KORRUS

Korrus is a light-and-health technology company built around a single premise: that artificial light should work in harmony with human biology rather than against it. According to its own materials, the company was founded on the belief that light should adapt to the body, and it describes a team of physicists, engineers, and data scientists who have spent more than a decade advancing the frontier of light and health. That research effort is said to have produced more than 500 patents, including work with Nobel Laureate Shuji Nakamura, the co-inventor of the blue LED whose discoveries underpin modern high-efficiency lighting. Korrus operates across two distinct but related fronts. On the consumer side it markets OIO, described as the first consumer-ready circadian light ecosystem. OIO is designed to align light with biology in real time, delivering the right spectrum at the right moment to support sleep, energy, mood, and cellular repair. The system currently centers on the OIO Bulb, a full-spectrum LED that automatically shifts its color temperature through the day, together with the OIO App for smart spectral control and the OIO Loop, a biological light sensor that reveals invisible wavelengths and helps optimize a space for health. On the commercial side, Korrus owns and operates Ecosense, a technology platform serving a global community of designers and architects that has illuminated some of the most iconic spaces on earth. The consumer proposition is framed around a problem Korrus states plainly: modern indoor lighting keeps the brain alert well into the evening rather than adapting to the body's needs. OIO's answer is dynamic white light that runs from candlelight-warm to daylight-bright, providing energizing wavelengths during the day and removing blue light at night so users wind down naturally, fall asleep more easily, and wake up rested. The flagship OIO Bulb is sold at a list price of $69.99 in multi-packs, with the OIO Sphere fixture at $149.99. Both use 9W LEDs rated at 800 lumens (60W equivalent), span 1500–6500K, run on 120 VAC, and connect over 2.4GHz Wi-Fi; the bulb is offered in A19 and BR30 shapes with an E26 medium screw base and a rated life of 25,000 hours. Korrus positions itself at the intersection of circadian science, public health, and lighting innovation, publishing news and research commentary alongside its product lines. Its customer messaging emphasizes everyday outcomes — sharper focus, smoother energy, no afternoon slump, deeper sleep — and its commercial arm extends the same spectral-engineering expertise into architectural and specification-grade lighting. The company presents OIO as "only the beginning" of a broader effort to engineer light for human wellbeing.

Korrus presents itself as a company founded on a simple but profound belief: that light should work in harmony with the human body. Its own account states that for over a decade its team of physicists, engineers, and data scientists has advanced the frontier of light and health, work that it says has earned more than 500 patents and included groundbreaking collaboration with Nobel Laureate Shuji Nakamura, the co-inventor of the blue LED. That scientific foundation is the through-line of the company's history as it tells it: research first, then products. The company's commercial expression of that research is Ecosense, a technology platform that serves a global community of designers and architects and that Korrus says has illuminated some of the most iconic spaces on earth. Ecosense represents the specification-grade, professional side of the business, where spectral engineering is applied to architectural and large-scale lighting projects. The consumer chapter of Korrus's history is OIO. Korrus describes OIO as the first consumer-ready circadian light ecosystem — light engineered to align with biology in real time, delivering the right spectrum at the right moment to support sleep, energy, and cellular repair. The system was introduced around a clear diagnosis of the problem: current modern indoor lighting keeps the brain alert well into the evening rather than adapting to the body's needs. OIO's answer is light that works with biology rather than against it, providing energizing wavelengths when performance is needed and zero blue light when it is time to rest. The OIO ecosystem is built from three components. The OIO Bulb is a full-spectrum circadian LED that automatically changes its light throughout the day to follow the body's natural clock, helping users wake up, focus, and wind down. The OIO App provides smart spectral control, automatically aligning light with the body from morning to night. The OIO Loop is a biological light sensor that reveals invisible wavelengths and helps optimize a space for health. Together they form what Korrus calls a complete circadian lighting ecosystem that transforms light into a daily advantage — sharper focus, smoother energy, and deeper, more restorative sleep. Korrus has continued to expand the OIO line beyond the original bulb, adding the OIO Sphere fixture, and it maintains an active news and research channel covering circadian science, public health, and lighting innovation. The company frames OIO as "only the beginning" of its effort to engineer light for human wellbeing, signaling an intent to keep extending both the consumer ecosystem and the underlying technology platform.
