LED Lenser 880200 P5.2 140 Lumen Flashflight with K2 LED Keyring Flashlight PERFORMANCE SPECS: max 140 lumens, max distance 120M, max 4H battery life, water resistance 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. MATTE "FROZEN BLACK" TEXTURE: LED LENSER developed the new "Frozen Black" textured coating for improved grip and comfort, allowing for easier handling in harsh conditions or while wearing gloves. IMPROVED RAPID FOCUS: The upgraded Rapid Focus feature allows for seamless transition from a spot beam for viewing items in the distance to a flood light for a broader light spill in a smooth, one-handed motion. REDESIGNED SWITCH: The P Series switch has been redesigned for ease-of-use, even with gloves.
