Protection from airborne pathogens using eye and skin safe, 222nm Far-UVC
*Sorry, we can no longer send to Canada.
Suggested use:
Assuming no more than four hours of use in a single day, and an approximate room size of 9-12m², each lamp should be positioned no closer than 50cm away from a room occupant. The more widely the lamps are spread, the more air volume will be exposed. If there are children or pets present, the lamps should be placed well out of reach.

Description:
The germicidal properties of ultraviolet light are well established and have been in use for almost 100 years, but that effectiveness has always come at a price- the potential for eye and skin damage. Far-UVC, the portion of the ultraviolet spectrum that ranges from 200nm to 230nm is often described as “eye and skin safe” but is perhaps more accurately described as “safer”. There is still an exposure limit- just much, much higher than with other portions of the UV spectrum.
Because of its relative safety, Far-UVC technology has tremendous potential and has attracted companies engaged in dishonest, even dangerous, marketing practices. Selling lamps that are not filtered so emit at unsafe portions of the UV spectrum above 230nm, that are far too low powered to be effective, or that make inflated claims of efficacy- including that Far-UVC is comparable to wearing a well-fitted N95 mask (it is not) or a substitute for upgraded filtration and ventilation in buildings (it is not).
New Far-UVC guidelines are being developed, and new products are being brought to market. For now, the safest way to use Far-UVC is as an additional layer, and not change your behavior because you have access to Far-UVC. We all have to eat anyway- eating with Far-UVC is safer. We have to go to the dentist anyway- going with Far-UVC is safer. Children need birthday parties and playdates- and even with kids old enough to mask, those masks slip or can be dislodged. With carefully positioned Far-UVC, these activities are safer. But if we are going to take a long flight- having a Far-UVC device is not a reason to fly unmasked. Far-UVC is a useful layer on top of masking, and adds a measure of safety, but it should never be considered justification to unmask in situations you normally would wear one. (If you have trouble finding a comfortable mask, we recommend the CanadaMasq Q100.)
Early on in the pandemic, it was hoped that a single, small Far-UVC device could offer “near-field” protection- create a zone of light around a person that would destroy pathogens before they were inhaled. Devices- including wearable ones, were made and tested, but in the end, the math for a single small emitter, providing any near-field protection, just does not work.
Pathogens need to be exposed to a certain amount of energy to be inactivated- joules or power over a given duration. A single 3-watt, low-power Far-UVC emitter does not have enough time to inactivate airborne pathogens to a significant degree before they are inhaled. If you increase the power- and so shorten the exposure time needed, it is no longer safe to have the emitter immediately next to the user for hours or days at a time.
When using Far-UVC, our goal is to get as much power (joules) into air volume as possible without exceeding the daily exposure limits of the occupants- so you need to avoid “hot spots” created by high-wattage Far-UVC emitters. Diffusing lenses are one way to spread the light more evenly throughout a room; another is using an array of small Far-UVC emitters instead of one or a few large emitters- and that is what the Mini Far-UVC kit does.
The Mini Far-UVC kit is sold as a package of four battery-powered, three-watt Far-UVC emitters with a carrying case and USB charging cable. That is a total of 12 watts- the minimum that would have an effect in a small (9-12m²) room.
12-watts, for a few hours a day, is also a very safe dose of Far-UVC that people can be trusted to self-administer without professional UV meters and installation equipment or issues involving secondary compounds that might arise with fixed, higher wattage installations intended for continuous use.
The set of four emitters are intended to be placed throughout a small room to expose a large volume of air without creating hot spots of potentially high exposure. They are not sold individually because one, 3-watt emitter simply would not have any meaningful effect based on the data we now have. If anyone tries to sell you a single 3-watt UVC emitter as any kind of mitigation tool- you are being scammed. The data simply does not support it at present. Please do not split up the set or share individual units- they are designed to be used together.
The price for four Mini Far-UVC lamps is the same price as just one of the competing portable lamps of comparable power. At the moment, this Mini Far-UVC kit offers the lowest price per filtered watt of any battery-powered Far-UVC emitter. It is an imperfect solution- but during its 3000-hour operating life, it should offer a meaningful layer of additional protection and bridge the gap until we have more solid guidelines.

Great collaborative Twitter threads from Siyuan Wang, Mike Famulare, and Joey Fox on why near-field, low-wattage Far-UVC doesn't work (and so why we needed to increase the power output x4 and distribute the emitters to get any meaningful effect).

