Review: Fantastic Headlamp!!! - Holy cow - this thing is bright!!! On its brightest setting, it sure turns night into day. Even the low setting gives plenty of light if you're walking a trail or performing a task with others where blinding them is frowned upon. The adaptive technology seemed to work as advertised; there was just a small brief delay when auto transitioning up and down. I use mine for search and rescue and really need more light over weight concerns. I bought an extra battery and keep a USB charging device in my backpack - thus I tend to leave the light turned up high when maneuvering through thick stuff. The battery surprised me and lasted longer than anticipated. Even without reading the instructions, it was pretty intuitive changing the brightness and turning on/off the adaptive feature. Fit on every helmet we tried. Pricey, but well worth the money if you need a good, rugged dependable light source in rough terrain. Review: The BEST headlight, but with two BIG flaws: no strobe, buggy software - I bought one of these for work, then I bought another one to use while running, then a friend was impressed with it so I bought one for him... I've bought 3 (so far) so they must be pretty good. This us a really nice, bright, light. It is lightweight and comfortable. The battery recharges with an iphone charger. Most impressive is the brighness. It is not as bright as a car headlight, but the beam is more focused so it appears more noticable and dazzling to car drivers. I have a bunch of nike 'flash' jackets which are very reflective but car drivers still come dangerously close. I have tried a couple lesser headlights from streamlight, energizer, etc, and they make no difference. With this light, the majority of cars can see me and move over. Some drivers flash their full beams back, as confirmation that they see and acknowledge me. However, I really wish there was a strobe feature to make the light even more attention-getting. I have had a couple close calls even with this light, and with this light you can see inside cars and see the drivers staring at their phones. A strobe feature would help get the attention of distracted drivers. The computer software used to customize the different modes has a lot of nice functionality, but it's a joke to use. It doesn't work at all on mac osx if you have a retina screen. Half of the stuff just can't be clicked on. I set my headlight up in windows running vmware fusion, but I later found out it will work if you have an old, non-retina screen. It worked at my shop when the computer was connected to my thunderbolt screen. At this price level, even as good as the light itself is, to have no strobe or flash feature, and buggy software is kind of inexcusable. It would be really neat if you could program in different strobe patterns. Pretty please, Petzl? I'll buy more if you update them! As it is, it is still as visible on full beam even without flashing as other lights are in disco-mode. Also, the reactive lighting feature works very well, I use it a lot on the trail and at work, but it's pretty much unusable in traffic (as you might expect) ## Features - Compact, powerful and rechargeable headlamp with REACTIVE LIGHTING technology for technical, dynamic activities - Headlamp is stable on the head: adjustable headband with top strap for technical activities - CONSTANT LIGHTING mode is also available, guaranteeing stable lighting that does not diminish during the entire chosen burn time - Optional belt kit for NAO allows the rechargeable battery to be moved to the belt to reduce the weight worn on the head, or to keep it warm in winter ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00LMCATH4 | | Additional Features | Headlamp comes with rechargeable Lithium-Ion battery and 30 cm USB cable | | Batteries are Included | Yes | | Battery Description | AAA | | Battery Type | Lithium Ion | | Best Sellers Rank | #3,254,399 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #5,504 in Camping Headlamps #16,708 in Flashlights (Tools & Home Improvement) | | Brand Name | PETZL | | Color | Gray | | Customer Reviews | 4.2 out of 5 stars 435 Reviews | | Global Trade Identification Number | 03342540099593 | | Included Components | Battery, Head Band, Usb Cable | | Item Type Name | Headlamp | | Item Weight | 0.19 Kilograms | | Light Output Maximum | 575 Lumens | | Light Source Type | LED | | Manufacturer | Petzl | | Manufacturer Part Number | E36AHR | | Model Number | E36AHR | | Number of Batteries | 2 AAA batteries required.

There is the model E36A which has been discontinued, but some dealers may still have in stock. I think it had 350 lumens. Petzl released a new model last month, model number E36AHR. It has 575 lumens and a larger capacity battery. **Q: Is this Nao ( old model) or Nao 2 ? In search results it shows as NAO 2. The title says Nao.** A: HelloThe Amazon Number is B00LV16UHO for the NAO 2 575 lumens.Just search this number in the Amazon search box. It will make sure you get the NAO 2.B00LV16UHOThe new NAO 2 battery (more capacity)Just search this number in the Amazon search box. It will make sure you get the new battery.B00MNURF8U **Q: How many lumens?** A: From the petzl website: Max 355 lumens (reactive mode), 315 lumens (constant brightness mode). In reality, you will use the lamp in reactive (variable) mode. Operating range for this mode is 98lm-355lm. http://www.petzl.com/us/outdoor/headlamps/nao/nao-headlamp/performances **Q: Is this headlamp water resistant? I didn't see that in the description info.** A: I haven't swam across rivers with it, but while wearing it I am drenched with sweat and I have run through some pretty torrential down pours; so I would say yes, it is water resistant. The battery connector is a sealed connection indicating it can sustain water. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic Headlamp!!! *by G***S on December 8, 2015* Holy cow - this thing is bright!!!

This is a product that is both an exception to my "no review" policy and exceptional in execution. This one does it all. It is a smart headlamp that is equally at home on your head or helmet. It senses what you are doing and adjusts the light to meet the demand. If you are on a trail after dark, the long distance beam is on. Stop to check the map & GPS and the lamp dims to the level needed for that close-up work. Petzl has created "reactive lighting" and has done it very well, indeed. The headlamp has a rechargeable battery (N.B. it comes with the battery disconnected - you have to open the battery case and plug in the battery before you charge it for the first time). The battery charges from the ubiquitous USB connector (a male connector is part of the battery case). Your battery life can be very short - less than 2 hrs - if your use requires constant highest light output (way brighter than any other headlamp I've ever used, including a Carbide Lamp!), or it may exceed 50 hours of continuous use in the average camping/hiking situation. A slick feature is the ability to replace the rechargeable battery with two AAA cells (at a loss of some brightness and automatic functions) if your rechargeable battery is discharged. Given the ubiquitious USB adaptor for automobiles and backpacking solar panels, switching to standard AAA cells won't be a common choice - but it is nice to have an alternative when necessary! It gets even better! Petzl has created a program to tweak the headlamp! A free download for Mac & Windows machines, the Petzl application allows you to name your headlamp and the battery, as well as to store up to four (4) "profiles" for your headlamp. The standard is Petzl's "Multi-activites" profile. You can choose to include three other profiles (including ones that you create!). Petzl provides the standard as well as: "around-the-house", "bivouac", "Mountaineering", "Orienteering Race", "Trekking / Hiking", and "Caving/Spelunking". The only activity I don't believe this headlamp is appropriate for is open-water / white-water rafting & kayaking. It is not "submerged" waterproof though it handled a brief afternoon mountain downpour without harm. It's fairly pricey until you factor in the cost of disposable batteries. If you use your headlamp often and frequently have to adjust the light level (as I always do when tying on a new fly) your battery costs will offset the price in six months, or less.
