Surefire KE2-T Turbo Scout Light Pro Head Features The Surefire KE2-T Turbo Scout Light Pro Head uses a virtually indestructible ultra high output LED that produces 700 lumens of light. The turbo reflector concentrates the output into a tightly focused beam for positive identification farther downrange with 70 000 candela of maximum intensity and a listed distance of 529 meters. It runs on two 123A batteries and produces tactical level light for 1.5 hours. The head works on non-Dual Fuel M600 and M640U Scout Lights including the legacy M600. The body is lightweight aerospace aluminum coated with a Mil-Spec hard anodized finish and the window is tempered for toughness. At 1.9 in length and 1.8 oz the head is built to withstand hard use without weighing down the weapon. Upgrading is simple because the head replaces the existing one on a compatible Scout Light. The result is turbo high candela performance in a compact durable package that suits users who need reach.
