Our Mission
Why heilys® exists
The name heilys combines "heil" – in the sense of healing – with "lys," the Nordic word for light. For us, heilys means: healing light.
The name also describes our mission:
"We want to help people use light more consciously, live healthier lives, and reconnect more strongly with nature."
To this end, we research light, experiment with it, develop concrete lighting solutions from it, and explain how light can be used in a health-oriented way – in harmony with our body's needs, rather than against them.
This is how knowledge becomes a heilys® product
1. Question and explore
We begin with a concrete application and the question of which light parameters are suitable for it.
2. Develop and Measure
Spectrum, intensity, optics, light distribution, heat development and operation are developed and tested as a connected system.
3. Test and support
Functionality and defined quality parameters are checked before shipment. Instructions for use and personal support are part of our product offering.
