A light assembly for use with a low voltage power source. The light assembly semiconductor photo-emitters are electrically in series with a higher forward voltage drop than the associated low voltage power supply. To provide the necessary voltage the light assembly includes a current regulated step-up DC/DC converter. The semiconductor photo-emitters that are electrically in series are in the form of a monolithic light emitting diode array with a plurality of light emitting diode elements electrically and mechanically in series with a conductive, rigid bond region between the cathode region of the first light emitting diode element and the anode region of the second light emitting diode element. The first and second light emitting diode elements may differ in band gaps to emit different colors, that are additive to a non-primary color, such as white.
