Perfect for everyday use by LE and Security Professionals and civilians, the XBT A6 Flashlight provides two output levels and more illumination than most other flashlights. Top quality components such as Aerospace Grade aluminum, a top quality polycarbonate lens, a regulated circuit, and a Cree XMLB LED provide superior durability, output, and run time. The XBT A6 is powered by six (6) economical AA batteries (included) and casts 629 lumens of light on High and 111 lumens on Low. Another bonus is that the XBT A6 can run at full power with just three batteries installed (note that run time is reduced by about 50%). Additional features include the crenellated bezel, an anti-roll rubber ring, and water- and impact-resistant construction for all-around dependability. Aerospace grade aluminum. 10.188'' long, 2.188'' diameter head, 1.44'' diameter body. Material: Aluminum.
