LEDs are not manufactured like typical semi-conductors using lithography. They are grown on a substrate where tolerance is difficult to maintain. LEDs Vf can range from min to max on a single wafer. | |

| Nov 11, 2017 at 1:07 | comment | added | Misunderstood | This is not true: "The diodes in the same package are so closely matched from the same source process that the difference in their VF is infinitesimal". OSRAM paper says: "tolerances and material properties, Vf can vary between LEDs even if they are from the same wafer. " | |
