The Core headlamps are the foundation of the H-series. They can be operated intuitively and offer stepless dimming via the Wheel Switch on the lamp head (except H19R Core). In addition, the headlamps provide an improved constant luminous flux so that the selected brightness can be maintained over a long period of time. Thanks to the Flex Sealing Technology, all models achieve extreme dust and water protection (at least IP67). These and many other features as well as the extensive range of accessories that can be used universally with the Ledlenser Connecting System, make the Core headlamps of the H-series ideal all-rounders for a variety of uses and activities.
