Luminous Ceiling Panel Engineered for Circadian Impact
OIO Plane
Light Is Not Neutral. It’s Not a Utility.
Humans Are Biological Beings.
Our Bodies Respond to Energy, and Light Is Energy.
OIO Plane is the first circadian fixture engineered to disappear into the building and work for the body inside it.
Health-First Illumination
OIO Plane delivers circadian-supportive light, energizing alertness during the day and protecting restorative rest at night.
Seamless Integration
OIO Plane blends seamlessly into the architecture through a refined stretch membrane illuminated from both sides, creating smooth, even illumination that automatically follows the natural progression of daylight.
Designed to disappear into recessed ceiling and wall applications, it delivers illumination without visible hardware, diffuser texture, or disruptive fixture lines.
Minimal by design.
Architectural by nature.
Just light, where light belongs.
Engineered for Performance
OIO Plane combines precise spectral control with engineering optimized for continuous operation across wellness, hospitality, and residential environments.
Crafted to meet demanding architectural and performance expectations, it delivers visual comfort, seamless integration, and reliable long-term performance.
Purpose-built for modern environments.
Refined for everyday living.
Performance that feels effortless.
Into Biology
Most lighting metrics measure light output.
OIO measures biological impact.
By day, OIO delivers biologically active light that supports alertness, focus, and circadian entrainment. By evening, it automatically shifts to a low-blue spectrum that helps promote melatonin production and restorative recovery.
The charts show this transition through both BpL (Blue per Lumen) and mEDI, demonstrating high circadian stimulus during the day and significantly reduced biological stimulation in the evening.
Built For Every Environment
Engineered to bring the same standard into the home.
Well Building Leadership
Korrus’s Chief Scientist serves on the WELL Building Advisory Board. We are actively engaged with the International WELL Building Institute to elevate the WELL standard for circadian and biologically aligned light, ensuring tomorrow’s certified buildings deliver the biological outcomes today’s research already demonstrates.
Backed by Science
Maximum biologically active blue light during the day signals the body to maintain focus, energy, and cognitive performance, following the same alertness signals delivered by the sun.
By eliminating biologically active blue light at night, OIO Plane supports melatonin production and the body's natural sleep architecture, supporting deeper, more recoverable rest.
The full spectrum shift across the day keeps the body's internal clock anchored to external time, the foundation for hormonal balance, mood regulation, and metabolic health.
In healthcare environments, biologically aligned light has been shown to support patient recovery, reduce length of stay, and improve outcomes across acute and long-term care settings.
