The 222 nm Safety Game-Changer

Not all ultraviolet light is created equal. UV wavelengths 222 nm and above are effective for killing or destroying bacteria and viruses. But as with any human-proximal technology, safety is the difference. 254 nm to 257 nm wavelengths are effective, but they penetrate dangerously deep into human cells.

Eden Park technology separates a certain part of UV: Far UVC or 222 nm. And it’s that wavelength that initial studies shows to be both effective and safe for humans.* Eden Park technology (in flat panel, thin 222 nm UV lamps) may provide immediate relief in mitigating COVID-19 outbreaks in populated indoor spaces, including factories, submarines, aircraft carriers, planes, waiting rooms, restaurants and more.

It’s important to know that 222 nm UV light is not appropriate for direct treatment of people or for ingestion.


Tests show that Eden Park’s 222nm lamps could be more effective at killing the novel coronavirus than standard UV lights.**


Eden Park lamps do not contain mercury, making them a sustainable option.

long life

Eden Park lamps range from 2,000 to 6,000 hours’ worth of lifetime.

thin & flat

Eden Park’s modular design makes them perfect for tiling, providing uniform illumination of large surface areas. And they’re easy to clean.

*As with any disinfection approach, each specific application and fixture design should be created in consideration of all applicable health, safety and efficacy implications.  Eden Park has partnerships with fixture design companies that can assist in this process.

**Based on preliminary results gathered across five independent studies, the final results of which are forthcoming.


American Technology in Action

For the Global Good

Developed based on innovations by Dr. Gary Eden and Dr. Sung-Jin Park from the world-leading College of Engineering at the University of Illinois, Eden Park lamps are the result of years of research and engineering iteration, creating devices with specific wavelengths of UV light in a thin, flat format. This design opens the door for a wide range of commercial applications.

In the face of threats like COVID-19, our work-spaces and meeting places need safe, effective solutions that will allow us to return to a new normal. Eden Park’s thin 222 nm UV lamps, also known as Far-UVC, are made in Champaign, Illinois, for communities across the globe. They work to continuously disinfect spaces (air and surface) and kill pathogens over 100 times smaller than human cells. And unlike longer wavelengths, 222 nm cannot penetrate human skin. When deployed properly, it’s a safer way to use UV lamp technology, starting today.

A new Normal

Our businesses and communities need solutions that can bring us back together, safer and more prepared than before. If you’re ready to find out how Eden Park thin 222 nm UV lamps can address your business needs, contact us today.

A Scientific Community-Wide Effort 

All over the world, universities and labs are exploring Far-UVC. Dr. David Brenner, a pioneer in the use of 222 nm UV light for disinfection, has partnered with Eden Park in studies for the National Institute of Health and has released peer reviewed papers demonstrating results over the years. His findings, and those of other researchers, are extremely promising.

Eden Park offers a series of lamps that provide manufacturing and product solutions.

In the past, commercially available lamps were cylinders or tubes, making the illumination of large areas non-uniform. Our flat ultraviolet lamps are made possible through patented microcavity, microplasma excimer technology and enable more effective direct light onto surfaces.

In addition to our thin 222 nm UV lamps, Eden Park carries an assortment of lamps at differing wavelengths including 147 nm, 172 nm, 220-280 nm and 308 nm that address important needs across the commercial use spectrum. 

Eden Park lamps can be easily tiled to provide illumination of large surface area. These products can have various geometries, beyond square.

A Unique Design

Eden Park Illumination’s patented microplasma technology has been developed and honed over more than a decade. This enables each version of our unique flat, thin lamp to produce a specific wavelength of UV light that is ideally suited to a specific purpose.


OEM partners are designing Eden Park lamps into products for air and surface disinfection. For three years, our 222nm lamps have been utilized in materials analysis and identification. With our newer thin 222 nm UV lamps, Eden Park partners are designing products for:



Hospitals and Medical Offices, Including Waiting Rooms and Surgical Theaters



Military and Government Applications



Meat Packing Facilities



Factories and Distribution Centers



Aircraft Carriers and Submarines



Mass Transportation: Planes, Trains, Ships



Restaurants and Retail



Offices (troffers and downlights) and Meeting Rooms
