No matter the time of night, you can see where you are with the BioLite HeadLamp 800 Pro. Designed for professional activities, it has pro-level features and a compact design. With Constant Mode and Run Forever settings, it ensures you remain in complete control of your lumens. So you can set a steady level of brightness that won’t dim unless you tell it to. And, as a rechargeable headlamp, it can extend its runtimes indefinitely thanks to Pass Thru+ charging. This means you can use your headlamp while simultaneously powering it up. Furthermore, 8 different lighting modes enable you to see and be seen on every adventure. Finally, it has a maximum output of 800 lumens, a front panel that tilts downward with ease, and a 3,000 mAh li-ion battery that recharges via micro USB.
