ABSTRACT:
A battery powered flashlight includes a case holding a battery, lamp, reflector and an electric circuit including switch means for connecting and disconnecting the battery to selectively energize and turn off the lamp. The flashlight includes a lens supported adjacent an end or side of the case in front of the lamp and reflector forming a rectangular beam of light when the lamp is energized for providing a non-glare illumination of a relatively small rectangular area such as along a sidewalk or a stair tread. The flashlight may also include a second lamp and reflector at an opposite end of the case providing a spotlight and a switch for selecting between the spotlight and the area illuminating beam. The flashlight may include a carrying handle in the form of a bail which acts to operate the switch for initiating the rectangular beam of light or alternatively the spotlight. When the handle is in an open or carrying condition for supporting the flashlight, the case depends downwardly therefrom and when the handle is in a closed position portions of the handle provide protective covers for each of the lens and lamp combinations while the flashlight is not in use.
