The lighting track has side walls that define a trough and ledges protruding into the trough. The adapter includes a first element, a first flange element, a second element, and a second flange element. The first element is designed to attach to a device that is secured to the ceiling structure. The first flange element is attached to the first element to engage at least one of the side walls and at least one of the ledges of the lighting track. The second element is attached to the first flange element and receivable within the ledges of the lighting track.

Abstract: A recessed lighting fixture including a housing having spaced apart generally vertical walls defining an interior and an open bottom end. The walls have generally vertical slots through them. The fixture has lip means for maintaining the bottom end of the housing against a lower surface of a ceiling. The fixture further includes a plurality of mounting members disposed on an exterior surface of the wall means. Each of these mounting members has a first end, an outwardly curved elongated body portion made of resilient material and a second end. The first end of each mounting member is attached to the housing near the bottom end of the housing. The second end of the mounting member extends at least partially through the slot into the interior of the fixture so that at least a portion of the second end is accessible from the interior through the open bottom end.
