Farbwiedergabefähigkeit

Farbwiedergabefähigkeit, often translated as Color Rendering Capability or Color Rendering Index (CRI), describes how accurately a light source reveals the true colors of objects compared to a natural light source like sunlight. It is a crucial factor in evaluating the quality of artificial lighting. A high Farbwiedergabefähigkeit means that colors will appear vibrant and natural under the light. Conversely, a low Farbwiedergabefähigkeit can lead to distorted or muted colors, making it difficult to perceive true hues.

The Farbwiedergabefähigkeit is typically measured on a scale from 0 to 100. A CRI of 100 indicates a perfect match with the reference light source, meaning colors are rendered identically. Lower values suggest increasing levels of color distortion. For general applications, a CRI of 80 or above is generally considered good. In applications where accurate color differentiation is paramount, such as art galleries, photography studios, or retail environments selling colored goods, a CRI of 90 or higher is often preferred.

Different types of light sources, such as incandescent bulbs, fluorescent lamps, and LEDs, vary significantly in their Farbwiedergabefähigkeit. While incandescent bulbs generally have a high CRI, they are inefficient. Modern LED technology has made significant advancements in achieving high CRI values while maintaining energy efficiency. When selecting lighting, considering the Farbwiedergabefähigkeit ensures that the intended visual experience and color accuracy are achieved.
