ABSTRACT:
A hand held flashlight uses first and second light bulbs and first and second reflectors to generate a spot beam for illuminating distant objects and a flood beam for illuminating objects that are near. The first reflector is a parabolic reflector with the first light bulb being positioned at its focus to generate the spot beam. The second light bulb is positioned within the second reflector to produce the flood beam. A diffusing lens can be inserted in front of the second reflector to provide the appropriate divergence for the flood beam. The spot beam is preferably oriented at an angle relative to the axis of the flashlight for ease of use. The flashlight is designed so that the spot beam faces in a forward direction and the flood beam in a downward direction.
