Notes for Table 6 :

1. The 3-step MacAdam ellipse is segmented into two sub-bins, one above (3U) and one below (3L) the blackbody line, for products with a minimum CRI of 80. Products with a minimum CRI of 70

are only available in a single 3-step MacAdam ellipse (30).

2. The 5-step MacAdam ellipse is divided into quadrants (5A, 5B, 5C, and 5D) for all products.

3. Lumileds maintains a tolerance of ±0.005 on x and y coordinates in the CIE 1931 color space.
