At the end there will be a summary for those who like only particulars. In each topic I will bold the key sentences, so it will be easier to notice what's the most important. Enjoy!

note from the translator - isn't it the most uwu package you've ever seen??
I've picked the orange version, because it's my favourite colour
The headband is also orange - there is one strap around the head, cause the top one is redundant. The headband is wide, it will fit on every head and Armytek should take an inspiration from Wuben and finally understand that there are also people with bigger heads or people who would like to wear a headlamp on their winter hat.
We can rotate the flashlight up and down just like a standard headlamp, but the handle also allows 360° rotation in a plane perpendicular to the standard plane. I hope the picture will help to understand it
This gives you a lot of hooking and positioning options.
In the front, there is a plastic lens and behind it we have an Osram P8 diode, on the side there are 2 diodes of red and blue light
On the left side (while having it on) there are 2 buttons, a separate switch for white light and colored light - what a good feature!
On the other side is a battery cover with a rubber O-ring. It's very hard to open, because the catch holds tight and it takes a lot of force to bend it back. The disadvantage and advantage of the presence of the o-ring, well. Or maybe it is because the headlamp is probably also directed to small users, and it would not be advisable for them to open the battery cover. It may happen that they'll like it and.. that would not be good...
It is powered by 2 AAA batteries, which are the small ones. Generally available in every mountain kiosk, so on the trail you do not have to worry about lack of light. Used cells, to save weight, can be thrown away on the way to the container for used batteries.
UI
3 looped modes: 1lm - 50lm - 120lm. On/off by click, hold to change modes. Same with the second button for red and blue light. When the flashlight is off, a double click on the white light switch activates SOS. So you have to be careful, because you can accidentally( by turning on the flashlight) attract people who want to help you.
Runtime
I tested the runtime of the medium mode, which is about 50 lumens on two sets of batteries:
cheap, about 1$ for 4 pieces
and twice more expensive, $2 for a pack of 4.
The result? Did twice more expensive turn out to be two times better?
No, Nein, Нет, Non, Nie...etc
The difference was small, about 15 minutes more on the better ones. Both sets did not last the claimed 7 hours, the most was 4 hours and 44 minutes until the brightness dropped to 2 lumens. I did not do longer tests, because it was supposed to be 7 hours on medium mode, not 7 hours until it goes out.
The pros are definitely the brightness stabilization, which is positively surprising.
Charging
There is no charging, as you will power the flashlight with two AAA batteries. You can of course use AAA rechargeable batteries and charge in your charger.
AAA is definitely an option for followers of constantly buying batteries in the mountains.
I observed small (meaning fast) PWM on low mode
Declared IP65, so full resistance to dust, but it is not full resistance to extreme rain or immersion. Certainly it is enough for basic use, i.e. in such conditions in which 90% of people use headlamps
Osram P8 LED with a cool white tint and a maximum brightness of 120 lumens. The light is pleasantly diffused thanks to the reflector with non-uniform texture.
There is also a red light (steady and flashing) and a blue light
Both light up at low power and are suitable for use at close distances, about a meter.
ISO200, t2s, f/3.5 sunlight white balance
It is sure, that we will not see a blinding light here, the camera settings are adjusted to well reflect the light of 10 000 lumens, so it is logical that these dark lights are performed rather poorly. 50 lumens is enough light for walking in the dark, and a headlamp as 120 lumens will also work for some time.
The red light was too dark, very little can be seen in the picture, it is also rather weak as a light for comfortable walking
And here are pictures of shining under your feet
At first I was skeptical about this flashlight because it's plastic and has some boy on the package. A lot changed when I saw the price, because it costs 16.99$ per one, and on the Wuben website when buying 2 at once it's 5$ cheaper, which is just over 14$ for one. The option for 2 people is very cool, especially since both headlamps come in different colors. I especially like the clip that can be attached to the backpack, or on a cap. On the backpack you can set the flashing red light when walking by the road.
It's a pity that the lens is plastic, and thus prone to scratches. If it weren't for this detail, there really wouldn't be much to complain about. At the price of 17$?
Wuben H3 is a small and light headlamp. In order to reduce weight, it is made of plastic and the headband does not have a top strap, which is unnecessary at this weight. Powered by two AAA batteries, it produces white light with a maximum brightness of 120 lumens, as well as red and blue lights. IP65 doesn't assure that no water will get inside, but supporters of travel in bearable weather won't complain. All you need to do is to attach it to a headband, or, as a standard, to the visor of your cap, or to the strap of your backpack - at the front to shine a white light, or at the back to activate the flashing red mode and mark your position while walking e.g. by the roadside.
For the price of 29$ you can get 2 pieces, in addition they are in different colors in the set. I sincerely recommend as an emergency kit for 2 people, to take for example to the trip in the mountains. It is difficult to find something for 14.5$ per one with such parameters.
PS. I really think so.
Pros:
+ Small price
+ Lots of installation options
+ Red and blue light
Cons:
- Plastic lens
- Very heavy battery cover opening
- Runtime lower than declared
