What does “CRI” mean, and why is it important?

215 views 1 May 20, 2022 Updated on January 25, 2025 zhouwei

“CRI” stands for Color Rendering Index. It is a measure of how accurately a light source displays colors in comparison to a natural light source, such as daylight.

The CRI value ranges from 0 to 100:

  • A CRI of 100 represents perfect color accuracy, where colors appear as they would under natural sunlight.
  • A higher CRI (e.g., above 80 or 90) indicates better color rendering and is preferred in applications like photography, art studios, or retail settings.
  • Lower CRI values may cause colors to appear washed out or unnatural.
