A lighting device (10) comprises a generally tubular body (12) having a dry cell cavity (14) adapted to contain one or more dry cells (16) for powering the light, the body having a rearward end (18) and a forward end (20). A cylindrical translucent lens (38) is fixedly mounted to the forward end of

A lighting device (10) comprises a generally tubular body (12) having a dry cell cavity (14) adapted to contain one or more dry cells (16) for powering the light, the body having a rearward end (18) and a forward end (20). A cylindrical translucent lens (38) is fixedly mounted to the forward end of the body, and a lamp (32) is mounted to the body at or adjacent to the forward end thereof. The lamp is adapted to be electrically connected to dry cells contained within the body. A generally parabolic or cone shaped reflector (42) is slidably mounted to the cylindrical lens and located within the interior of the cylindrical lens. The reflector has an opening in the center thereof shaped to receive at least part of the lamp therethrough. The reflector is slidable in an axial direction (37) between an extended position in which the reflector is spaced away from the lamp and light emitting from the lamp shines through the cylindrical lens, and a retracted position in which the lamp extends at least part way through the opening in the reflector, and light emitting from the lamp is reflected in a forward direction by the reflector. Preferably the reflector is mounted to a sleeve (44) which is slidably mounted to the cylindrical lens. Alternatively, the cylindrical lens may be slidable on the lamp body, and the reflector fixedly mounted to the lens. The lens may have a rear end of lesser diameter than the forward end.
