Abstract
A flashlight includes a first or top section attached to a second or base section. The top section has one or more elements that are axially moveable relative to the base section, for focusing light. This movement may be achieved, for example, by having the top and base sections joined via screw threads, and by rotating one section relative to the other. One or more lenses are supported in the top section. An LED or other light source is supported on the base section. As the sections move relative to each other, the lens moves relative to the LED, focusing light from the LED. The base section has a housing forming a battery compartment for holding at least one battery. Contacts may be provided on the base section for charging the battery, without removing the battery from the flashlight.
