The updated Petzl NAO headlamp now shines from 575 to 7 lumens with REACTIVE technology to automatically adapt light output on-the-run while also helping improve battery life. A sensor analyzes ambient light and proximity of objects in your path to adjust in real-time beam shape and brightness of 2 high output LED's. Customize settings on your computer to make NAO fit your needs for brightness and battery life. If you want, switch to constant mode for traditional headlamp function; Li-Ion battery recharges simply via standard USB.

Customer Reviews

Comments: I have had this headlamp for a little over a year now, running thru 2 winters in the early morning. I bought the extended cable to wear it on my waistband and it makes it very comfortable on the head but even without, the weight is not bad. One morning when I only had a short time to go before daylight I went back to my Petzl Tikka and was so disappointed with the output. Once you switch to the NAO, you will not go back. I love the adjustable feature for when I'm on the wooded path and how it dims as the sun comes up.

Comments: This is a very nice running headlamp. Makes running in the dark much safer with its amazing brightness. Fit is secure, no bounce and very intuitive. Works with a hat too!! A great piece of gear....essential for hitting the trails at the end of the day extending mileage and possibilities greatly! thanks Petzl

Comments: I just recently purchased this headlamp, and I'm absolutely in love with it. The big change that's been made since the original version of the NAO is the ~60% longer battery life. So I have been using this with the top strap, and it's been staying perfectly put. No movement at all, which is nice. It also doesn't feel like it's "grabbing" my head which lets me forget about the fact that I'm wearing a headlamp. It does have a bit of weight to it, but that seems to fade away after a couple of miles. Worst case scenario, you can buy a kit to relocate the battery to your hydration pack or waist. The reactive lighting seems to work great in the early AM. It even seemed to handle the fog with no problems. Anyway, overall I'm very excited about this product. :)
