LED Lenser - T7M Flashlight, Black with Intelligent Clip PERFORMANCE SPECS: max lumens 400 (min 40), max distance 240M (min 100M), max battery life 1H (min 35H), water resistance rating IPX4. ADVANCED FOCUS SYSTEM: The Advanced Focus System (AFS) is the patented combination of a reflector AND lens to create a light system that provides both a focused beam for long-distance and a homogenous spill-beam for up-close reading. AFS means whether youre reading a map up close or focusing down the path to a landmark in the distance, your light will be easy on the eyes, clear and bright. RAPID FOCUS: With our Rapid Focus system you can go from reading to searching by using the thumb on your holding hand to simply slide the bezel away from you. With one hand and one movement, you can achieve seamless transition from close to far and all points in between. SMART LIGHT TECHNOLOGY (ADVANCED): Advanced Smart Light Technology offers two energy modes: Energy Saving mode optimizes burning life, and Constant Current mode features electronically controlled, continuous light output. Smart Light Technology puts you in control and allows you to choose how much power you want to use to operate your light. FOCUS LOCK: The Focus Lock system keeps the bezel from moving when holstering and unholstering throughout the day, a must for uniformed professionals.
