With its famously superior light projection and rock-solid reliability, the rechargeable Lithium Ion powered INOVA X3R LED flashlight is built to sustain years of tough recreational or professional use. Its precision-machined, solid aluminum body has a high-grade anodized finish, and is impact resistant, shock proof, crush-proof, and water resistant. The patented optical system is protected by a stainless steel head, features a high-powered, 36,300 hour LED, and a machined aluminum reflector for optimal thermal management and beam projection. A patented 3-position end-cap switch conveniently activates constant and momentary high and low power modes, as well as lock out mode. The included USB charging cable is compatible with any standard 1A 5v USB output, including AC adaptors, DC adaptors, computers, and solar panels. Its mini USB port and charge indicator are protected under a water-resistant seal - simply twist the head to expose, and twist back once the flashlight is charged to re-seal.
