OIO Bar
Architectural Light.
Human Purpose.
Light has the power to reveal architecture, transform materials, and define how a space is experienced.
OIO Bar combines precision grazing and washing optics with advanced circadian technology, allowing designers to highlight texture, create visual depth, and support occupant well-being throughout the day, evening and night.
Architectural Lighting Reimagined
Built for beauty. Designed for people.
With the industry's broadest range of grazing and washing optics, OIO Bar provides exceptional flexibility for illuminating walls, architectural features, and textured surfaces.
Ideal For
Luxury Hospitality, High-End Residential, Corporate Lobbies
Wellness & Spa Environments, Restaurants & Entertainment Venues

Circadian Metrics
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.
We Don't Follow the Standard.
We've Raised It.
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
Light Affects Your Biology. Every Hour. Every Cell.
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.
The home is where restoration begins. Circadian lighting creates a warm, supportive environment that helps reduce evening stimulation, encourages relaxation, and prepares the body for deeper, more restorative sleep.
