Abstract
Abstract A portable light having a U-shaped body and an elongated reflector supported on the body providing a space for batteries between the reflector and the body. Two lamps are supported on the reflector providing a flood light and a lens is supported on the body over the reflector and the lamps. Two cup-shaped end caps are supported on the ends of the light and one end cap has a frusto-conical shaped reflector integrally attached to it, and a lens closes the end of the cap having the reflector in it, and a lamp is supported on the reflector under the lens providing a spot light.
