Notes:
1. θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
2. The dominant wavelength, λd, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the
color of the device.
3. Radiant intensity, Ie, in watts/steradian, may be found from the equation Ie = Iv/ηv, where Iv is the luminous intensity in candelas and
ηv is the luminous efficacy in lumens/watt.
