S1 is a precision-engineered light therapy system that brings the qualities of natural sunlight indoors. It integrates full-spectrum light, infrared warmth and carefully regulated UV into one coherent system, designed for stable performance and long service life. Installed as a ceiling-mounted unit, S1 operates quietly and reliably as part of your home environment, delivering natural-quality sunlight throughout the day.
By providing light aligned with the body’s biological rhythm, S1 represents a long-term investment in how your home supports everyday health and function.
S1 is built for residential use with the same engineering standards applied
in professional care and wellness environments. It installs without renovation,
runs on a standard outlet and performs at an optimal distance of 2–4 metres.
The system integrates seamlessly into modern interiors and works across a range of private spaces:
Materials and mounting solutions are designed to work safely with common interior surfaces, including tile, stone, concrete, wood and laminate. Placement is guided to ensure stable performance and long-term reliability.
S1 delivers controlled, full-spectrum sunlight through coordinated elements:
Together, these elements support biological rhythm, daily energy and physical ease.
Stimulated vitamin D production is vital for immune strength, calcium absorption, and long-term bone health – deeply linked to cognitive function and disease prevention.
Improved blood circulation enhances oxygen delivery throughout the body, relieves muscle tension, and activates the body’s natural recovery processes.
Balanced melatonin levels help regulate deep sleep cycles, stabilise emotional wellbeing, and synchronize the circadian rhythm for improved mood, energy, and overall wellbeing.
We have spent decades engineering sunlight for human use. The technology behind S.1 is developed in collaboration with an international leading technical university, combining advanced Swedish engineering with research in light science and human biology.
Every home is unique. We begin with a personal conversation to understand your space, your routines and how S1 should be integrated. Installed once as a complete system, S1 is supported long-term to deliver lasting performance and value.
Transform your home sauna with an indoor sun. S1 recreates the presence of the sun at home, combining light and infrared warmth to support calm, vitamin D production and immune function.
Built for intentional routines. S1 integrates seamlessly into your home spa, adding light as a functional layer that supports recovery and healthy daily habits.
S1 brings sunlight indoors in its most refined form. Full-spectrum light, safe UV, and vitamin D.
