Notes:
4. The dominant wavelength,
l
d
, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the
device.
5. Radiant intensity, I
e
, in watts/steradian, may be found from the equation I
e
= l
V
/h
V
, where l
V
is the luminous intensity in candelas and
h
V
is the
luminous efficacy in lumens/Watt.
6. For Figure A package type.
