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
= l
v
/
η
v
, where l
v
is the luminous intensity in candelas
and
η
v
is the luminous efficacy in lumens/watt.
