Notes:
1. The dominant wavelength, l
d
, is derived from the CIE chromaticity diagram and represents the single wavelength which denes the color of the
device.
2. The radiant intensity, I
e
, in watts per steradian, may be found from the equation I
e
= I
V
/h
V
, where I
V
is the luminous intensity in candelas and h
V
is
luminous ecacy in lumens/watt.
