Notes:

•

Cree maintains a tolerance of ±7% on flux and power measurements, ±0.005 on chromaticity (CCx, CCy) measurements and ±2 on

CRI measurements. See the Measurements section (page 7).

•

Typical CRI for Cool White (5000 K – 8300 K CCT) is 68.

•

Typical CRI for Neutral White (3700 K – 5000 K CCT) is 75.

•

Typical CRI for Warm White (2600 K – 3700 K CCT) is 82.
