A surface mount luminaire includes a housing assembly formed by a light source housing and a housing cover that are removably coupled to each other. The light source housing includes a recessed structure that defines an inner cavity. The inner cavity houses a lighting assembly that is configured to emit light to an area that is to be illuminated. Further, the light source housing defines a second cavity that is disposed external to and around the recessed structure. The second cavity is enclosed by the housing cover and houses electrical components associated with the luminaire such that the electrical components are inset within the housing assembly of the luminaire. Further, the luminaire includes one or more gaskets that are coupled to the housing assembly to provide a seal that is configured to protect the one or more components disposed in the second cavity from environmental elements.
