Notes:
1. q
1/2
is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
2. The dominant wavelength, l
d
, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the
device.
3. Radiant intensity, I
e
, in watts/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 the
luminous efficacy in lumens/watt.
4. Please refer to Application Note 1061 for information comparing standard green and emerald green light output degradation.
