A lighting system including a track member and a lighting unit supported by the track member 14. The track member includes an elongate base for mounting the track member to a surface, such as a wall, frame, etc. A pair of arms 26 and 30 extend from the base 22 in a common direction and define therebetween a channel 34 for receiving the lighting unit 18. Rotationally interlocking members associated with each at least one of the track member and the lighting unit restrict rotation of the lighting unit relative to the track member when the arm is in a first position. Upon application of a threshold rotational force to the lighting unit, the at least one arm moves to a second position permitting angular adjustment of the lighting unit.
