Eden Park Illumination

Eden Park Illumination is a lighting technology company in Champaign, Illinois that develops and manufactures microcavity (microplasma) plasma lamps, including flat, wafer-thin Far-UVC 222nm panels used for continuous disinfection of air and surfaces in occupied indoor spaces. The panels provide uniform output across their surface, are designed to fit existing standard fixtures, and are marketed as mercury-free. The company states its lamps inhibit a broad range of pathogens, listing SARS-CoV-2, influenza A strains H1N1 and H5N8, MRSA and other Staphylococcus species, E. coli, Listeria monocytogenes, Legionella pneumophila, Salmonella enterica, Clostridioides difficile, Candida auris, several molds and fungi, bacteriophages MS2 and Phi-X174, murine norovirus and monkeypox virus.

The company's technology originates from the Laboratory of Optical Physics and Engineering and the Holonyak Micro & Nanotechnology Lab (HMNTL) at the University of Illinois. Beyond UV, Eden Park has designed square ultra-thin (5 mm) planar lamps emitting a uniform soft glow for professional cinematography and videography, built from arrays of thousands of gas-filled microcavities in a thin dielectric barrier structure with an internal phosphor coating for high color rendering. It also produces flat, high-power ultraviolet-emitting microcavity plasma lamps made from fused silica, with more than 10 watts available from 4-inch by 4-inch (100 square cm) lamps, enabling applications such as water cleaning and deionized water production. Prior to the COVID-19 pandemic, the company's single product was an ultraviolet light used to distinguish real diamonds from imitations.

Eden Park Illumination, Inc. is incorporated in Delaware, headquartered in Champaign, IL, and registered federally as a contract and grant recipient (UEI UJEXGL9PNA97, CAGE 51WZ3) with primary NAICS code 335139, Electric Lamp Bulb and Other Lighting Equipment Manufacturing. It self-certifies as a Small Disadvantaged Business and reports fewer than 500 employees.

Founding story

Gary Eden and Sung-Jin Park co-founded Eden Park Illumination in 2007 to commercialize microcavity plasma ultraviolet technology developed at the University of Illinois, where both were electrical and computer engineering faculty members. Eden serves as the company's chief scientific officer and Park as vice president of science; Eden earned his doctorate from Illinois in 1976 and is now an emeritus faculty member. The pair also co-founded EP Purification, a startup in the university's EnterpriseWorks incubator that uses microchannel plasma technology for small ozone generators to disinfect water.

Business model

Eden Park manufactures Far-UVC 222nm lamp and ballast components and finished panels, and positions itself as a single-source partner that supplies components and engineering design support to companies integrating Far-UVC disinfection into their own products, alongside deploying solutions in end-user environments. It is also a registered federal contract and grant recipient.

Traction

As reported in the Wall Street Journal in August 2021 coverage of pandemic-era small business survival, Eden Park had delivered more than 1,000 of its disinfection lights after shifting focus in 2020, and grew from a 10-person company by about a dozen workers. The company's most recent federal award is dated September 1, 2025.

Latest developments

Federal registration records show a most recent award dated September 1, 2025, with registration activation in May 2026 and expiration in April 2027.
