The Luminaires specification has a tighter color angular uniformity requirement than the color maintenance requirement. Is this an error? Follow

No. The Luminaires specification's chromaticity provisions detailed in the Correlated Color Temperature Requirements allow a 7-step MacAdam ellipse (Fluorescent, HID) or a 7-step quadrangle (SSL), but for the Color Angular Uniformity requirement for directional luminaires, the specification restricts chromaticity variation to 0.004 from the weighted average point on the CIE 1976 (u,v,) diagram.
