Brilliant performance under extreme conditions: The H21R is designed for extreme sports on land and water, as well as demanding work environments underground and at night. The powerful headlamp provides reliable illumination—and reveals obstacles when riding downhill on a mountain bike in the dark, guides your way on the boat in poor visibility or effortlessly illuminates vast tunnels and railway tracks. In spot mode, it can be used as a powerful signal on the water or in the air, while its homogeneous flood light allows you to discover the smallest details up close, such as a barnacle on the anchor of your boat or a minor technical malfunction affecting the engine of a train. To make sure you always have the best possible light, you can rely on the innovative Adaptive Light Beam for automatic dimming and focusing and thus hands-free use of your H21R. If you prefer manual control, the enhanced Digital Advanced Focus System is the way to go. Use the buttons to digitally switch from flood to spot to suit any range or task. You can also choose between red light to help you preserve your night vision, green light for wildlife observation and blue light to make liquids visible—while the optional red rear light and reflective headband offer additional visibility. The powerful battery also operates while charging, so you never run out of light on your adventures or a long shift—and is located at the back of your head for a balanced weight distribution. You can also easily mount the H21R on your helmet via the included mounting accessories and use the Ledlenser Connect App for remote control and personalization. When not in use, you can safely store and transport your headlamp in the exclusive hard-shell case. And: Our lights are made for a brighter future—therefore, your H21R contains recycled materials21.

If no setting is specifically named, the luminous flux (lumens/lm) and range (meters/m) values refer to the brightest setting and the burn time (hours/h) values refer to the lowest setting. A boost function (if available) can be used several times, but is only available for a short time at a time. In case the lamp is equipped with colored LED(s), the measured values are given with white light or the white LED. If the lamp has different energy modes, the "energy saving mode" is the basis for the measurement.
