A miniature flashlight comprising a barrel, tail cap, head, bulb holder, bulb and an electrical circuit. The bulb holder is positioned at one end of the barrel such that the bulb extends into the head. The head includes a parabolic reflector surrounding the bulb such that the rotation of the head relative to the barrel changes the focus of the flashlight beam. A rotary switch associates the bulb holder with the barrel to control opening and closing of the electrical circuit. Rotation of the head away from the barrel closes the electrical circuit. The head is not a part of the electrical circuit and its removal exposes the bulb for substantially spherical illumination. The head assembly is removable from the barrel for use as a base into which the tail cap and barrel is inserted to stand the miniature flashlight in its "on" condition, as a lamp.
