Overview
This was the only headlamp to score perfect 10's for both trail finding and close proximity. The beam quality and power are all you can ask for in a light. That said, three things kept it from getting an award: it has abysmal battery life, the re-active lighting can be frustrating, and it is 3-5 times the cost of many lights that scored higher and are much lighter. If you love Reactive lighting, we would likely go with the Petzl Tikka RXP which is much less expensive, lighter and has a much longer battery life.

Performance Comparison

Trail Finding
This headlamp has a near perfect trail finding beam and scored a 10 of 10. The light is even over distance and powerful. In the beam comparison photo with the Coast HL7 below, you can see the difference between a beam that just goes far (Coast), and a beam that evenly and fully lights over the same distance (NAO).

Close Proximity
Another 10 score here. Below the NAO casts an even beam across the target where another 10-scorer for trail finding, the Fenix HP11 concentrates too much light in the middle.

Battery Life
The NAO was one of the only headlamps to score a 1 for battery life. In high beam mode, as shown in this battery life vs. beam distance graph, the NAO beam power falls off a cliff after an hour and is gone after 2. The Coast HL7, which only scores a 3 for battery life, is still dramatically better than the NAO. One hour of high beam, for such an expensive and heavy headlamp, is a bit hard to swallow. Yes it's cool that you can charge the NAO from any USB source, but if you only get a few hours of use between chargers, that power source better be handy!

By comparison, the newly released Petzl Tikka RXP lasted 5.2 hours in our test for ANSI measured high beam test (to learn more about ANSI, check out our Headlamp Review). This battery life vs. beam distance graph shows just how much better the RXP does over the NAO.

Brightness
With a measured max beam distance of 103 meters, the NAO is powerful but not particularly noteworthy. The Coast, costing over $100 less shined 128 meters.

Weight
At 190 grams (6.7 ounces) this is one of the heavier headlamps. The unique headband carries the weight well, but we still feel this headlamp is more weight than most people want to run with, especially considering good trail finders like the Black Diamond Spot that are less than half the weight.

Ease of Use
The Reactive technology is very cool in theory and not other manufacturer in our tests offered it. Turn on this mode, and the light chooses the best brightness for your needs: high beam for trail finding and low beam for close proximity and battery saving. In practice, this technology can be as annoying as it is useful. For starters, this and the Petxl Tikka RXP (which also uses Reactive lighting) are some of the few headlamps we felt we needed the manual for to operate. Once through the learning curve, the Reactive technology was frustrating around camp. As you mill around people, the kitchen and campfire, the lighting mode is constantly changing and not always where you want it to be.

Best Applications
This is hard to recommend for trail running because it is so heavy. So many lights with almost as bright a beam are half the weight. With the short battery life, this is really for short excursions near and usb charging port.

Value
This $175 light is one of the most expensive tested. You can almost buy one of every award winner for just a little bit more. This would be OK if the Reactive lighting was a game changer and there was some decent battery life, but this is not so.

Conclusion
This is one of the most innovative headlamps ever designed. Everything about it is cool from the look, the headband, the built in USB plug and the Reactive lighting. Unfortunately, its hard to recommend this headlamp because the battery life is so short and it is dramatically more expensive than many headlamps that scored higher. The Coast HL7 is much easier to use, lighter, has a longer beam distance and is a 5th the price. For just slightly less beam performance, the Black Diamond Icon has a bright beam that lasts about 10 times longer for half the cost. If you do love the Reactive Technology, check out the Petzl Tikka RXP which is half the cost and weight but has triple the high beam battery life.

I got the Nao as a gift after using the BD Icon for a few years. After getting used to the functions, I absolutely love this lamp! The reactive technology works very well and definitely extends the battery life dramatically. It's awesome to be walking on a low setting, then look up and see everything. Its very easy to switch to constant output lighting if you want to and its easy to program all the settings so that it will perform however you need it to. The capacity to use AAA's in a pinch is huge and still yields a bright usable headlamp (idk how well the battery life is with AAA's however).
On that note, this light is bright! I've been downhill mountain biking with it and was very pleased with the output, this thing blows the old Icon away.

There are a couple things that could be better, but in my mind they are minute.
  1. It can be difficult to fit the lamp onto a helmet when you are wearing gloves.
  1. They could have made a smaller USB port.

If you can get over those two things, this lamp will blow you away.

Bottom Line: Yes, I would recommend this product to a friend.

Since my MYO XP broke down I thought let’s give Petzl’s NAO a try. So far I think it is not that great. Yes a lot of light, best use for running at night? Quite heavy though. So far the battery life is enough for one long night out, so that is positive. To attach it on your helmet in the dark is quite something. Mind it is still warm here, but later in winter with gloves I fear that the thing may catapult down the hill in the dark. A single belt system is easier to handle. I am also not so sure if the dimmer will work in heavy snowfall. So I am back to a Tikka XP 2 to be safe at least for winter climbing.

Het had zo'n mooi concept kunnen zijn, een hoofdlampje dat automatisch zijn lichtsterke regelt.
Maar de Petzl nao hangt van bugs aan elkaar.
Hoe je de lamp nu instelt, de lamp komt nooit boven de 30% lichtsterkte tenzij je de automaat uitschakeld of de lichtcel met je vinger afdekt.
Verder heeft het apparaat een flink aantal andere bugs zoals het aan en uitschakelen, het enorme stroomverbruik en de beetje knullige accu constructie.
Ik heb hier over contact gehad met petz, maar die komen niet verder dan het terug mailen van de franstalige gebruiksaanwijzing want de software schijnt perfect te zijn.
Mijn advies, koop niet de nao maar een van zijn goedkopere broertjes.
