Abstract: A lamp including a two-sided source plate, a plurality of light sources, a lens, a diffuser plate, and a driver insulator is disclosed. One set of the light sources generates white light and is attached to one side of the source plate. Another set of the light sources generates colored light and is attached to the source plate's other side. The lens encapsulates the white light-generating set, and redirects that white light. The driver insulator and the diffuser plate are each in contact with the source plate's other side. The driver insulator, diffuser plate, and that side of the source plate define a light box region that contains the colored light-generating set of light sources. The driver insulator acts as a reflector, and the diffuser plate acts as a diffuser, such that colored light is dispersed from the light box region through the diffuser plate.
