With optimized power management technology, it incorporates German focal design technology for a super bright, super tight beam and a CNC-machined aluminum head that will perform in all weather conditions. This headlamp is easy to operate and has a rotary control knob with four brightness settings and a strobe feature. Battery pack features an ultra-powerful 12V nominal Li-ION power source, a push-button battery charge indicator light that easily displays battery life at any point during use, and at battery critical levels the headlamp will send a periodic warning strobe instead of blacking out during use.
