Abstract: A reflector assembly for replacing a fluorescent lamp from a multi-lamp fixture having a top wall and oppositely disposed end and side walls enclosed by a diffuser plate. The assembly includes a reflector member extending longitudinally between the end walls of the fixture and width wise between the top and side walls of a fixture. The reflector member includes a plurality of walls disposed at obtuse angles with respect to one another to reflect a substantial portion of the illumination received from a remaining source lamp to produce a lamp image under the center line of the removed lamp on the diffuser plate so that it appears that a complete number of lamps are provided in the fixture even though less than a complete number of lamps are employed.
