Claim 13:
14. A dual source light system, comprising:
at least one light source;
a supercapacitor;
an electronic circuit receiving energy from an external power source, and being electrically connected to the external power source, the at least one light source, and the supercapacitor;
a housing unit installed in an elevator cabin within a wind turbine, the housing unit containing the supercapacitor, the electronic circuit, and at the least one light source, wherein the electronic circuit distributes energy received from the external power source energy to power the at least one light source, and charge the supercapacitor using any remaining energy; and
a control system configured to control how the electronic circuit distributes the energy between the light source and the supercapacitor, the distribution based on whether the energy satisfies an energy threshold,
wherein, when the energy received from the external power source is insufficient to power the at least one light source, the electronic circuit draws energy from the charged supercapacitor to power the at least one light source for a period of time to allow sufficient power to be received from the external power source to power the at least one light source.
