Pretty much since the start of the COVID pandemic, Naomi Wu has been working to bring affordable high-quality far-UVC lights - deadly against pathogens, harmless to humans - to market.
I missed the product release announcement, but it’s alive! The devices output 222nm UVC for ~$150 per emitter. Each emitter is good for between 8 and 10m^3 of germicidal environment.

Nukit Lantern 222nm Far-UVC Light
Nukit Lanterns are available worldwide*, with free Shipping and Handling. Continuous protection from airborne pathogens using eye and skin safe, 222nm Far-UVC Effective- Kills viruses, bacteria, and mold in the air and on surfaces within seconds. Affordable- Lowest price per watt of any filtered Far-UVC product. Eye and skin safe- Third-party verified, all lab results available for download. Easy to install- Extra long cables, simple power control. Quiet- Perfect for those who can't tolerate loud filtration systems. We have a temporary limit of 10 per customer to ensure fair distribution. We now sell to the US (sorry, no Canada sales by request of the Canadian government). About the Nukit Lantern Far-UVC Light: Far-UVC is a recently discovered form of ultraviolet light that, unlike most UVC, does not penetrate skin or eye surfaces and can be used safely in the presence of humans and animals to disinfect air and exposed surfaces. Far-UVC rapidly kills viruses, bacteria, and fungi, making it one of the most powerful and broadly acting tools ever discovered for reducing the transmission of infectious diseases and allergy symptoms. Pathogens cannot become resistant to it, and none exist that are completely immune to it. Extensive studies have proven Far-UVC safe for humans. Up until now, Far-UVC installations have cost thousands of dollars per room. Nukit has completely reworked the existing Far-UVC production toolchain and offers high-quality, third-party tested Far-UVC for one-quarter to one-half the price per watt of any competitor- putting this lifesaving technology within reach of ordinary consumers. The Lantern is Nukit's latest Far-UVC product. Although more full-featured Nukit Far-UVC fixtures are in development, the Lantern is an effective, robust interim solution. It was developed to meet the immediate need for a low-cost, safe, and effective far-UVC emitter for fixed installation in homes and businesses. Features Each Nukit Lantern uses a 6-watt, 222nm Far-UVC emitter and a high-quality optical cut filter to block any harmful UV light. The Lantern is powered by 12V DC using a standard 5.5mm x 2.1mm barrel jack and comes with a power supply, international plugs, and five meters of cabling- making placement away from electrical outlets easy and convenient. Each Nukit Lantern also comes with a state-of-the-art millimeter wave (mmWave) human presence sensor to turn the lights on when you enter the room and off when you leave- to save power and preserve excimer bulb life. Many Far-UVC fixtures have frustratingly low-quality passive infrared sensors built in that constantly fail to read human presence, turning off the lamps when you need them the most. Millimeter wave (mmWave) is effectively radar, far more sensitive and reliable, and by using it as a separate, optional module, optimal placement to detect room occupants and the longest possible emitter life can be assured. Don't want detection? No problem. Use it as a remote on-off button- or don't use it at all. You can connect the Nukit Latern directly to any outlet or smart-home management hardware. The Lantern features a ¼-20 standard tripod socket on the bottom, meaning it can be installed with standard studio hardware wherever needed. Nukit Lantern Installation Instructions Proven Effectiveness Due to variables such as optical cut filter efficiency and size, reflector shape, and emitter gas composition, the output of a Far-UVC lamp cannot accurately be determined from the input power alone. Many manufacturers use questionable math to support their claims with no real-world data. Pathogen load testing, done by a third-party lab in a sealed chamber, is the only way to truly verify the effectiveness of a given Far-UVC air sanitizing device. Anything else is just guessing and taking the manufacturer's word for it- with no penalties for exaggeration or even outright lying. To ensure effectiveness, Nukit contracts with a third-party laboratory to test its products in a hermetically sealed chamber against a SARS-CoV-2 analog- showing precisely how effective they will be at their intended use in the real world. There is no guessing, estimates, or claims without accompanying lab results—just proof. Modeling: This Computational Fluid Dynamic (CFD) model uses the data from the GB/T 18801-2022 Air cleaner Appendix H Virus Removal Rate (Human Coronavirus HCoV-229E) test, and the Nukit Lantern spectral data, to show exactly how four Lanterns mounted in the four upper corners of a room inactivate pathogens in the entire space. Suggested Use 6-Watt Nukit Lanterns in 30m3: Viral Inactivation % 2 Nukit Lanterns 74.66% 3 Nukit Lanterns 83.76% 4 Nukit Lanterns 89.07% 5 Nukit Lanterns 94.67% (Click links for lab results) Based on this data, we recommend that customers combine Far-UVC with a high-quality air filter like the Nukit Tempest in each room to handle particulates and install one Nukit Lantern per 10 cubic meters (353 cubic feet) of room size. If you don't have filtration, install at least one Nukit Lantern per 8 cubic meters (282 cubic feet) of room size. Even if you can't afford a very high level of inactivation, the lower the pathogen load in a room, the lower the chances of infection, and according to current evidence, the less severe that infection will likely be.
