LED Lenser H7 All-Purpose Headlamp is a professional-grade, lightweight headlamp that can operate for over sixty straight hours on its lowest setting. This LED Lenser headlamp has a similar design to its H5 cousin, but features six times the lumens and a few more features. This flashlight incorporates the patented Advanced Focus System, which uses a unique lens and reflector combination to create a single beam with two purposes; it projects both a long-distance concentrated beam and a close range diffuse flood that's good for reading or surveying your surroundings. The LED Lenser H-7 Dimming Head Lamp has a stageless dimming function that can adjust the headlight's output from its maximum 155 lumens all the way down to a paltry 2.5 lumens, ideal for preserving night vision and looking around small spaces. LED Lenser has incorporated a swiveling head into the H7 Headlamp, allowing you to adjust the beam's angle and position with one touch. The H7 comes in two different versions: a standard model that runs on three AAA batteries, and a rechargeable model that uses three AAA NiMH batteries. For an all-purpose headlamp with variable strength lighting and comfortable design, choose the LED Lenser H 7 Swiveling Head Flashlight. 3 AAA Batteries Included.
