averaged LED intensity
illuminance averaged over a circular aperture of 100 mm² area normal to the LED's mechanical axis at a distance of 100 mm for CIE Standard Condition A or 316 mm for CIE Standard Condition B from the tip of the LED, multiplied by the square of the distance and divided by a unit solid angle
Note 1 to entry: A detailed method of measurement is given in CIE 127
Note 2 to entry: The geometric conditions CIE Standard Condition A and CIE Standard Condition B, which correspond to symbols
Note 3 to entry: The averaged LED intensity is expressed in candela (cd).
