Yes, a high general color rendering index (CRI > 97) is our standard. However, lighting quality experts also monitor another specific parameter: the R9 value. This describes the light’s ability to accurately reproduce saturated red. And in this parameter, most standard LED fixtures dramatically fail, even if their overall CRI appears acceptable.
Why is the R9 value so critical?
A lack of red in the light spectrum negatively affects both perception of reality and our health:
- Unhealthy appearance: Human skin, lips, and cheeks contain red tones. With a low R9 value, people appear tired, pale, and unhealthy. Our light with R9 > 90 enhances natural skin tones, contributing to better social interaction and mental well-being.
- Unappetizing food: The color of food, especially meat, fruits, and vegetables, strongly influences our perception of taste. Deep red colors of strawberries or tomatoes are lost under poor lighting, making food look less appealing.
- Eye protection and regeneration: Scientific studies confirm that red and near-infrared components of the light spectrum have compensatory and regenerative effects on retinal cells. They actively help protect the eyes from damage caused, for example, by blue light from monitors and other sources emitting so-called harmful blue light.
Spectrasol: Full spectrum without compromise
While competitors omit the red component of the spectrum, we consider it essential. Our Sun-inspired technology guarantees a high R9 value because our goal is not just to illuminate, but to provide full, healthy, and visually comfortable light that supports your health, energy, and vitality.
