The Chinese have mastered the production of all kinds of flashlights. Powered by batteries and rechargeable batteries. I had a headlamp with a bunch of weak lights. And powered by 3 AAA batteries. I gave this flashlight to my son, because he lost his same one at work. By the way, these were donated lanterns ...
I decided to choose myself convenient for work and economical. Chose on Aliexpress

With 1 button press, 2 LEDs light up, with a second press - 4 LEDs, with 3 - 8 LEDs
Powered by 3 AAA batteries. So, from the beginning there was an idea to power from 1 baht. AA. It is clear - you need an economical converter ...

I use this one.

Moreover, he took it cheaper ... Excellent charge. I bought one after the experience of using it and took away the usual AA batteries from my wife and daughter. And sometimes they sometimes ordinary batteries managed to stick there, or confuse the polarity ...)))) And in this - it’s not scary!
I have a headlamp here.

No one forces him to focus - he has a very wide angle. But the amount of light is huge ... In your opinion, is it more beneficial for the eyes to squint to examine small details in the twilight? ))))

As you can see, everything is cheap. And it works great. I buy on Ali since its opening. And before that he used TiniDil, Dino-Direct, Tmart and others.

Ali-Express is particularly good at “customer protection” - there you will completely return the money if you get a marriage. On several occasions, something came up with a miserable malfunction, I opened a dispute, returned the money, or waited for re-sending, and then just fixed the malfunction ...

Looked, for specifics - charging Fenix ​​ARE-C2 (for Li 18650) = 4.390rub ($ 66)
And on AliExpress I took a cheaper block, they sent a frank marriage that was not working ...
The forehead IMHO needs the most powerful. (I have L2). Because it is used mainly when repairing something in the dark.
Just the opposite. Need diffused light ... There are hygiene standards for different jobs. When the darkness is continuous, bright directional light cannot be. There will be fatigue and headaches, etc.

18650 first took on Ali. The original can be found in 3, if you take 10 pieces .. Then, in general, I picked up the batteries from the laptops as dead and from each you can select several cans of the living .. Charger - Nitecore was taken there for 20 with something, and not for 200. There is for 2, but they can ditch. There are 15 branded ones, but without a display, you won’t check the batteries.
The forehead IMHO needs the most powerful. (I have L2). Because it is used mainly when repairing something in the dark. To free your hands. And during the repair, you just need to fill everything with brighter light.
And in other cases I don’t use it - it’s not convenient when something hangs on my head, firstly, secondly, it’s more convenient to direct the beam with your hand where you need to. Therefore, I have several T-6s for this.
In general, I’m a rather scattered person, because at the same time 40 things are spinning in my head. Therefore, knowing that I would forget to take a flashlight, I bought several of them and put them one in a car, one in the basement, one at home, etc.
On the keys hangs a "keychain" with Q-5.and 16340. This is "to the extreme")))). But even it can illuminate well 20 meters. Agree, indicator diodes are not capable of this ...
In any case, a powerful flashlight that can burn for several hours is always better than a weak one, which for a long time is not enough ...

And since 16340 and 18650 appeared

I don’t have 18650 for $ 6 and accordingly a very “cool” charge for $ 200
The priorities are slightly different. : biggrin:
For a headlamp (light, economical, "long-playing") flashlight does not need a headlamp T-6 or L-2. Although doing with sticking out at 5cm LENS. This is so cool and lumens in the eyes ...
But, AA batteries run down to 1.3V, which are thrown out by users of the camera, there is. By the way, before there was a requirement for the use of batteries in children's and TP toys. The performance of the toy (gadget, according to the present) should have been with a discharge of up to 1V and below (for a 1.5V battery, respectively)

- what's the point?
Do not reduce the volume, you will lose efficiency, reduce the operating time.

There is probably not much sense ... Moreover, the box somehow needs to be redone under an extended battery and scarf. And the operating time can be compared. There are no numbers ...
But, for example, the work on replacing the “Krona” battery (about 6 years ago) with a 1.5-volt battery (according to an article in the Radio Station) was unfinished. Now we have to finish it.

I completely agree ... I, on the contrary, redid the flashlights on the 18650. Not forehead, but simple. I bought extension rings in China, threw out the "cassette", put the battery in ... Only now, and it is not needed ...

Three such pieces are lying around ... I don’t know who to give - nobody needs anyone ... And a few more ordinary, not forehead ...
Since the flashlights appeared on the T-6, L-2, I don’t want to use these “multi-LED” ones ... I even have a flashlight-keychain on keys on the Q-7 ....
And since 16340 and 18650 appeared, I don’t want to bother with batteries somehow ...
Sorry, I live far away ... I would give ...))))
