ABSTRACT:
A flashlight with a rotatable lamp head is provided. The lamp head pivots about two cylindrical coaxial electrical connectors. The lamp head also includes a reflector having a major parabolic reflective surface and a minor reflective parabolic surface. The reflector is configured so that the minor reflective surface is nested within the major reflective surface. The flashlight also includes a series of fluid-tight seals to insure that the flashlight is waterproof. In addition, a flapper valve is provided to function as a one-way valve allowing the release of gases produced by use of the batteries, and preventing fluid from entering the flashlight. A battery charger is also provided to recharge a battery pack for the flashlight.
