ABSTRACT:
An attachment for a flashlight for changing a narrow beam light output into a wide beam output. A hollow three dimensional reflector intercepts light rays coming from the flashlight, and redirects such rays into a series of fan-shaped patterns measured in radial planes containing the flashlight axis. A small central opening in the reflector transmits some rays in the forward (axial) direction. The attachment is useful during camping trips for illuminating the space within a tent enclosure.
