Various structures are provided that may be advantageously used in one or more illumination device designs. In one example, a lens is movable among a plurality of light sources to facilitate selection of which light source is used to provide light for the illumination device. In another example, electric power is provided only to the light source that is used to provide light for the illumination device. Rotation of a bezel of the light source can determine which light sources provides light for the light source and which light source receives electric power. |
