Full review and comparison of Acebeam H30 — the brightest flashlight in the world.

In addition to 4000 lumens of maximum brightness, Acebeam shoved other interesting things into this new product: Type-C, power bank mode, 21700 power, two additional LEDs (optionally there is even a Hi-CRI version with Nichia). The price tag here is frankly rather big, but this forehead has everything.

I think that looking at the brightest browband will be interesting for those who, in general, are useless.

Packaging and appearance

The packaging is quite good. Thick walled cardboard box with good design. It is absolutely not a shame to give such a gift. The journey from China survived without damage, even in the absence of a pimply cocoon.

Available options are also indicated here: the headband can be with a cold / neutral light to choose from, and a pair of permanent red additional light can go: green XP-G3Nichia 276A 365nm UVNichia 219C HiCri

Inside, in a thick layer of foam rubber, the entire kit is neatly laid out: the Acebeam H30 itself, a 21700 battery, a charge-discharge cable, a head mount, o-rings, instructions and a warranty. The adapter to 18650 is also indicated on the box … but for some reason I don’t remember that it was there.

With such functionality, it would be problematic to make the forehead in the usual L-shape, so the T-shape here is an unambiguous choice for the design. Yes, and from the standpoint of heat dissipation, this is also a clear plus.

Of those that deserve special attention, I will single out:

an unusual charging cord that allows the headband to work in power bank mode. In principle, an ordinary cheap otg cable with a type-c micro-USB adapter should perform all the same functions.

Proprietary 21700 battery

The headband is excellent, with reflective elements on the outside and a gel snake on the inside. The father-in-law just dropped in to visit, tested it on the test. I note that he is slightly below average in height, with appropriate proportions. On someone oversized, the forehead will look clearly smaller.

For a couple of weeks that I had a forehead before writing a review, I made quite clear impressions of convenience. Of course, the headband is far from the same skilhunt H03 in terms of weight and dimensions, but I don’t have the feeling that it is excessively heavy. The difference here is real only in comparison, and with the correct setting of the head mount, the Acebeam H30 does not burden the head. However, maybe if you use it all night, you can feel uncomfortable. Or maybe not … it’s all subjective.

Well, this is how the Acebeam H30 looks like. Due to the form factor, it is definitely shorter than the Skilhunt H03, but the Acebeam H30 compensates for this difference with a hefty protrusion in the center. Since the skill is ubiquitous and widely known, in the future it is this model that I will use as a control sample.

In general, I liked the look. The design is somewhat heavy, but quite suitable for my taste, and the browband, for my taste, is far from the curvy, angular puff, which could easily be made in such a form factor and dimensions.

But from the unusual for me — two tailcaps. One, as usual, hides the battery compartment, the second charging connector.

Both springs, of course, with such and such currents. very thick.

The thread is generously smeared, there is also a charging connector, which is closed from the side of the end of the headband with a translucent plastic plug with indicators hidden under it. They are ordinary: red is the charging process, green is its end. Blue — work in the external power bank mode.

In this view, you can clearly see how deep the cooling fins are. The knurling on the tail caps is quite fine, just the latter itself is thin (only 1.2mm, including the thread). On the other hand, if the thread is large and smeared, then there is no special question for this. I had no difficulty with twisting-twisting the tailcap.

From the front, like some other headbands, Acebeam H30 is very reminiscent of a physiognomy

The reflector is textured, with XHP70.2 on the bottom. On the sides there is one additional LED, the latter can be selected.

The front part twists without effort. Everything here looks decent, without dirt and other things.

That, in fact, is all about the appearance of the forehead. Outwardly, he looked to me, for a couple of weeks of periodic use, I did not feel any inconvenience in wearing it.


Convenient good management.

How Acebeam H30 shines

I got the version with cold light, but you can choose neutral. You shouldn’t expect high-crissivity and other things from the XHP70.2, the trump card of this model is its high brightness.

If you want beautiful light, take other headbands with lower brightness. It’s either this or that.

Light distribution Quite convenient for close use. The LED is definitely large for such a reflector, especially textured, so the light is quite blurry. Well, if the equipment with hi-cree is chosen, then there is generally expanse for the dipped-dipped beam, additional LEDs are quite bright here. I think that in this case it would be possible to hang a couple of brightness levels on a draw.

Chargingpower bank mode

Here the browband showed its best side — it charges quickly, gives no worse.

In PB mode, the headband gives 2500mah. The voltage sags, but I think that a good current compensates for this. I twisted the load almost to zero, the voltage did not rise above 5 volts. When work in this mode stops, the voltage on the battery is 3.2V.

I can’t help but notice a strange moment. The declared capacity is 5000mah, while I have not seen more than 4100. BUT! I have an alien Litokalov 21700 bank, bought out of curiosity for 3-4 dollars, with a capacity of about 4200mah. And there is a 5000mah Fitorchevsky acc (the tester shows this capacity somewhere). So — I tested all three batteries, and the graph from the complete one is quite comparable to Fitorchev’s. But the graph from the lithocal is much shorter. I don’t have any explanation, do you have any? I did about a dozen tests in different modes and then each time I charged the acc with the tester, I did not see more than the numbers indicated above.

Be that as it may, if the duration of the work is what it should be, it’s good.

currents 0.017-0.3-0.56-2-4.3A

it was not possible to measure the max current in the turbo, the thickness of the probes is not the same.

