Nukit UVC germicidal light vs traditional mercury vapour

This is not a sponsored video. I feel it's important that people should know about this evolving technology, and Naomi Wu is working on making it affordable.

The Nukit is a new style of germicidal light that uses a 222nm excimer lamp to create UVC light that can deactivate bacteria and viruses in the air of occupied spaces.

The 254nm wavelength of traditional mercury vapour germicidal lights is long enough to penetrate deep enough into the skin to cause sunburn effects and serious eye irritation (photokeratitis), and as such they can not be used in occupied areas.

The new 222nm UVC sources are considered safer to use in areas like hospital waiting rooms, as the shorter wavelength is blocked by the outer layer of dead skin cells and the moisture layer over your eyes.

You can find out more information about the Nukit light at Naomi Wu's website:-

Yep, I went to the hospital when I temporarily blinded myself with the first bulb. The pain was incredible. Like a knife stabbing your eyes. I still have a UVC bulb in my shed to prevent mold, however now I close the door and leave.

One potential downfall compared to its ozone-belching counterparts is that it doesn’t penetrate very far so if the critters decide to settle down and make things like biofilms and other nastiness it may have limited effectiveness. Still seems like a nice addition to an air purifier to keep things from becoming contaminated in the first place, which seems to be its indented use.

Oh wow. I've never seen 222nm UVC. I'm building a photoelectric project to show light knocking off electrons and this might be a wonderful improvement over the 254nm I have. Thanks!

One thing I've learned from this channel, if we were to normalize public use of this, dangerous knockoffs would be on the market immediately.

Marketing department must be proud of the product name.

but uvc tubes looked great in that HK nightclub!

254Nanometres is the ideal wavelength for erasing EPROMS.

Cool we have those lamps in our exhaust hoods over the Fryers and Barbecue at work🙃

Does the traditional UVC light damage other living things, such as plants? Does it damage things like fabric or plastic?

[mernokimuvek]

I experimented with a 16 W UVC tube and a 8 W plasma globe. The power was low enough that I didn't get eye damage. But still better to put it in a glass tube if you want to experiment with plasma for a longer time.

Do they both make ozone? Because thats my biggest concern with UV is that im trading safty from bacteria and viruses for cancer.

[ManWithBeard]

Not a bad plan. Most surfaces on the body that aren't covered by dead cells are indeed wet, so there's always a barrier. Must be a special type of glass that filters out the harmful longer-wavelength stuff (feels weird saying that...) because the contents of the bulb itself probably aren't very different. I wonder if there are downsides to this approach. It might have difficulty in deactivating bacteria on rougher or more porous materials.

Looking beautiful but cant see it for long time

[jonleiend]

So the second one is not strong enough to do anything?

[andrewwhite]

I’m liking it. Where does the money go?😂

[lafamillecarrington]

I find that quite scary - using even more damaging radiation in the hope that it isn't going to penetrate far enough to do any serious damage.

Right, right, right. I’m beginning to believe that my love daytime whites 6000-6500K are having an impact on how well I can see now. I was an early adopter of the new tech and when I bought my new place in Vegas in 2012 the builder/electrician installed nothing but the cheapest CFLs on the market and I felt like I was missing out on at least a 40% CRI degradation. Back then in 2012 a regular BR30 Phillips daytime white sold for $21 a piece, but they changed everything for me. In fact I missed so many punch items due to the dim lighting that I had to fix most of my punch items which was fine. My builders super tried to tell me that issues I pointed out is not something that they’d fix and they would answer back with “your issue is with an item that’s industry standard” That old saying “looks good from my house” mentality is fucking a lazy thing to say. Sorry I got distracted, anyways I finally got all my homes light CFL bulbs swapped out of service and I took my time getting the shitty CFLs recycled at a proper drop off. I love the higher kelvin whites, but I sometimes wonder that if I choose a lower kelvin 3500-500K (soft white) would my eyes feel better or the same. Clive talks about these UVC mercury bulbs won’t screw you up. That’s what any non suspecting consumer won’t know is if they feel irritated by the UV exposure get far away. I read this guys story where he needed a new fluorescent tube light for his lizards aquarium. He didn’t notice and the store owner notice either until he got home and quick swapped the bulb and then ate his food he picked up. Early morning he woke up and he realized he couldn’t open his eyes and they secreted ooze which welding his eyes closed real bad. His whole face was puffed out and swollen. That dude cooked a bunch of his DNA on top of all that. Scary shit. I have a few lights that have UVC lights in them but I’m over cautions with all that

Would the Nukit be harmful to dyes in fabric, or the fiber content, themselves?
Having something like that in a dressing room situation might be handy….

Can the Nukit be used for mold control?
