Body: The body is precision machined uni body cast from premium grade aluminum bar stocks with a durable, natural Type III Class I hard anodized finish. Proprietary heat sinking design bonds the LED board directly to the uni body aluminum casing for direct heat dissipation. A Tempered Optical Glass lens delivers a 120 degree beam spread for excellent area lighting while the Glow-In-The-Dark (GITD) reflector helps you find the light in the dark. Inbuilt protection includes automatic step down from High to Medium, and from Medium to Low when battery capacity is low as well as battery reverse polarity protection. Carries via a removable stainless steel pocket clip or elastic nylon headband (included) for hands free illumination thanks to the right angle head design.
