FAQ

What other parameters can be used to evaluate the color quality of light?


Apart from CRI, R-values and CQS, color consistency is also a measure of the quality of light. The color consistency can be evaluated at several levels as follows:

 

  • Consistency over time: Color shifts over the life time of LEDs.
  • Consistency between different products and batches: Color tone variations from batch to batch.
  • Consistency across the beam of light: Color shift across the beam of the LEDs.
  • Consistency between color specification in the datasheet and that seen when the LED is used.
