"WebIn addition to directional color calibration, spatially-averaged color quantities of LEDs integrated over the entire emission angles are available from the total spectral radiant flux measurement as described above. It is recommended that white LEDs be measured for spatially averaged values, as the color tends to shift with viewing angle. " - How are colors measured

How are colors measured

WebPut simply, the Color Rendering Index (CRI) measures the ability of a light source to accurately reproduce the colors of the object it illuminates. This is a seemingly simple definition, but there is a lot going on, so we'll help break it down into three parts. Part 1: Color Rendering Index (CRI) is a score with a maximum of 100.
