Abstract: A luminaire capable of selectively directing light from a lamp therein generally upwardly, downwardly, and outwardly, the combination comprising an electrical housing having a generally downwardly directed socket adapted to receive and support a generally vertically oriented lamp, and having a plurality of coupling members positioned around the socket; an upper reflector, coupled to the housing, and having at least a first portion located to reflect light from a lamp received in the socket; at least one reflector module; at least one fastener for coupling the at least one reflector module to at least one of said plurality of coupling members supported by the housing in a selected location to reflect light emitted from the lamp in a selected direction; and a refractor coupled to and extending downwardly from the housing, substantially enclosing the socket, upper reflector, and reflector module, and transmitting light from the lamp to the outside of the luminaire.