Let customers speak for us
Placed one of these in the bathroom where people use the space unmasked. Comes on with ease and stays on long enough to kill anything in the air after each use. Simple and effective!
Great package, works perfectly, good battery life, small enough to be portable, high quality everywhere, including the bag.
Solid construction. Well packaged. No damage etc. Easy to follow instructions. Everything met or exceeded my exceptions.
Purchased Lanterns to complement our computer fan boxes. Cost wise, each Lantern likely less than the cost of each box and filter set. About the size of an alarm system's motion detector. Shipping was quick. Packaging was solid. Great communication with company as well.
This device keeps my indoor ventilation at just the right amount. Previously, my ventilator would run continously which uses extra electricity and caused extra energy loss and dries wintertime air too much. Now, when occupants are in the house, the ventilator runs and as occupants leave, the ventilator turns off. Simple, great device!
We absolutely adore our set. It makes critical public interactions (medical apptmts) so much safer!.
So easy to carry and deploy. Sorry, no images due to privacy reasons.
Absolutely LOVE my torches, I am so glad I bought them! Super professionally packed, they are high quality and easy to use. I just took them along to a painting course as added protection in addition to my FFP3 and immediately felt a lot safer. I can highly recommend them!
The first set of Nukit Torch lights got so much use that I needed another set, so that each family member can use what is needed at different places! Additionally I purchased 2 Lanterns, to use in my house and at my workplace where colleagues frequently come in coughing and sniffing.
Also this time fast shipping and in my case no extra tax costs, great!
The Lanterns are easy to install, the motion sensor works great and the timer in it is clever and convenient.
I definitely recommend this light!
Nukit Torches + PC fan air filters + leaving windows open a little + CO2 monitoring = a safer small weekly coffee-hour gathering with friends when it has to move indoors for inclement weather. Sleek design, ease of use/charging, -and a great storage case for travel. The third party testing/certifications, Far UV literature citations, and clear, helpful usage guidance gives me confidence that I’m using a safe product to provide an additional layer of protection to friends and family when we’re together. 💙 Nukit’s torches!
Fantastic bit of kit. Had an initial issue with the soldering station but it was quickly changed and sorted out. Great improvement for my workflow! Great service too
Thoughtful, through packing. It's going to arrive safe. Easy to build, just purchased the recommended parts mentioned in the documentation. Looks nice and unobtrusive. You won't know it is there because it is so quiet. It's great to have the ability to easily swap out parts if they break, without having to replace the whole unit. I doubt that is going to happen anytime soon however since the recommended parts are of high quality. Thanks so much for making this kit available!
Good battery life, works as intended. Having 4 units makes battery management and storing units at different places manageable. Very happy with purchase.
Third party testing increases confidence. I’d like if the product came with a far UVC test card to ensure units working as intended, but they can be gotten easily.
Good construction, but I would not want to drop-test. A weighted “seat” or charging cradle option would be useful, and I would buy two. Hopefully a revision will make operation while plugged in (charge and operate) an option for places where use for long periods of time is needed (e.g., workspace.)
LED indicators can be slightly hard to read in bright outdoor sun, have to hold unit close to face.
Case is slightly too snug for my taste, and the inserts between units don’t “stick” inside as well as I would have liked. The box inner packaging holder was much nicer.
When I saw this product, I knew immediately it plugged a hole in my home protection. I have an elderly parent in my home and want to protect them from what folks bring into the house from outside.
Well made, esthetically pleasing in the packaging and design. Making a lot of use with them and couldn't be simpler to operate.
Almost 5 years into the pandemic and I have so many layers of protection in place that adding UVC seemed like a no brainer.
I’m used to dealing with the doubting Thomas’s so I also ordered a reuseable UVC Quantadose card from the online rainforest so that I can demonstrate to friends and relatives that it isn’t just pretty mood lighting.
Having the 3rd party testing and links to research all in one place on Nukits has also been super helpful and I really appreciate the amount of effort put into collating all the data so that we can make informed choices.
Listen to me, even if you know nothing about putting pc towers together or assembling electronics, you can do this.
I have an elderly parent and with not just the rise of COVID but an assortment of respiratory diseases and virus, unwanted to be proactive in preventing a disaster for my father and family. This product came highly recommended and has not disappointed.
It arrived meticulously packaged, better than a lot of parts and components I've ordered from mainstream brands. Plus it looks exactly as depicted in videos and on the website. High quality components and ready to assemble immediately.
You are given everything you need. Just follow the video and/or read the instructions on the website. Done in no time at all, easy to maintain and I've combined this with the CO2 switch sold separately so that I don't need to think about it, everything is automated.
I have a ton of respect for this engineering.
