The original tactical flashlight by inventor and designer Ralph Osterhout, the first light to have a battery life indicator. These lights have been dropped from a 7 story building, run over by an 8-ton dump truck and operated from the top of Mt. Everest to 2,000 feet (600 m) below water, whilst surviving the abuse. The flashlight assembly was featured on the TV program How Its Made.
