Runtime \ Beamshots \ Review Nitecore MH25S (21700, Type-C, SST-40, 1800lums)

Nitecore has a sort of “jack-of-all-trades” model line – MH line. These flashlights are quite versatile: you can play tactics as well as highlight potatoes stored in cellar, and somehow punch into the distance. Quite good, in general, the line, which I recalled last time in the review of Nitecore MH12. Today I will tell you about the latest representatives of this series, Nitecore MH25S.
It is worth noting that the very 1st MH25 was released almost 10 years ago and boasted an impressive 860 lumens of brightness then … almost a thousand less than the newest model.

PACKAGE AND APPEARANCE

Good package, which is no surprise at the price. Everything is good here both in design and in printing.

Kit includees flashlight, 5000mah 21700 battery, clip, type-C charging cable, holster, manual, lanyard and o-rings. There is absolutely everything you need

The flashlight has the usual size of a compact tactical model. Not EDC, but fits in a jacket pocket just fine.

Despite the simplicity of the design, the flashlight looks attractive. Take a look at the Sofirn C8G, which stands next to the battery. Also a simple design, but definitely looks cheaper. The MH25S looks neat and pleasant, although that is not sort of “WOW!“design that.

The tail-button is fully accessible from all sides. Direct click button.

There are good double springs at both sides.

A huge advantage of this flashlight is that it uses regular 21700 batteries. Accordingly, there is also an 18650-21700 adapter. For the “i” series Nitecore adds 2*CR123 adapter , motivating to buy incredibly expensive proprietary 21700 batteries.

It is worth mention that battery is maximum capacity, Nitecore didnt save on buyers and gave best capacity you may get.

Knurling is simple, in the general style of modern Nitecore models. As I said, a nice design emerges from a set of simple elements.

The clip is double-sided and can be removed with reasonable effort.

Since the tail is slightly wider than the main body, the grip is quite reliable even without the clip. In general, grip is firm and convenient.

Nitecore MH25S, albeit universal, but still a tactical flashlight. Accordingly, its head is larger than that of some EDC model, but less than some compact 21700 powered long-range models. Well, the same popular Sofirn C8G.


There are bunch of deep cooling ribs, which is undoubtly good.

I like that though button is small, access is convenient. It is just as easy to find button by touch, even without the clip, or just to press button.

Here’s how exactly the same button looks in the Nitecore P30i

And here’s how in the MH25S. No problem at all. The finger immediately hits the pad around the button. And you can press it effortlessly, even with gloves.




There is a type-c charging connector at the opposide side. The plug is thick and secure.

The charging current is good, little bit below 2A most of the time. So just 3 hours and your flashlight is ready again.

The bezel is not tactical at all with its baby teeth. But, well, that is better from the EDC standpoint. The reflector is medium in size, smooth. At the bottom, perhaps that there is no alternative now for such non-specialized models – SST40.




UI

You`ve got EDC and tactical line of modes. The difference is clearly shown in the picture below.

In general, a fairly common interface. The combination of the side and tail buttons allows us to make a more convenient interface (especially with an additional signal sleeve installed), but this one is quite suitable for both everyday and tactical needs.

Tail button:

From OFF:

Fully click: On
Half-press: Momentary on (Memory mode when in Daily mode – Turbo in Tactical mode)
From ON:

Fully click: Off

Side switch:

From ON:

One-click: Change modes upwards/downwards (dependent on Daily/Tactical mode)
Hold: Activates and cycles strobe modes:
Daily mode: Strobe – Beacon – SOS. Release the side button to choose your desired strobe. Press the side switch again to return to the last-used mode.
Tactical mode: Strobe only. Press the side switch again to return to the last-used mode.

Mode memory:
there is mode memory in Daily mode

Low voltage warning:
When the battery below 50%, the power indicator on the mode switch will flash every 2 seconds. When the battery discharge is deeper, it will blink much more often.

Strobe/blinkies
You can access Strobe in both Daily and Tactical modes, and Beacon or SOS in Daily mode only. This is done by holding the mode switch while the light is on for 2 seconds.

HOW NITECORE MH25S ILLUMINATES

The flashlight has a decent runtime. Stabilization is imperfect only on the chart. Live brightness will be quite on the same level. Separately, it is worth noting the good runtime of the turbo mode, which, when cooled, allows you to work for a very long time at close to maximum brightness. Overall, i like how Nitecore MH25S performs in matter of runtime.

The light is cold white, as u may expect. It is not critical for this kind of flashlights which shouldnt give you colossal range. But CW is definetely not what advanced users are glad to see.

The average user will see that the Nitecore MH25S gives a comfortable light at a medium distance, which, due to a decent maximum brightness, will be enough for almost all needs within a couple of hundred meters. When working at very close distances, this flashlight will definitely be less convenient than the classic pocket models with a textured reflector. But not inconvenient. There is a definite difference between “inconvenient” and “others will be more convenient,” the main thing is to grasp it.

The flashlight is quite usual in terms of range or brightness. For modern standarts of what we now consider to call bright flashlight, of course. As is, flashlight is really bright. This is a pure workhorse for a wide range of ordinary needs, and its light and modes spacing will be enough to cope with them.





and some Nitecore MH25S beamshots to illustrate it`s throw abilities. they are quie good, btw.



Video review of Nitecore MH25S contains way more examples of how it illuminates.

OVERALL IMPRESSIONS

If we ignore the price, which puzzled me, being at the level of some top models, Nitecore MH25S showed everything that this model was famous for in the MH line. The flashlight is versatile in the best sense of the word. It can be used as an EDC, and quite as a tactician. Of course, specialized lights of each type will be more convenient, but the MH25S does not leave the feeling of some kind of ersatz handicraft.

As I said above, there are no exorbitant brightness or range. Light is good for mid-range works, exactly the distance most demanded for most users. I am inclined to believe that CW will repell experiensed users. After a certain number of flashlights and the ability to compare CW even with 5000K, cold light often causes a fair amount of antipathy. But the average user will appreciate the fast charging and the goood runtime both in general modes and in turbo, which becomes excellent with some cooling (what you normally get in outdoor use). The flashlight easily sustains the level that was the maximum for the initial version. And the complete battery is more than twice as capacious as at the time of the release of the first MH25S. Moreover, such a 5000mah battery will charge faster.

UI is simple in a good way and although the side button is small here, there are no problems with access to it. I would prefer some other UI, but I honestly evaluate my professional deformation and understand what it is as it will be optimal for most ordinary users.

I’ll tell you straight – evaluating Nitecore MH25S both as part of the overall development of this model line, and as flashlights solely, I’m ready to put a solid “good” mark. “Excellent” would require neutral light and more flexible control. Unfortunately, the current price confuses me. I hope that when Nitecore MH25S will loose “novelty” status, it will also lose in price, which will now scare off a fair number of potential buyers.

Functionally, I repeat, it gave everything that I expected from it, and in something (runtime in a turbo and charge speed) even surpassed.
