Notes :
(1) Correlated Color Temperature is derived from the CIE 1931 Chromaticity diagram.
(2) Seoul Semiconductor maintains a tolerance of 7% on Intensity and power measurements.
The luminous intensity Iv was measured at the peak of the spatial pattern which may not be
aligned with the mechanical axis of the LED package.
(3) The lumen table is only for reference.
