Devices, systems and/or arrangements for the homogenizing of different colors of light, particularly improved devices, systems and/or arrangements for the homogenizing of wideband red light with non-red light are provided. A light-mixing diffuser cover overlies a red light emitter and a light emitter that emits light at a non-red light wavelength. The diffuser cover serves to mix red light and non-red light emitted from the emitters upon passage of the red light and the non-red light through the diffuser cover.
