Abstract

A flashlight includes a body with a head, the head having a central axis. A light source is coupled to the body and a lens assembly is rotatably coupled to the head. The lens assembly has a rotational axis and a plurality of filters offset from the rotational axis such that rotation of the lens assembly places different filters on the output side of the light source. The rotational axis of the lens assembly is substantially aligned with the central axis of the head.
