Abstract
A housing for a light fixture includes at least one wall that forms a cavity and a light source housing portion, where the at least one wall includes a thermally-conductive material, where the light source housing portion is configured to receive at least one light source. The housing can also include a wireway disposed between the cavity and the light source housing portion. The housing can further include multiple heat sink fins that extend from an outer surface of the at least one wall. The housing can also include at least one air throughway that exposes at least a portion of the wireway between the at least one wall and the light source housing portion, where the at least one air throughway allows air to pass over the portion of the wireway, where the at least one air throughway is formed independent of the heat sink fins.
