Ledlenser HF4R Core headlamp is a slim, lightweight, and waterproof base model for everyday use when you need a basic headlamp for camping or taking your dog for a walk. It has two separate light sources for close and far-range illumination as well as a separate red light to preserve your night vision. The stepless tilting lamp head and the integrated battery provide maximum flexibility. When reading in your tent, you can tilt the light to where you need it the most without an annoying battery box at the back of your head. You can easily charge the integrated battery via the Magnetic Charge System – even during operation.
