A light fixture having at least two tubular lamps as light sources serially arranged one behind the other in a light pipe, wherein between each two opposing contact ends of the tubular lamps electrically conducting compression springs are arranged, characterized in that a compression spring (5) is in contact with the outer, electrically conductive contact ends (4) of the outermost light tubes (2), the other ends of the compression springs being supported by the body (6) of the light fixture, in that electrically non-conductive sleeves (9) are disposed about cylindrical peripheral surfaces (8) of the contact ends (4) of the tubular lamps (2), the sleeves (9) being movable axially relative to the tube (3) and the surfaces (8) of the tubular lamps (2), which sleeves serve to maintain the spacing and symmetry, in that the light pipe (3) has at least one longitudinally extending light discharge slot (10), and in that the ends of the light pipe (3) are mounted in the light fixture body (6) so that it is rotatable about its longitudinal axis for changing the orientation of the light discharge slot (10).
