What is CRI and how important in LED lighting?
CRI is Color -Rendering Index, it means to indicates how accurately a lighting source reveals to the true colors of people, clothing object and so on once compared with incandescent light or daylight.
For reference, the testing method for CRI only tests eight standard pastel colors, does not test highly saturated colors.
CRI is important to consider in the retrofit LED bulbs, we can match that to the CRI of the LED system which use to replace the older system.
To learn more about this and the more technical side of CRI, following quick reads:
