There is quite simply no finer, more rugged, reliable, and capable flashlight in the world than this one-issued as standard equipment to U.S. law enforcers such as FBI agents and sky marshals. The lightweight, compact, tough flashlight emits a brilliant beam of light without the bulk and weight of larger flashlights. Constructed without compromise in detail and materials, the flashlight emits 65 lumens that outshine D-cell lights, rendering power outages, foggy nights, storms, thick forests, dark basements, even caves easily visible and navigable. Two modes of operation allow for constant beam or squeeze-beam selection (squeeze beam produces light only when the tail cap is pressed and held for quick spotlighting without constant battery drain). Two lithium batteries (included) provide power to the light for a full hour of constant beam use, and can sit on the shelf for up to 10 years and still be ready when needed. The tempered, shatter-proof Lexan pyrex window at the front deflects kinetic shocks and impacts. The flashlight body is made from aerospace-grade machined aluminum and hand assembled to ensure adherence to exacting specifications. Type II anodized tactical Black finish. 5" L x 1 1?4" Diam.
