Petzl NAO - high-tech headlamp review
NAO is the latest headlamp from Petzl - which brings together all the technological innovations of the past few years. Cree XP-G LED’s as a light source, 18650 Li-Ion cell as a power source, programming modes and charging via USB. Anything else? New Zephyr carrying system and "Reactive" - the system that automatically adjusts the light to your needs...
Impressions Nice, relatively light (instead of 187 catalog it weighs 190g, but it's a small difference) it appears to be a lamp refined in every detail. No edges except for switch - the switch itself is large and very easy to use. "Eye of Sauron" - as some call light sensor, for certain will attract the attention of every customer :naughty:. The new strap system works flawlessly - the only thing that you have to do is to push the lock and tighten / loosen the tie on the back of the head. Headlamp keeps itself on the head very firmly, 4 anchor points on the battery holder greatly enhances its stability during the run. The internal build itself is quite simple - of course if you are not trying to put everything apart . Head protector => heatsink => plastic box with driver and led’s => front cover. In accordance with the trend in recent years - LED's are integrated on the driver board – modding this light won’t be easy. The brain of this driver is STMicroelectronics STM8L151G2 Ultra-low-power 8-bit MCU with 4 Kbytes Flash, 16 MHz CPU, integrated EEPROM - yes dear user, you have a 16MHz processor on the forehead :ohgeez:. If you really want to spend some time on software development you can even make your own ROM. And maybe somebody will have to do so, because in the process of developing current firmware somebody killed the idea of strobe modes - no SOS or usual strobe in NAO. Power supply. Before the first use, the battery needs to be charged, you must be patient cos it might take a few hours. Here is a bad news for potential users - yes inside the battery pack is 18650 Li-Ion cell, but it is connected with the wire and plug, which prevents the usage of 18650 cells easily available on the market. Don't panic, the plug is commonly available Molex 5264-3P with 5263 pins, for less than $1 you can make yourself a spare cell. How does it light ? When you are covering the light sensor with your fingers to see how it works in the shop, it doesn't show you the efficiency of the system in practical conditions. But it Works !. In reactive mode the headlamp instantly changes the amount of light depending on where you turn your gaze. Just raise your head and look in the crown of the tree and the beam of light will follow . The usage of two LEDs with different collimator angles allows you to see what you have just under your feet as well as objects that are far away. My NAO have a pretty nice tint of light, but the manufacturer does not claim to use selected LED’s, so as usual it may depend on the series. Petzl Nao - HIGH - about 300 lumens. Petzl Nao - reactive mode - HIGH. Black Diamod ICON 2012 - HIGH - about 200 lumens Princeton Tec Apex 200 – HIGH Summary. Ideal headlamp, almost – the power supply was unnecessarily complicated, they can follow the Sparks idea to use standard 18650 cells and combine it with reverse polarity protection to make it fool-proof. Then with 2 spare cells in your pocket user will have enough energy for whole weekend or even longer. But they choose the “Petzl’s way”, so now the user have to pay or make it by himself. The Reactive Lightning system works fine, despite my initial concerns - although we will have to wait a bit to see how it will react in a dense fog, or when stuck in snow. In the manual there is a warning to do not use the headlamp in reactive mode during road biking – the lamp can switch off itself when encountering a car with headlamps on. So there are some risks . Is it worth it ? In my opinion yes, but for sure it is quite expensive headlamp and not for every pocket. I still think that if they will cut reactive system, overcomplicated power supply, and make the NAO into almost normal headlamp powered from 1 or 2 18650 for $100, the competition would not have any chances. Definitely there is a room for RXP 3 on the market - but so far the Petzl NAO will be a class for itself . PS.

Re: Petzl NAO - high-tech headlamp review
Неужели пецл одумался, и родил хотя бы пародию на что то современное?
Зы, теплоотвод какой то слабенький для такого потока, и питание какое то странное, я бы не купил из-за корявого 18650 на борту и внешнего провода, ибо слабое место.
