1. A high bay light fixture, comprising:
an electronics housing;
multiple heat sink structures attached to the electronics housing, wherein each heat sink structure of the multiple heat sink structures is adjacent to two other heat sink structures of the multiple heat sink structures; and
light sources attached to the multiple heat sink structures, wherein each heat sink structure includes a bottom wall and side walls that extend up from the bottom wall, wherein each light source is attached to the bottom wall of a respective heat sink structure of the multiple heat sink structures on a surface of the bottom wall facing away from the electronics housing,
wherein each heat sink structure is spaced from other heat sink structures of the multiple heat sink structures that are adjacent to the heat sink structure, wherein the bottom wall of each heat sink structure is spaced from the electronics housing by at least a height of a side wall of the side walls of each heat sink structure, and wherein (a),
the side wall of the side walls of each heat sink structure includes a hole for routing an electrical cable between the electronic housing and the light source attached to the heat sink structure, or (b),
the multiple heat sink structures are made from aluminum sheet metal.
