Notes:
1. The dominant wavelength, ld, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the
device.
2. The radiant intensity, Ie, in watts per steradian, may be found from the equation Ie = IV/h
V
, where IV is the luminous intensity in candelas and h
V
is
the luminous efficacy in lumens/watt.
