1. The dominant wavelength is derived from the Chromaticity Diagram and represents the color of the lamp.
2. The radiant intensity, Ie in watts per 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.
3. he = jV / IF x VF , where jV is the emitted luminous flux, IF is electrical forward current and VF is the forward voltage.
