An apparatus includes: a plurality of light emitting diodes (LED) of similar or differing wavelengths; a reflector for collecting energy from two or more LEDs into an approximately composite beam; and a housing for distributing this energy into a common aperture. A heat sink and electronic control for the individual LEDs is included. The LEDs have different color outputs and are selectively controlled to determine the color of light from the apparatus. In one embodiment there are at least two LEDs, at least two reflector cavities, a common combining cavity or zone, a mounting each of the LEDs within the reflector cavities and a housing. The LEDs are mounted on the heat sink And selectively driven to modulate the intensity of selected ones of the LEDs according the nature of the frequency bands in the driving signal, e.g. mixed color outputs according to the control of a musical signal.
