Notes:
1. Indicates product nal testing condition, long term reverse bias is not recommended.
2. The dominant wavelength is derived from the Chromaticity Diagram and represents the color of the lamp.
3. 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 h
v
is
the luminous ecacy in lumens/watt.
