A lot of torches of the “next-generation” come (and will come in future) with a powerful XHP70 LED built-in. Because there’s only one 26650-cell needed, these lights are pocked-sized. So it’s possible now to have 3000 lumens in your pocket. The Acebeam EC50 GEN II is one of this generation; in this review we have a closer look at this compact power-light, also side by side to another torch in the same output-class. Of course, we also go outside with both ones, to see how they perform. Let’s kick off!

the second generation of the Acebeam EC50

Unboxing:

Like we are used of, Acebeam always takes good care about the package. The EC50 Gen II arrives in a sturdy light-brown box. Personally, I like these boxes, because it’s easy to restore the light and you can open the package without tearing the carton. At the box some prints and specialties about the light in black and orange color. Inside it looks neat: Branded sachets for the spare parts and lanyard, a gold-plated USB-charging-cable and a plastic warranty-card. The box is ready-to-go: Only thing we need is a charger or USB-port to charge the EC50 Gen II. So, again a nice and complete package here. I took some pictures of the box and the contents, please scroll down!

Impressions:

The Acebeam EC50 Gen II is a mid-sized torch that has a relative thick tube because of its power source, a 26650-cell. But daily carrying this light in your coat pocket should not give any problem, it’s easy to carry. Personally I like the looks of the EC50 Gen II: The knurling, the fins and the bezel give the light powerful looks. The light is in deep-black color and is built and finished very well. No defects found on the anodizing, and the laser-engraving is clear and well-done. In contrast to the first batches my EC50 has a different print below the power-button, in the same tint as the button and the bezel. The micro-USB charging port is protected by a rubber cover. That cover closes properly, because when you remove it, a “pop” is heard. I hope it will last for years, Acebeam doesn’t provide a spare-one in the package. I’m happy with the good anti-rolling design of this one. Looking into the lights’ head we see an orange-peel reflector (I detected a tiny spot in the reflector) and a well-centered XHP70 LED. Looking into a reflector that has a “four-in-one” LED shows (for your eyes only) a typical bloom-shape. During releasing the cap I noticed that the threads run smooth and are lubed well. Striking detail is the red O-ring, I saw this earlier at…. the Nitecore TM03. No glue or solder rests in the cap or tube, Acebeam really takes care about the finishing. Let’s have a look at a couple of pictures below, that show more impressions and details!

User interface:

The EC50 Gen II has a compact shape, a rather thick tube but fits therefore good in a man’s hand. The head that has a lot of cooling-fins and the knurling protect in a proper way against accidentally slipping out of your hand. The light is not too heavy. Charging of the light is an easy job: plug in the micro-USB jack and connect it to a cell-phone charger or anything like that. The indicator is not that bright, but will inform you about the progress. Keep in mind that a big 26650-cell needs a longer charging-time.

All modes and functions of the EC50 Gen II are controlled by the same power button. Personally, this button is not my favorite: I would have seen a button that needs a firmer press and with a stiff structure. With this button, there’s the risk of accidentally-on, and during cycling through the modes I picked regularly the wrong one because of the “week feels” of the button. So, I hope that Acebeam will bring back the rubber on a next version….

The operation of the EC50 Gen II is not a difficult one: Press of on and off, the light will start in memorized mode, except Turbo or Strobe. Press and hold the button to cycle through the four normal modes. The Turbo mode is an instant-one: two quick clicks (both from on or off) will enter the highest output. Three quick clicks will bring you in Strobe. Those modes (Turbo and Strobe) are locked: this means that you can’t cycle to another desired mode, you first have to shut off the light. The EC50 Gen II has also instant-Firefly mode; this mode can only be activated from off. Press and hold the button to activate. In contrast to the other direct-modes, you can go to the other normal modes out of Firefly. You can lock and unlock the light by pressing and holding the switch for more than 3 seconds, and is indicated by three slow flashes. The torch has a built-in overheat protection, this is needed on a light like this, it gets really hot in a few minutes.

Modes:

The EC50 Gen II has in total five normal output modes, in order of: FIREFLY > LOW > MID > HIGH > TURBO. Except the lack of a mode between 1 and 80 lumens the spacing is good. Three instant/ special modes: direct-FIREFLY, instant-TURBO and instant-STROBE. Two ways to LOCK-OUT the light: by pressing and holding the button and by releasing the cap a little. Overall, I’m satisfied about the modes the EC50 Gen II offers, especially the instant-FIREFLY and TURBO.

