## Abstract

A portable lantern light is configured to be operated in a range of selectable operational modes to provide flexible illumination solutions in both stationary and portable situations. The lantern light includes an elongated central body with a plurality of external longitudinal ribs, longitudinal channels positioned between a pair of external ribs, a lighting element residing within the channel, and a lens overlying the lighting element that acts as a primary optic. A power source that includes a battery cartridge is removably inserted within a receiver of the central body. The lantern light includes an operating mode selector assembly to control which lighting elements are illuminated during operation of the portable lantern light, and a luminosity selector assembly to selectively control the lumen output (brightness) of the lighting elements. The lantern light also includes a retractable stabilization assembly that can be deployed to stabilize the light on a support surface.
