ABSTRACT:
An improved portable handlamp has a fluorescent lamp mounted in a lens assembly. A flexible elastomer handle mounted to the base of the lens assembly provides a cavity for receiving a ballast in an interference fit. The ballast is connected to the lamp holder by a bracket which also serve to mount the actuating switch in a manner such that these components form a frame permitting the user to grasp the handle and maneuver the handlamp.
