A light emitter device includes a submount with a top surface and a bottom surface, electrically conductive traces on the top surface of the submount, light emitting diodes (LEDs) arranged on the top surface of the submount in light emitter zones, with the LEDs being electrically connected to respective traces of the traces, a retention material disposed over the top surface of the submount in a form of walls which physically separate the light emitter zones, and encapsulants that are dispensed in respective light emitter zones of the light emitter zones. A least a portion of the plurality of walls of the retention material can comprise a translucent material, a reflective material, and/or a light-absorbing material. The LEDs are individually addressable to independently control an output of light from each of the LEDs to produce a specified light output.
