LED Lenser Headlamp H7R.2. The LED LENSER® H7R is one of the most popular battery-pack operated headlamps. In the new LED LENSER® H7R.2, we have improved upon our tried and tested features and enhanced them with the most modern of technologies and practical features: the recalculated lens ensures wider illumination, the ergonomics have been optimized and the energy concept is now based on lithium-ion-cells.
