Apollo Command Module Block II Cabin florescent lighting assembly, measuring approximately 6 x 5 x 3, with a power connector on the reverse and mounting bracket incorporated into the top of the unit. In fine condition, with scattered dings and soiling. These lights were mounted on the Crew Couch assembly and along the cabin bulkheads. They provided sufficient lighting for general activity throughout the CM and offered secondary illumination of the spacecraft control panels in the event the integral panel illumination failed. An interesting, easily understood piece of Apollo spacecraft hardware.
