ABSTRACT:
A luminaire includes a generally parallelepipedic housing with a square opening into which a reflector and lamp assembly can be inserted and fastened. The opening is square as is the reflector so that it can be extracted and rotated 90.degree. as a unit. The reflector has a parabolic concave reflective surface and a lamp with an elongated light source, producing a rectangular pattern which is rotated as the orientation of the reflector is rotated.
