The perceived quality of a lighted space is greatly affected by the color consistency within the space; therefore, the consistency of individual luminaires’ output is crucial.
That’s where MacAdam ellipses play a role. Today, experiments conducted by physicist and color scientist David MacAdam in the first half of the 20th century help us understand the perception of slight differences between colors.
But how do MacAdam ellipses factor into LED lighting? We spoke with Reed Bradford, director of optical design and services at Eaton’s Lighting Division, about the correlation.
