1. A method of manufacturing a light emitting component, the method comprising:

  • determining a color target for the light emitting component;

    preparing a phosphor material based on the color target;

    determining an initial amount of the phosphor material required to meet the color target for the light emitting component;

    providing at least one light emitting die attached to a substrate;

    disposing the initial amount of the phosphor material over the at least one light emitting die;

    performing the steps of;

    (i) comparing light emitted from the light emitting component to the color target;

    (ii) if the light emitting component is above the color target, removing at least some of the initial amount of phosphor material from the light emitting component;

    (iii) if the light emitting component is below the color target, adding phosphor material to the light emitting component;

    repeating steps (i) through (iii) more than once; and

    curing the phosphor material disposed on the light emitting component.
