is the o-axis angle at which the luminous intensity is half the axial luminous intensity.
2. Dominant wavelength, λ
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
/η
v
, where I
v
is the luminous intensity in candelas and η
v
is the
luminous ecacy in lumens/watt.
