Abstract
Abstract A collapsible light wand is formed from a telescopic tube assembly comprised of a plurality of overlapping translucent tube sections, the outermost tube section being attachable to the light end of a flashlight. A locking bar pivotally mounted to either the flashlight or to the outermost tube section may be swung over the ends of the tube sections when they are in the nested (retracted) position. A storage cylinder large enough to receive the nested tube assembly may also be provided, and is preferably attachable to the rear end of the flashlight for ease of carrying.
