For a technical user who expects all-around performance and features out of their headlamp but still values a small size and compact package. The 'dual-fuel' system gives you charging flexibility with a battery meter for monitoring its status. The IPX8 waterproof rating allows the headlamp to operate at least 1.1 metres underwater for 30 minutes - so you can beat the dead batteries out bush and brave the after-dark fishing. Beaming with a maximum lumen output of 400, enjoy a dynamic duo of dim and full power with the PowerTap technology for instant transitioning. Brightness Memory is the resulting feature of another lightbulb moment by Black Diamond - enabling your chosen brightness to remain even after switching off.
