time a child’s microbiome is established and the immune system has completed much of its training.

It could also be useful in other places where many people gather: classrooms, offices, stores, restaurants. You don’t know who they might be bringing whatever disease home to, and things like measles and covid are no joke even for healthy populations. But, I agree it’s not needed everywhere. At home, it would be both ineffective (more direct means of transmission are much more prevalent) and, as you mention, being too clean has its own issues (in addition to allergies, there are helpful microbes). Apply where appropriate, get vaccinated, wash your hands.

It would be interesting if yall did a deep dive into UV. I work in an industry with some lasers and a lot of UV light

Now I understand why we have UV lights in the dying light game 😂😂

I think it would be the best idea to utilize them in public schools and hospitals. They are the top areas where pathogens can really go wild if they are allowed to roam free. It really wouldn't hurt to give this a shot. It's "risks" are pretty tame and manageable compared to most things. They come with benefits. The thing that is probably important is trying to keep people level headed about this new stuff and it's probably not necessary for each household to think they need to invest in their own system.. It's probably better for mass gathering zones

Exactly what I was thinking. It doesn’t make much sense in a home setting where more direct transmission is the issue. But, in a classroom or office? Those measles statistics are fantastic for such a simple mitigation!
