A luminaire includes a frame defining an opening, the frame having first and second frame edges on opposite sides of the opening. The luminaire also includes a carriage disposed within the opening, the carriage having a front face and first and second carriage edges on opposite sides of the front face, and one or more light sources arranged on the carriage. The luminaire further includes a tilting mechanism arranged such that the carriage is tiltable in at least two directions within the opening, and wherein when the carriage is tilted in a first direction from the central position, the first carriage edge remains proximate the first frame edge; and when the carriage is tilted in a second direction from the central position, the second carriage edge remains proximate the second frame edge.
