1. A light emitter device component comprising:

  • a substrate comprising a ceramic material layer having a porosity of greater than 0% but less than approximately 15%, the porosity of the substrate being configured to produce a total reflection of visible light of greater than 95%, wherein a top surface of the ceramic material layer is disposed along a single plane, at least a portion of the top surface of the ceramic material layer having been modified by lapping, polishing, and/or another mechanical modification to have a reduced porosity compared to an as-fired ceramic body;

    one or more light emitter devices mounted on the portion of the top surface; and

    one or more electrical components mounted on the portion of the top surface by one or more non-metallic adhesive layers and electrically coupled to the one or more light emitter devices.
