A chromatically variable light source includes a plurality of light emitting diodes which generate substantially monochromatic light at different wavelengths. The light source includes circuitry for selectively energizing one or more of the light emitting diodes and for controlling the intensity of the generated light. The light generated by the light emitting diodes is combined in a single light pipe and delivered to an output port for use.
