ABSTRACT:
An arrangement for two side-by-side elongated lamps in a lighting fixture in which lampholders are alternately mounted on opposite sideplates or brackets of the lighting fixture. The lighting fixture has an inside dimension that is longer than the length of each lamp/lampholder combination by a length sufficient to prevent the distal end of each lamp from overlapping the exposed plug portion and the lampholder of any of the adjacent lamps. The lamps are tightly gathered, and are close enough together to simulate a hairline light source having an optical centerline coincident with the optical centerline of the fixture.
