Abstract: A portable lantern may include a body that extends from a bottom portion to a top portion, and a light source disposed on or within the body (e.g., within the bottom portion or top portion). The lantern may advantageously include motion detection capabilities included therein. As such, the lantern may further include one or more motion detectors disposed on or within the body. In an embodiment, 3 motion detectors are provided, and the body is generally triangular, with a motion detector positioned at each apex of the generally triangular body. The motion detectors may be operatively coupled to the light source and/or an alarm so that upon detection of motion within the vicinity of the lantern, either the light source illuminates (from an initially dark configuration), the alarm sounds, or both. A plurality of modes of operation may be provided, allowing the user to select a desired mode.
