Things to look forward to I guess..
    One line in their firmware that tests and rejects distance adjustments of less than half a meter will solve breathing issues. But haven't they figured that out by now? I think you can access the headlamp software, right? So if that's the case, Petzl could make the change and have a firmware update for their customers available on line in a matter of no time at all.

    If you want to read a map, just go manual. I would think auto adjustments are preferred for when you're moving anyway.

    As for fog, I'd just go manual when that happens. Headlamps are pretty pointless in the fog. You want to shoot from the hip with a narrow beam or minimized spill when that happens.

    But I don't know much about this headlamp, so shoot me. I tried.

    HI

    I have the first mod of the nao and are thinking of getting the new nao+. But after reading this thread I starting to lean to ask for help to mod it with a new stronger led and maybe get away a little cheaper.

    is someone here on candlepower willing to help me mod it with a newer stronger (warmer) led?

    Sohl - it can be done, but I don't know if the shipping rates and delivery time will not kill the whole idea.

    Hi there!

    FYI - today I tried the NAO+ battery in my NAO1 headlamp. It seems to work just fine. The petzl compatibility chart states that they are not compatible but it does work. The NAO1 seems to behave normal. This is the compatibility chart in pdf format from petzl: https://www.petzl.com/sfc/servlet.sh...0000002tVlpAAE

    The battery connector on the NAO+ differs a small measure from the original NAO. The center piece around the four pins on the NAO battery is oval while on the NAO+ it is more square shaped. This makes it impossible to connect the NAO battery to the NAO+ but it works the other way around. I wonder if the NAO battery would work in the NAO+ if the connector is modified (although of course with some functional impairment). Has anyone tried that?

    Greetings

    Unhappy Re: Petzl NAO - high-tech headlamp review.

    Oh how annoying...

    The mypetzl app for the NAO+ is a disaster. There are bugs that affect the user profiles in such a way that they do not work as intended when uploaded to the lamp. For example, if you define three different levels and upload them, the lamp only have two levels. Another bug is that the levels sometimes disappear from the app main screen and you have to go back and forth to make them visible again. Be aware of that the lamp flickers a couple of times when turned off so wait a while before you look directly into it or you will be temporarily blinded.

    The app in itself is unintuitive and lacks any kind of advanced options. There is no way a user may control the individual beams as in OS by Petzl. The only option is to select one of five pre-defined profiles and pull on a slider controlling the maximum reach. There is no information on how the individual beams are set in the different profiles. That is something you will have to find out for yourself by using the lamp. You may only define a maximum of three reactive levels per profile. The whole app experience feels fit for a toy lamp. Actually, the concept of using a smartphone app to control the lamp does not make good sense for any product with a life span of more than a year or two. My own experience tells me these apps gets pulled from appstore sooner or later and there is no way you will be able to reinstall them. If Petzl decide to replace the NAO+ within a few years, do you really think that the app will still be available? You may be sitting there with an expensive lamp you no longer have any means of controlling.

    I have been really satisfied with the NAO1 I have had since 2012. Unfortunately the NAO+ does not meet my expectations. It is less advanced and riddled with bugs. Therefore I decided to return it and get the NAO3 lamp instead. It seemed perfect but is very hard to find. Alas though! The guy on Petzl support tells me that the NAO3 does not work with OS by Petzl. In fact there seem to be no way at all to customize the NAO3.

    Maybe I will look into the LED hack possibilities but SMD LEDs are notoriously hard to change.

    Regards

    I've done some modding on NAO 2 - the old leds (I don't know what that was but it was no Cree) were replaced with Samsung LH351C 5000K CRI 90+. I must say that there is no huge difference on the photos, but with naked aye it's huge if you compare those side by side. Despite the fact that modded nao have over 30% more light I would say that old one looks brighter , maybe because our eyes are more sensitive to blue than red.

    The wall is beige - left Samung 351C / right generic led



    Color comparison - top generic led / bottom samsung.


    Some measurement's from integrating sphere .

    Constant LOW



    Constant HIGH

    chasm22,

    Pretty useless of PETZL, yeah we noted this too (see image beneath) but weren't able to find a way to source any.

    Meantime have reached out to Szemhazai in the hope he might mod another NAO Battery pack so we can finally use generic Panasonic/Sanyo 3500mAh 18650's.

    Big 'UPZ' to Szemhazai way over in Poland too for his work & testing on a way around and to combat the PETZL PREDATION

    New user.. digging up an old thread - please go easy!
    I have just ordered a 3450mah replacement for my original Nao *link removed
    I am sure I'll be able to charge this once it fitted to the Nao battery housing, but it would be great to be able to charge both the old and new batteries at the same time. Is there a charger available (ideally USB or 12V car fitting) that can take one of these batteries ? The obviously dont go in standard charger due to the electronics/connector.

    I have now installed this and it seems to work great. However, the lamp goes into 'reserve mode' even when there appears to be 2 bars of power left. Is this an issue with the firmware reading the battery level of the improved cell ? Is there anything that can be done to fix this ? Makes it a little pointless upgrading the battery!

    The lamp is calculating the capacity - you can put there 4000mAh battery and still it will use 2300mah if this is the version of the battery pack that you have... That's why I've posted all information's about his headlamp - to make it more usable and user friendly.

    Yes @szemhazai - I should have done my research!! Hopefully in the way to being resolved now... Thanks!

    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 .

    Is the battery life different much from what they claim ?

    No, the battery life is well calculated + more than an hour in the safety mode.

    That was one of the main reasons why I start to mod it - the lamp:
    Petzl NAO ICR1865026 - 2600mAh - burn time 3:07

    Petzl NAO NCR18650B - 3400mAh - burn time 3:10

    WTF?? After that I've fond that it's using calculated capacity to control burn time...
