Notes:
1. The dominant wavelength, λd is derived from the CIE Chromaticity Diagram referenced to Illuminant E. Tolerance for each color of dominant
wavelength is +/- 0.5nm.
2. The radiant intensity, Ie in watts per steradian, maybe found from the equation Ie = Iv / ηV where Iv is the luminous intensity in candela and ηV is
the luminous ecacy in lumens/watt.
