Notes:

1. For options -xxRxx, -xxSxx, -xxTxx, -xxUxx, -xxWxx, -xxYxx, max forward voltage (Vf) is 2.6 V. Refer to Vf bin table.

2. The radiant intensity, Ie, in watts per 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.

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