Headlamp LEDLENSER H21R - 10000 lm / Rechargeable

The Ledlenser H21R is a rechargeable headlamp with a maximum light output of 10,000 lumens, designed for demanding users. In addition to its powerful performance, the lamp also incorporates today's cutting-edge technology, such as the Adaptive Light Beam, which allows for complete "hands-free" use, which automatically adjusts both the light output and the light beam to suit the environment, leaving both hands free for work or hobbies. Of course, the functions of the lamp can also be adjusted manually, allowing the user to customize the light settings to their own preferences. In addition to white light, the lamp also has RGB lights (red / green / blue), which can be used for, for example, observing forest animals, tracking, fishing, maintaining night vision or reducing glare for others.

The light output of the lamp can be adjusted continuously between 40 and 3500 lumens, and the lamp also has a Boost mode designed for situations requiring maximum lighting, which temporarily increases the light output to a whopping 10000 lumens. The range of the light beam varies between 40 and 400 meters depending on the narrowness of the beam, meaning that the same lamp can be used for both broad illumination of the immediate environment and precise spot lighting of more distant objects. If necessary, the lamp can also be controlled remotely via the convenient Ledlenser Connect mobile application. The application also offers various customization options for the lamp's functions.

The battery is located at the back of the headband, where it acts as a counterpart to the light head, ensuring even weight distribution. The red light integrated into the battery housing acts as a handy rear light, increasing the user's safety and visibility in traffic. The headband, made of soft and flexible material, does not cause a squeezing feeling even during long periods of use, and the upper support band provides stability for faster riding. The lamp comes with a handy Velcro fastener and mounting clips that allow it to be attached to, for example, a work helmet. Two-year (24-month) warranty!