Size comparison:

A comparison here to another light in the same lumen-class and also powered by the powerful XHP70 LED, the Nitecore TM03.

Tint:

I was little surprised by the tint of the EC50 Gen II. It seems more neutral than cool-white, especially when its shown against the little bluish Nitecore TM03. Personally, I’m happy with this tint.

Beamprofile:

A mixed profile here: big spot and corona, little spill. Not an impressive thrower, but the EC50 Gen II emits a wall of light. It’s a clean beam, no rings or defects visible. Neither PWM detected at any mode, so the beam and the profile is ok to me.

Beamshots:

Let’s have a look now how the EC50 Gen II performs! Starting by projecting the light at a white wall, distance about 0,75 meters.

Camera-settings: ISO100, F/2.7, WB daylight, 1/125 sec, 35mm

The second location is a road with trees at left and a dam at right side. The Nitecore has better throw, the EC50 Gen II a nicer beam and better color rendering.

Conclusion:

At the end of this review I can tell you my overall impression of this light is a good one. It is a well-built and finished light, is rather compact, so daily carrying doesn’t require that much effort. Charging is an easy job, and the light comes including a cell, so you’re ready to go. It produces a clean and nice mixed beam that has a good tint too. The Turbo mode is a nice feature to impress and for quick search, but will not last for that long; for longer jobs the High-mode is the better option, also because it drains the cell quickly. So a good point in my opinion that Turbo is an instant and separate mode.

Main issue to me that I want to see improved is the power button. I would like to see a (illuminated) rubber switch that better grip and pressure point.

But I can recommend the EC50 Gen II: it emits a wall of nice light!

Special thanks to Acebeam that I could enter to the Global Test Campaign!

High mode for Nitecore TM03 is 1350lms for 45min and for Acebeam 1500lms for 2hrs. Quite a difference.

Great review/pics as always, love the beam pics............to me the ec50 II is perfect! Nice wall of light and the cool(ish) tint looks good too, better than the tm03 anyway(to me).

Thanks for the great review kj75.
Sorry, just to clear it up for me, the normal operation is, firefly-low-mid-high, with access to turbo being a quick double click from any of the normal outputs, or is it firefly-low-mid-high-turbo repeating ??
Many thanks,
Mike.

Sounds like turbo is not part of the cycle. And sounds like the only way to exit turbo is turn off the light. Please correct me if I'm wrong.

That's correct. Also, if you access moonlight by a long press from off, it is not memorized unlike when you activate it by cycling.

The answer is given by @Maukka already, thanks!

To me, not a big problem if turbo isn't part of the cycle, because I use that mode can't be used for long time

Great review!

I too would like to see a small LED beacon under the power button or next to it. Side click lights need some help if you need to find the button in the dark quickly.

The Nitecore has a larger, deeper reflector and much less spill/flood in the beam than the Acebeam. But when you look at the distant trees in the beamshots, there doesn't seem to be any difference between the Acebeam and Nitecore. Why is this? I would have expected the Nitecore to light up the distant trees a lot more than the Acebeam. Maybe the pictures aren't showing the extra throw of the Nitecore?

I own a TN4A NW XP-L V6 (orange peel reflector) with a peak beam intensity of around 26k. Acebeam's EC 50 gen 2 peak beam intensity is around the 23k mark, however Acebeam's beam profile looks much more pleasing to my eye (going by the review photos) with it's indistinct hotspot.

I do not quite like the tight hotspot of the TN4A, and although it's a very nice light I would have bought a floody light had I known about beam profiles earlier on. I have placed a circular wax paper to cover just the lens and now it's a 120 degree flood much to my liking (albeit at a cost of some lumens lost.)

The question I intend to ask is how come with approximately the same CD rating the beam profile of these lights so different? Does the 3 times higher lumen output of the Acebeam come into play?

my sample of EC50 has about 140 houndred CD. The difference with the tn4a are on the emitter size (the lower size, the more intensity), the bigger diameter of tn4a (more intensity). So they have not the same throw nor the same beam type.

Thanks for review! I like tailstandable single cell lights. I guess turbomode is a few minutes and then a drop to high mode like usual with single cell high output lights. But high mode of 1500lm is more useful and while 2hours probably is not available 1,5hours may be possible.

And I like that firefly and turbomode are excluded from the memory!

Was able to try out an EC50 GENII and I loved everything about the light except the switch.

Hopefully the GENIII addresses this, but until then I'll [sadly] have to pass.
