LED Lenser H5 AFS Jogging Headlamp 880038 is a comfortable, exceedingly bright headlamp with a few extra features that push it to the top of the headlamp pack. This powerful head lamp uses the patented Advanced Focus System (AFS) popularized on several LED Lenser flashlights. The Advanced Focus System uses a reflector and lens combination to create a dual beam, giving you one exceedingly bright focused beam for long distances and another, more diffuse area light for reading and close-range tasks. The only headlight on the market with the AFS system, the LED Lenser H5 Dual Beam Head Lamp is one of the more versatile headlamps you can buy. The headband is soft with this LED Lenser headlamp, and the flash light's light weight make it easy to carry during extended periods. LED Lenser has even included a red backlight on the headlamp, excellent for nighttime bikers and joggers who need a little extra safety. With a 25 lumen output and a 21 hour run time, these multiple-use headlamps can give you sterling illumination for almost a full day on nothing more than three AAA batteries. For a reliable headlamp with two beams, a red safety light, and comfortable design, choose the LED Lenser H-5 25 Lumen Head Flashlight.
