Abstract
The present invention relates to a flashlight having a casing, a light source and a lamp head with a lens attachment that can be displaced longitudinally axially relative to the light source in order to focus the emitted cone of light. The object of the present invention is to provide a flashlight that, on the one hand, enables the reflector to be displaced smoothly relative to the light source and, on the other hand, prevents involuntary shifting of the focusing that has been set. According to the invention, the flashlight has a clamping device for fixing the lamp head in a selectable longitudinal axial position.
