A variable focusing flashlight includes a barrel which has a battery source of power contained therein and a tail cap mounted on one end of the barrel and having a compression spring provided thereon for urging the battery source towards the other end of the barrel. A lamp base retains a lamp bulb adjacent the other end of the barrel and includes a stationary receptacle mounted in the other end of the barrel and having an axially extending through bore formed therein. A pair of conductors are mounted in the stationary receptacle such that one of the conductors serves to couple the battery source and a first lamp electrode and the other one of the conductors serves to couple a second lamp electrode and the barrel. A movable receptacle has a plate portion disposed between the stationary receptacle and the battery source and formed with an opening and an upward extension that extends slidably into the through bore of the stationary receptacle. A head assembly is rotatably mounted on the other end of the barrel and has a substantially parabolic reflector with an open tail end to receive the lamp bulb and which abuts against one end of the upward extension of the movable receptacle. The head assembly is controllably translatable along the barrel when rotated with respect to the barrel.
