LED Lenser - X14 Flashlight, Black PERFORMANCE SPECS: max 450 lumens (min 70), max distance 350M (min 140M), max battery life 1H 30M (min 10H), 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. 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. RAPIC FOCUS: With one hand and one movement, you can achieve seamless transition from close to far and all points in between. X-LENS TECHNOLOGY: An industry first, X-Lens Technology combines multiple LEDs into one seamlessly-projected beam of light. Add to that an optimized heat synching system that enables us to drive our LEDs harder and you get unprecedented output from common batteries in handheld sizes.
