Abstract: A track lighting device includes a clamp assembly having a dual engagement mechanism for coupling to a track. For example, the clamp assembly includes a collar rotatable about a collar axis, and a cam follower having a cam-pin received by a first groove of a cam. The cam also includes a second groove and a first engagement member. The first groove translates a rotational movement of the collar and the cam follower into a linear movement along the collar axis to releasably couple the first engagement member to the track. The clamp assembly also includes a latch assembly having a second engagement member and a latch-pin in communication with the second groove of the cam. At least a portion of the latch assembly pivots about a latch axis based on movement of the latch-pin relative to the second groove to couple the second engagement member to the track.
