Notes:
1. The dominant wavelength,
λ
D
, is derived from the CIE Chromaticity Diagram and represents the color of the device.
2.
θ
1/2
is the off-axis angle where the luminous intensity is 1/2 the peak intensity.
3. Radiant intensity, I
e
in watts/steradian, may be calculated 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.
