In some embodiments, a method of manufacturing a lighting system comprises: coupling a light source to a reflector, the reflector including a substrate having a first side configured to face toward the light source; and disposing an organic phosphor layer on the first side of the substrate. In some embodiments, a method comprises: determining target color characteristics for light produced by a lighting system of a first type; for each one of a plurality of lighting systems of the first type: (a) measuring color characteristics of light produced by the one of the plurality of lighting systems; (b) determining characteristics of a phosphor layer to be disposed on a reflector of the one of the plurality of lighting systems; and (c) disposing a phosphor layer having the determined characteristics on the reflector of the one of the plurality of lighting systems.
