REPAIR OF FLUORESCENT LAMP ASSEMBLY
Two rows of fluorescent ceiling assemblies provide illumination for the editorial and photomechanical shelter. The five-
lamp rows are controlled by two switches mounted on the interior aft wall of the shelter to the left of the shelter door.
Each fixture consists of two halves, the upper half being secured to the shelter ceiling. The lower half which clips into the
upper half contains the ballast transformer, lamp starter, fluorescent tube and sockets and associated wiring. (See fig.
