Klarus HL1 Headlamp Extraordinarily Lightweight The new Klarus HL1 Headlamp was designed to be used in multiple environments and by a wide range of users. The HL1 is extremely lightweight and balanced with its two-strap headband design - ideal for rigorous activities and sports. The headband is constructed from a breathable material and is adjustable in two areas for a perfect fit. Using this headlamp for caving, climbing or utility work? No problem - this package includes four helmet clips to quickly and easily attach the HL1 over a helmet or hard hat. Dual Lighting The HL1 is equipped with dual LEDs to ensure users have every lighting mode available - ranging from moonlight, to red, to signal modes. The main light accesses moonlight through high brightness levels, while the auxiliary light offers red lighting and signal modes. The auxiliary light also doubles as a battery indicator for remaining battery power and to show charging process. Never have to buy two different devices to illuminate the next adventure again - the HL1 has it all. Detachable, Rechargeable For close range or personal lighting, the HL1 can be easily removed from the headband and bracket for EDC and desk use. Place the lamp on it's end for a solid tailstand for tent illumination or night-time reading. The built-in micro-USB charge port charges the included 18650 li-ion battery within 3 hours.
