CREE’S STANDARD CHROMATICITY REGIONS PLOTTED ON THE 1931 CIE CURVE (CONTINUED)
Note: Effective July 31, 2009, Cree began sorting XLamp XP Family White LEDs with the new chromaticity structure
for the CCT range 2700 K to 4300 K, as shown above, in order to provide more-detailed chromaticity information.
There are no changes to XLamp XP Family White order codes. Customers with order codes containing any of the chro-
maticity bins 5A, 5B, 5C, 5D, 6A, 6B, 6C, 6D, 7A, 7B, 7C, 7D, 8A, 8B, 8C, 8D will automatically begin receiving the
new chromaticity bins.
Please note that there is no change to existing inventory at Cree or at Cree’s distributors, so customers may not see
the new chromaticity bins for a period of time.
