1. A method of manufacturing an illumination apparatus, the method comprising:

  • forming a non-monolithic array of a plurality of light emitting elements on a support substrate;

    measuring a combined spectral output for at least some of a first sub-plurality of the plurality of light emitting elements in a first region of the support substrate;

    aligning a first wavelength conversion layer with the first sub-plurality of the plurality of light emitting elements of the first region, the first wavelength conversion layer having a first spectral characteristic based on the measured combined spectral output from the at least some of the first sub-plurality of the plurality of light emitting elements of the first region;

    measuring a combined spectral output for at least some of a second sub-plurality of the plurality of light emitting elements in a second region of the support substrate; and

    aligning at least a second wavelength conversion layer with the second sub-plurality of the plurality of light emitting elements of the second region, the second wavelength conversion layer having a second spectral characteristic based on the measured combined spectral output from the at least some of the second sub-plurality of the plurality of light emitting elements of the second region.
