Notes:
1. θ
1
/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
2. The dominant wavelength, λ
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
/η
v
, where I
v
is the luminous intensity in candelas and
η
v
is the luminous efficacy in lumens/Watt.
