The typical cone angle measures where the luminous intensity is
90%
of the peak value of intensity.This typical cone varies with
LED color due to different chip size and chip position tolerance.

Luminous intensity depends on the flux binning and tolerance of the LEDs. Please refer to the LEDs data sheet for more detail on
Flux binning and mechanical tolerance
Notes:
(3) The typical divergence will be changed by different color, chip size and chip position tolerance.The typical total divergence is the full angle measured where the
luminous intensity is half of the peak value.
(4) The efficiency value listed above is the total value of the whole lens model, the value depends on the total flux of the LED used. Luminous intensity depends on
the LEDs flux and its tolerances, for more details of LED flux, please check Cree data sheet at www.cree.com.
