LED Lenser - M3R Rechargeable Keychain Flashlight, Black (FFP) PERFORMANCE SPECS: max 220 lumens (min 20), max distance 120M (min 40M), max battery life 2H (min 6H), 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 you're 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 (BASIC): Smart Light Technology allows you to program your light functions to the task at hand. Three light functions (Power, Low Power, and Defense Strobe) are easily operated with full or half clicks, ensuring your focus will be on the job, not on your light. 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. In Low mode this light will run for over 6 hours and can easily be charged on the go, allowing you to be ready for anything with a light you can carry with you anywhere.
