Abstract
A lantern lighting device includes a base portion defining a user interface, an upper portion coupled to the base portion and having an upper cover, an energy storage device disposed within at least one of the base portion and the upper cover, a first LED and a second LED coupled to the upper cover and configured to provide a first and a second light output, a divider coupled to the base portion and the upper cover, and a controller. The divider forms a partition between the first LED and the second LED that separates the first light output from the second light output. The controller selectively engages the first LED in a first operation mode to provide approximately 180 degrees of illumination or that engages both the first LED and the second LED in a second operation mode to provide approximately 360 degrees of illumination.
