A powerful output and a suite of useful features distinguish the LEDLENSER H19R Core LED Headlamp, designed for the most demanding of professional or recreational settings. The H19R Core is equipped with separate, independently adjustable flood and spot beams, so you can select the light you need for your immediate surroundings as well illuminating objects a considerable distance away. Peak output is 3600 lumens on the boost setting, a rare power level among headlamps, and the 7.4V battery can run the light for 15 hours at the 200-lumen low setting. The brightness levels are dimmable in order to achieve the perfect level of illumination, but you can also opt for the Optisense feature, which selects the correct output based on ambient light. A red light mode allows you to see well enough to perform tasks in the dark, without disrupting your night-acclimated vision.

The headlamp's aluminum and polycarbonate housing is IP67 waterproof and dustproof, and tested to withstand drops of 3.3' without damage. Recharging the 4800mAh Li-ion battery is as easy as snapping on the magnetic charge cable (charge time is 5 hours). An overhead strap distributes the weight of this substantial lighting tool for comfort and support.
