Notes:
1. The dominant wavelength, λd, is derived from the CIE chromaticity diagram and represents the single wavelength which denes the color of the
device.
2. The radiant intensity, Ie, in watts per steradian, may be found from the equation Ie = IV/η
V
, where IV is the luminous intensity in candelas and η
V
is
the luminous ecacy in lumens/watt.
