An image-casting flashlight has a housing adapted to hold a battery, a battery-powered LED light source mounted on the housing and directed forward along an axis, and a holder sleeve axially displaceable on the housing forward of and relative to the LED light source. An image carrier, e.g. a slide or a mask, is fixed in the holder sleeve and axially aligned with the light source. An end piece on the housing forward of the LED light source and of the image carrier holds a lens. Thus axial displacement of the holder sleeve moves the image carrier relative to the light source and to the lens.
