PETZL NAO RL bk | E105AA00 - Reactive Lighting Technology - LED Flashlight - Black

This thing is great. I've tried a few other head lamps that were cheaper. But this one is superior. It's light weight, and the mass is balanced on your head. I was a little sketchy at first about the type of head band but now I'm very happy with it. It's such a light touch that I almost forget I'm wearing it. And the battery is superb, I can run the light all day and only lose 1/2 a charge. Some of the cheaper head lamps I tried had junk batteries that would lose voltage over time resulting in a dimming effect. This light stays full brightness all day long. I'm talking longer than 12 hours of continuous use. My guess it would go 24 hours but I've not tested it. UPDATE: Ok, I have tested it for two days. Keep in mind this thing has two modes, adaptive and fixed or whatever they call it. Adaptive is the default whereby the light intensity self modulates based on ambient. But sometimes you might not want it to; you can switch to fixed by holding the button down for a few seconds. All my testing so far has been in the default mode. So, I have now run it for two 14 hour days; I get up by 0400 and run the light continuously until 1800 hours, 6 PM. I have now confirmed it will run two days with battery to spare, ~1.5 bars. When I shut it off yesterday (after two 14 hour days) it showed 2 of 5 bars on the battery but when I plugged in the charger the second LED was blinking so I figure I had about 1.5 bars left. I wear it all day, with all other lights in my 3200 sq. ft. shop shut off unless I need to light up a work area. I'm seeing a noticeable decrease in my KwH electric usage. I'm estimating $80-$120 decrease per month. This thing will pay for itself in less than two months. I'm in California where I'm paying 42 cents per KwH, sometimes as high as 65 cents in the summer. YMMV.

これの前はIKO COREを使っていたが、無くしてしまい奮発して購入しましたが、こちらの商品は自動的に照度を切り替えてくれるのが本当に使い勝手が良いです。 最大照度にしていても、手元を見る際や明るいところに出ると調整してくれます。 残念なところはケーブルが剥き出しなところとバッテリーが専用ということです。 それを含めても次もまたこれにすると思います。

Très satisfait, arrivé dans les temps, lampe tres legerte, bonne autonomie de la batterie. La fonction automatique fonctionne bien. Il faut s'y habituer. Comme mentionné dans les instructions lors de sport rapide comme le vélo la fonction standard est plus securitaire. Je suis bien satisfais.

Magnifica luz para correr por la noche. Peso muy equilibrado, prácticamente no se nota en la cabeza y no se mueve en absoluto. Una hora en modo reactive ha consumido tres de las cinco puntos indicadores de carga, en el nivel tres, el más alto. Tengo otros frontales y este es el que menos atenúa la intensidad de la luz, que siendo buena, me parece algo focalizada. No obstante, los reflectores hacen su trabajo, iluminando bien a lo ancho del camino. Puede que el sensor de luz sea muy sensible, un simple reflejo en una señal o el propio vaho de la respiración hacen que la intensidad de la luz fluctúe mucho. Cosa que se evita mirando al suelo, donde la luz permanece fija. El envío de Amazon muy bien, un día antes de lo esperado.

A great quality product with excellent light
