With brightness levels typically found on high-end search lights and features including Bluetooth remote control, the LEDLENSER H19R Signature LED Headlamp is a sophisticated lighting tool for outdoor adventures. The headlamp is equipped with separate, independently adjustable flood and spot beams, so you can select the light you need for your immediate surroundings as well illuminate objects a considerable distance away. Peak output is 4000 lumens on the boost setting, and the 7.4V battery can run the light for 20 hours at the 200-lumen low setting. The brightness levels are dimmable in order to achieve the perfect level of illumination, or you can also opt for the Optisense feature, which selects the correct output based on ambient light. There's also a red light setting that won't disrupt your night-acclimated vision the way white light can. The lamp can be programmed and operated on your smartphone via Bluetooth and the LEDLENSER Connect app.

The H19R Signature's versatility doesn't end there. It becomes a bike light when detached from the headband and used on the included MTB mount. Also included are a tripod connector, GoPro adapter, a helmet mounting kit, and an extension cord that allows the battery pack to be worn or carried elsewhere. The headlamp's aluminum/polycarbonate housing is IP68 waterproof and dustproof and tested to withstand drops of 5' without damage. Recharging the 4800mAh Li-ion battery is as easy as snapping on the magnetic charge cable (charge time is 5.5 hours). An overhead strap distributes the weight of this substantial lighting tool for comfort and support.
