Canopy light system

A retrofit lighting system, comprising:

• a power supply assembly configured to convert an AC input voltage into a DC output voltage and to adapt the DC output voltage to a substantially constant current level to be defined as a regulated current;
• at least one distribution wire in electrical communication with the power supply assembly and configured to conduct the regulated current;
• and
• at least one respective luminaire assembly spaced apart from and in electrical communication with the power supply assembly, and configured to receive the regulated current from the at least one distribution wire, the luminaire assembly comprising:
• a low profile heat-dissipating frame comprising a top portion and a bottom portion, the bottom portion including a central indentation and a plurality of heat sink fins positioned between an edge of the central indentation and a perimeter of the frame, the plurality of heat sink fins distributed substantially equidistant from each other along the perimeter of the frame;
• and
• a light source in thermal contact with the frame;
• wherein the DC output voltage is about 12 volts or less.
