A lighting device comprises a heat sink, a housing mounted to and/or thermally coupled to the heat sink, a basket assembly attached to the housing, a solid state light emitter thermally coupled to the heat sink, and a baffle assembly attached to the housing. Also, a lighting device comprising a basket assembly and a baffle assembly. In some embodiments, the basket assembly comprises a first member defining a first opening, a second member, a space between the first and second members, and lenses in the opening and in the space. In some embodiments, the heat sink extends farther in a first direction in a first plane than a largest dimension of the housing in any plane which is parallel to the first plane. In some embodiments, at least one additional component (e.g., a power supply module or a junction box) is in contact with the heat sink element.
