ABSTRACT:
A light is provided which includes a first, forwardly concave reflector member, a first, forward lamp spaced ahead of the reflector member, and a second rearwardly concave reflector member spaced forward of the lamp. The rear reflector member has a generally parabolic surface and the forward member has a generally arcuate surface. When the lamp is activated, its rays generally travel forward, are reflected off the second reflector member rearward onto the first reflector member, and then forward in a substantially parallel array to provide a spot light. A second lamp is located axially rearward of the first lamp and forward of the first reflector. When this lamp is activated, its rays travel generally laterally, strike the first reflector member, and then are reflected forward in generally random array to provide a flood light. Means are provided to selectively activate either or both of said lamps. In a further embodiment, the first reflective member has a spherical central portion and a parabolic peripheral portion.
