Updated for 2014 to provide even more light (up to 575 lumens!), the Petzl Nao headlamp features REACTIVE Lighting technology to automatically and instantly adjust the brightness to your environment. The updated Nao also offers longer burn time, along with greater usability and fewer manual interventions.
The rechargeable NAO headlamp uses REACTIVE lighting technology to adjust its two high power LEDs instantly and automatically to lighting needs
REACTIVE technology increases battery life by making optimal use of the power source; it also preserves your vision comfort and allows the lamp to instantly and automatically access maximum brightness (575 lumens) when needed
Light sensor mounted above the LEDs monitors ambient light levels, and a processor analyzes lighting needs and constantly adjusts the two LED beams to provide seamless transitions to various lighting levels
Constant lighting mode can easily accessed at any time and offers regulated lighting up to 430 lumens
The two high powered LEDs adjust lighting from a wide close range beam to a focused distance beam, or a combination of the two if needed, with no manual switching needed
Optional OS by Petzl software (free download at www.petzl.com/OS) lets you customize light settings
Lithium ion battery provides constant output regulated lighting, performs well at low temperatures, includes a battery charge indicator, and recharges in just 5 hours via USB connection
Compatible with 2 AAA/LR03 batteries (reduces performance; not included)
Switch lock function prevents accidental turning on during transport or storage
ZEPHYR headband is adjustable and keeps the headlamp stable; includes optional top strap
Optional belt kit for NAO (not included) allows the rechargeable battery to be moved to the belt to reduce the weight worn on the head, or to keep it warmer in winter
