Abstract
The present invention provides a collapsible lantern including a base adapted to house a power source, and a telescoping portion movable, relative to the base, between an extended position and a collapsed position. The telescoping portion includes a light source electrically connected to the power source. A switch electrically connected between the power source and the light source interrupts the electrical connection between the power source and the light source when the telescoping portion is in the collapsed position.
