1. A light fixture comprising:
a reflector comprising an upper edge and a lower lip, the lower lip having a front edge and a rear edge that cooperate to define an opening;
a light module disposed at least partially within the reflector and configured to generate light for delivery through the opening; and
a ballast coupled with the reflector and comprising:
a housing comprising a front wall and a rear wall; and
a power module disposed at least partially within the housing and comprising at least one heat generating semiconductor component, wherein:
the front edge and the rear edge reside in a first imaginary plane such that the light generated by the light module extends through the first imaginary plane;
a second imaginary plane that is parallel to the first imaginary plane is disposed between the light module and the upper edge of the reflector;
the second imaginary plane intersects each of the front wall and the rear wall; and
the at least one heat generating semiconductor component is thermally coupled with the rear wall at a location that is above the second imaginary plane such that the light module and the at least one heat generating semiconductor component is disposed entirely on opposite sides of the second imaginary plane.
