Notes:
1. q
1/2
is the o-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 denes 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 ecacy in lumens/watt.
