ABSTRACT:
A housing for a tubular lamp having a generally rectangular configuration with parallel side walls and end walls forming a box with an open top and bottom. The side walls provide a channel at a bottom end and an inwardly directed flange at a top end along their length. A V-shaped reflector having straight segments with horizontally turned end portions is resiliently inserted against each side wall where one of the horizontally turned end portions presses against the inwardly directed top flange and the opposite end portion of the reflector fits into the channel. The invention provides for quick assembly and change-out of reflectors depending on conditions.