Well, here they are, the graphics. It is clear that with such dimensions, the issue of heat removal is very, very important and is directly related to thermal stabilization. And then the forehead showed itself from the excellent side, the stabilization is good, without a “saw”. Damn, yes, 1000-odd high lumes are completely stabilized. And this is not always seen in an ordinary flashlight.

By the way, by the way — the declared time of work diverges from the real one. Usually this is not in favor of the latter, but not here.

In turbo, max is +1 minute to the already not small three with the declared one and a half.

In a conventional turbo, even more, almost 20 minutes against 5.5. When cooling (regular USB fan) There is no brightness drop at all.

The only explanation that comes to my mind is that when they tested it in the sphere, the headband heated the air around in a closed volume, the thermoregulation worked earlier.

In short, with such a cardinal discrepancy, I tested several times, with different batteries — the result was without the same

It is clear that at such and such a brightness, the heating should be more than significant and, yes, the headband heats up quite well in turbo-max.

It warms up quickly and to an absolutely uncomfortable temperature. And here the question is logical, will the brains boil when working in a headband on a turbo-turbo max? Heating, of course, is felt, but nothing more, it’s just slightly felt, while you can’t take the carcass in your hands, it’s really very hot. Still, a layer of elastic fastening (especially not solid) and the very fabric of the head fastening makes itself felt.

Well, the most interesting, live examples of the work of the forehead

As I wrote above, the reflector is small quite usual for a headband size, the more it is small compared to such a large LED as XHP70.2. So the light here is quite suitable for close work. Well, due to the brightness that is crazy for a headlamp, it gives good illumination into the distance. Of course good for a nalobnik — a lot of much less bright conventional flashlights with a smooth reflector can continue to hit, of course, with radically, radically worse side illumination. And she is here very, very good when working at high brightness.

A rare case when I decided to direct the light on the windows, but the example was worth it. I am sure that at 8 pm 2-3 seconds of light brought even the slightest discomfort to someone.

Green and red The light here is very bright, especially green. In the open air within 5-7 meters, the brightness is already of little use, but it is worth reducing the volume a little, as the situation improves, see photos in the garage below. However, I don’t think that the specifics of using such light in a headlamp implies the need for range, this radius is quite enough here. Moreover, I think that they are so bright that it could be done using an additional mode. Even if the red light does not disturb night vision, but 50 lumens is too much, it would be possible to make an additional 5 lumens there + an instant start in this mode.

and the main light


for work at this distance, the headband is completely redundant, only full stabilization at high can bribe, which provides two and a half hours of work with excellent brightness. Having stocked up with one more battery, you can count on a remarkable duration of work, for example, during some work from evening darkness to “time for dinner and on the side”.


Somewhere the same distance. It is necessary to slightly reduce the dispersion of light in the open air, as the headband begins to impress even more. To be fair, it’s hard for me to imagine any specifics of working with a headband in order to highlight such large volumes of spaces. Well, mb speleology, but as far as I understand, it can be inconvenient in skinners with such an overall headband.

Skill n03 looks pretty good at maximum brightness, comparable to high in Acebeam H03, but with skill it will drop noticeably quickly, while acebeam will work at the same brightness without changes.

14th floor

I would estimate the useful range limit for the Turbo MAX to be around 100 meters — exceptionally good for a headlamp and quite normal for a regular flashlight. The headband compensates for this not the most impressive range by working in areas, highlighting everything around in this mode.

There is even more material in the video, traditionally.

General impressions

The race for lumens until some point bypassed headlamps, which for the most part are not brighter than 1000 lumens. This is understandable — basically, headbands are needed at a distance where this brightness is more than enough, and in general, something much smaller is needed. And here you can already play with some other variables — optics, color, harekrishness, built-in charging, etc. And here is a real expanse and a wealth of choice.

But for someone due to functional needs, for someone due to show-off or simple curiosity and / or the ability to satisfy it, it will be interesting to try their luck with something radically brighter and there is actually no choice of models.

In general, I think that Acebeam has rolled out a peculiar, but, in my opinion, a successful model. Acebeam H30 is not devoid of non-critical disadvantages associated only with the lower modes. And even as it is, it is quite functional. Well, I think that only the weight can confuse someone.

I suppose that in the absence of competitors with similar parameters / functionality, buyers would have to turn a blind eye to more serious disadvantages than too bright ultralow and the abyss between it and LOW. The latter, however, is partially solved by choosing a model with Nichia HiCri, which has a normal intermediate brightness and good color-light.

For the vast majority of users, both the price and brightness will be excessive, there is nothing surprising here.

In general, who knows, maybe in a couple of years the price of headlamps similar in terms of exhaust will be at the level of a third of this, in the end, not so long ago, the threshold of normal-quality flashlights with a brightness of 1000+ lumens was almost at the price of this headlamp.

+ appearance

+ constructive (as far as I can tell)

+ brightness

+ control

+ stabilization and thermoregulation

+ Type-C fast charging and external battery mode

+ possibility to choose between CWNW main LED and side LED options

— a gap between 3-120 regimes, the absence of something under the camp.

— ultralow is too bright, after all, something like 0.5 is needed here

— for side diodes, I would also make 2 brightness levels

— price. but there is nothing to be surprised. probably a small circulation + lack of pressure from competitive models allow you to raise the price.

— weight and dimensions

If this flashlight is out of your budget, look at wurkkos HD20
