Notes:
1. The dominant wavelength,
λ
d
, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the
color of the device.
2.
θ

is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
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.
