Notes:

1.  For AlInGaP Red, the thermal resistance applied to LED junction to cathode lead. For InGaN Blue and Green, the thermal resistance applied to

LED junction to anode lead.

2.  The dominant wavelength, ld, is derived from the Chromaticity Diagram and represents the color of the lamp.

3.  Tolerance for each color bin limit is ± 0.5 nm.

4.  The radiant intensity, Ie in watts/steradian, may be found from the equation Ie = Iv/hv, where Iv is the luminous intensity in candelas and hv is

the luminous efficacy in lumens/watt.

5. he = jV / IF x VF , where jV is the emitted luminous flux, IF is electrical forward current and VF is the forward voltage.
