Korrus makes the OIO System, a circadian lighting ecosystem consisting of smart bulbs, a spectral-control app, and a light sensor that shift light spectrum through the day to support focus and alertness and remove blue light at night to aid sleep. The consumer products aim to align household lighting with the body's circadian rhythm.

Company profile

researched Aug 2026

Korrus is a lighting technology company that engineers hardware and software for biologically aligned, or circadian, light. The company says its team of physicists, engineers and data scientists has worked for over a decade at the intersection of light and health, accumulating more than 500 patents and collaborating with Nobel Laureate Shuji Nakamura. Its stated technology pillars are spectral agility (delivering wavelengths matched to alertness, sleep and biological repair), dynamic control (software that shifts color and brightness according to circadian timing across Day, Evening and Night modes), and product integration (maintaining consistent spectral output across devices and spaces).

On the consumer side, Korrus sells the OIO system, described as the first consumer-ready circadian light ecosystem. It comprises the OIO Bulb (available in A19 and BR30 formats), the OIO App for spectral control on iOS and Android, the OIO Loop, a diffraction-based viewer that makes the bulb's spectrum visible, and the OIO Sphere, a more immersive circadian luminaire. Bulbs use Bluetooth for setup and Wi-Fi for clock synchronization, scheduling and app commands; daytime settings emphasize energizing wavelengths while night settings remove blue light.

On the commercial side, Korrus operates Ecosense, which supplies architectural and specification lighting to designers and architects, and the group also includes the Soraa brand. Company materials state that Korrus technology has been deployed in circadian lighting installations in hospitals, schools and workplaces.

Founding story

Korrus states it was founded on the belief that light should work in harmony with the human body, drawing on more than a decade of research by its physicists, engineers and data scientists into light and health, including work with Nobel Laureate Shuji Nakamura.

Business model

Korrus operates a multi-brand lighting business: direct-to-consumer sales of OIO hardware (bulbs, Loop, Sphere) via its own e-commerce site with a companion app provided free, alongside commercial architectural lighting sold under the Ecosense, Soraa and Tempo brands through specification channels and independent lighting agent sales forces in U.S. and Canadian markets.

Product sales. Consumer revenue comes from online sales of OIO devices, including the OIO Sphere listed at $149.99, with the OIO App offered at no charge; commercial revenue comes from architectural luminaire sales under the Ecosense, Soraa and Tempo brands.

Traction

Korrus reports more than 500 patents and states that its technology has powered circadian lighting in hospitals, schools and workplaces, with Ecosense lighting used in prominent architectural spaces. The OIO consumer line is commercially available for purchase.

Latest developments

Korrus has introduced the OIO system β€” bulb, app, Loop and the $149.99 OIO Sphere β€” bringing its circadian lighting technology, previously used in commercial and institutional installations, to consumers.

β–ΈFull profile β€” market position, technology, go-to-market, geography, history, risks & controversies

Market position

Korrus is the parent group behind Ecosense, Soraa and Tempo Industries in architectural and specification lighting, and positions OIO as a consumer circadian lighting ecosystem distinct from conventional and general-purpose smart bulbs. Ecosense, launched in 2009, has consolidated several LED makers through acquisitions.

Korrus differentiates on circadian-targeted spectral engineering rather than general color-changing smart lighting: OIO automatically adjusts spectrum in real time to biological need and removes blue light at night, uses a replaceable standard-socket bulb instead of an integrated LED panel, and ships with the OIO Loop so users can visually verify the spectrum. The company also cites its patent portfolio and research lineage in LED and photobiology.

Technology

Korrus develops both the hardware and software behind spectrally tunable LED lighting. Its systems shift spectrum and intensity in real time across Day, Evening and Night modes: energizing circadian-targeted wavelengths during the day and removal of blue light in the evening and overnight to support wind-down and cellular repair. The company cites foundational work in photobiology, LEDs and human-centric lighting, more than 500 patents, and lineage tied to the developers of the blue LED and to lighting systems at Ecosense and Soraa. The consumer implementation adds Wi-Fi/Bluetooth-connected bulbs with app-managed scheduling and the OIO Loop, a passive optical accessory that visualizes emitted wavelengths as a spectrum.

Go-to-market

Consumer products are marketed directly from korrus.com with promotional first-order discounts and customer testimonials, supported by references to third-party circadian research from Harvard Medical School, Northwestern University and the NIH. Commercial products reach the market through the Ecosense brand and, following the Tempo acquisition, through independent lighting agent networks across major North American markets; trade press noted limited overlap between the Ecosense and Tempo agent forces, suggesting the brands would continue to operate with some autonomy.

Consumers seeking sleep, energy and wellness benefits from home lighting, plus commercial specifiers β€” lighting designers and architects β€” and institutional environments such as hospitals, schools and workplaces.

Geography

Headquartered in Los Angeles (Chinatown), California; Ecosense is also headquartered in Los Angeles and acquired subsidiary Tempo Industries operates from Irvine, California. Ecosense serves a global community of designers and architects, and brand agent coverage spans major U.S. and Canadian markets.

History

Ecosense launched in 2009 and expanded by acquiring rival LED makers: Lumium Lighting in January 2019, which was later folded into the Ecosense brand as a separate product category, and the assets of Soraa in March 2020, which was retained as a separate brand alongside the UV spin-off brand SCUVA. Ecosense raised debt financing from Silicon Valley Bank in late June 2020. The business subsequently came under Korrus, which in February 2022 acquired architectural lighting manufacturer Tempo Industries, its largest acquisition to that point. Korrus later extended its circadian lighting technology from commercial installations into the consumer market with the OIO system.

Risks & controversies

Ecosense, now owned by Korrus, was among Southern California companies with debt financing tied to Silicon Valley Bank, whose March 2023 collapse raised questions about repayment to an eventual acquirer of the bank and possible new loan terms. OIO bulbs also require Wi-Fi and Bluetooth connectivity for full functionality.
