Notes:
1. The luminous intensity, I
V
, is measured at the peak of the spatial radiation pattern which may not be aligned with the mechanical axis of the
lamp package.
2. The dominant wavelength,
O
d
, is derived from the CIE Chromaticity Diagram and represents the perceived color of the device.
3.
T
1/2
is the off-axis angle where the luminous intensity is 1/2 the peak intensity.
