ABSTRACT:
The invention is an apparatus that is an extendable articulated flashlight. The apparatus have an electric power source; a housing for the electric power source, where the housing has a base; a light generating device; and an adjustable extendable collapsible arm connected to the housing and to the light generating device. The housing can additionally have a compartment for tools and a handle. In the invention, the collapsible arm and light generating device have a combined weight that is less than a total weight of the housing and an electric power source if the electric power source is contained in the housing. The housing acts a ballast that stabilizes the light generating device, so that the adjustable extendable collapsible arm can be fully extended in any direction, and the light will retain its position.
