A wide-beam, indirect lamp assembly comprising an elongated lamp housing symmetrical about a vertical center plane (26) and transparent to the light directed downward and open at the top and including at least two fluorescent tubes disposed on each side of, and equal distances away from the center plane. At least one reflector is provided for each tube in the lamp housing near each tube, said reflector operable to deflect at least part of the light beaming upward from the tube. Each reflector (30) is made of a perforated sheet metal and comprises, in vertical cross section, a first, generally vertical section (32) on the side of the associated fluorescent tube (28) facing the center plane (26), a second, generally horizontal section (34) on the top surface of the associated fluorescent tube (28); and a third section (36), adjoining the second section (34). The third section (36) slants upward and away from the center plane (26).
