Great condition used Petzl Nao headlamp with spare battery.
A few years old (purchased when they were just released), but only used a handful of times for adventure racing, so little wear and tear, and only maybe 40 hours of use on the bulbs and batteries!
Great headlamp with reactive or constant light. Reactive lighting tech causes the headlamp to automatically adjust the brightness based on where your looking. Lower light is used when looking down, and higher volume of light for looking father ahead. This gives a massive increase in the burn time, and still allows for quick adjustments to the light volume automatically.
Maz output is 575 lumens with the 2600 mAh Lithium-Ion battery with an integrated USB port for convenient charging.
