ABSTRACT:
An explosion-proof fluorescent light fixture for use in hazardous environments, comprising a pair of fluorescent lamps each shielded by a protective globe and electrical contact containing end connectors at the opposed ends of the lamps and globes. The end connectors and globes form integral one-piece self-contained units and, in case of breakage or a globe, the entire unit of globe and end connectors can be easily detached and replaced simply the unloosening or re-fastening of bolts which normally secure the end connectors to the light fixture. The end connectors are provided with detachable end caps enabling a burned-out tube to be withdrawn and replaced.
