The Led Lenser iH6R is battery-operated. The headlamp has a luminous flux of up to 200 lumen and a beam distance of up to 120 meters. It ergonomically adapts to the shape of the head. The headband is washable and has a rubberized inside which prevents slipping. Of course, the iH6R can always be adjusted to meet the requirements of the relevant workplace lighting needs, thanks to the light, dim, and focus functions.
