How LED Color Rendering Index (CRI) Affects Your Life

The Color Rendering Index (CRI) measures a light source’s ability to reveal the true colors of objects, with a maximum of 100. Sunlight has Ra=100.

Impact of CRI

Low CRI makes reds dull, blues grayish, and skin tones look unhealthy. High CRI (Ra above 90) makes colors vivid, food appetizing, and skin tones natural.

CRI Recommendations for Different Scenarios
