LED Lenser's CORE head torches are the foundation of the H-series. They can be operated intuitively and offer stepless dimming via the wheel switch on the torch head. In addition, the LEDs 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. These and many other features as well as the extensive range of accessories that can be used universally with the LED Lenser Connecting System, make these models ideal all-rounders for a variety of uses and activities. The H7R CORE fits securely onto the head and can deliver a powerful 1000 lumen beam when required. Additionally its watertight construction makes it a robust and reliable choice which is ideal for active outdoor environments. It has a rechargeable battery which is charged via a magnetic cable. The battery can run for up to 65 hours in low power mode and can be fully recharged in under 4 hours.
