Home FAQ What's the CRI and why is CRI important...

What’s the CRI and why is CRI important in LED lighting?


The color rendering index (CRI) of a light source is a quantitative measure of its ability to reproduce the colors of various objects faithfully in comparison with an ideal or natural light source. In general terms, CRI is a measure of a light source's ability to show object colors "realistically" or "naturally" compared to a familiar reference source, either incandescent light or daylight.

Can’t tell the difference between the black and dark blue T shirt in your closet? Could be that your current lighting source has a very low CRI! Not all light is made equal; some light renders color better than others. Color Rendering Index (CRI) is the measurement of how colors look under a light source when compared with sunlight. The index is measured from 0-100, with a perfect 100 indicating that colors under the light source appear the same as they would under natural sunlight.

This rating is also a measurement in the lighting industry to help discern naturalness, hue discrimination, vividness, preference, color naming accuracy, and color harmony.



- Lights with a CRI that is measured greater than 80 are considered to be more than acceptable for most applications.

- Lights with a CRI that is measured greater than 90 is generally considered “High CRI” lights.
