Notes:
1. The dominant wavelength, λ
d
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, I
e
in watts per steradian, maybe found from the equation I
e
= I
v
/ η
V
where Iv is the luminous intensity in candela and η
V
is
the luminous ecacy in lumens/ watt.
3. η

where Φ
v
is the emitted luminous ux, I
