ABSTRACT:
A diver's flashlight having a unitary case with a closed end and with a battery pack in said case seated against a spring. A connector strip is positioned in the case and provides spaced-apart contactor portions at opposite ends of the case. A removable barrel is in watertight threaded engagement with the case and is positioned over a reflector block with a halogen lamp mounted in a reflector in the reflector block. Threading the barrel onto the case overcomes the spring pressure and completes the circuit between the bulb and the battery pack through the connector strip to switch the flashlight on and off. A battery charging unit incorporates a removable charging head which replaces the reflector block and barrel for in-place charging of the battery pack of the flashlight. In a second embodiment the lamp is adjustably mounted in the reflector block permitting selective positioning of the lamp with respect to the reflector to focus the flashlight beam in conjunction with the switch operation.
