1. A lighting module, comprising:
a heat sink, comprising:
a sidewall having a first opening and a second opening; and
a partition joined to the sidewall, the partition and the sidewall together defining a first cavity that is accessible through the first opening and a second cavity that is accessible through the second opening;
a LED light source, disposed in the first cavity and coupled to the heat sink, to emit light;
a driver module disposed in the second cavity and coupled to the heat sink, the driver module comprising:
a driver housing coupled to the heat sink and enclosing the second cavity of the heat sink, the driver housing defining a driver cavity; and
driver circuitry, disposed within the driver cavity of the driver housing, to supply electrical power to the LED light source; and
an optical assembly, disposed within the first cavity of the heat sink and directly coupled to the heat sink, to redirect the light emitted by the LED light source, the optical assembly comprising:
a cover lens removably coupled to the heat sink via a tool-less coupling mechanism and enclosing the first opening of the heat sink.
