摘要:
A flashlight with a rotatable lamp head is provided. The lamp head pivots about two cylindrical coaxial electrical connectors. The lamp head includes a reflector having a concave curved reflective surface and two lamp elements therein. A focusing ring on the lamp head moves the reflector in the lamp head for adjusting the focus of the light produced by the flashlight. The flashlight also includes a series of fluid-tight seals to insure that the flashlight is waterproof and a one-way flapper valve allows release of gases produced by the batteries and prevents fluid from entering the flashlight. A battery charger is also provided to recharge a battery pack for the flashlight.
