[Review] Acebeam L17 ultra long throw tactical flashlight

I reviewed my first Acebeam 4 years ago and since then I don’t remember being disappointed by any their model that had chance to review. In terms of the number of experiments and the implementation of any innovative solutions, only Nitecore can surpass them. But Acebeam’s trump card is not the number itsel, but final convenience of use and product logic.

I have already dealt with two Acebeam long-throwers – T21 in the classic 2×18650 form and the monstrous Acebeam K75. Each of them stepped over 1 km throw, which is crazy.

Acebeam L17 model does not reach a kilometer, but no one who see L17 will imagine that such a compact model can give such a penetrating light.

The model was created not for a wide audience, but for hunters and special forces. If you belong to one (or both) of these categories, I hope you find this review helpful.

or from Nitetorch.com here

PACKAGE AND APPEARANCE

Black box with only green and white versions mentioned, it lacks red one.

There is a pad with everything you need inside it. Set includes: Acebeam L17 flashlight, tiny packet with a lanyard and O-rings, nice holster, manual and warranty card. The battery (+ charging cable) and the remote button are sold separately.

This flashlight is far from being high-design. Well, that is normal for tactical models. The design is quite simple and doesnt look that agressive as lots of tactical models do.

Nevertheless, it is immediately clear that it is a branded model, not some noname or budget model. The matte anodizing is just what you need for a sleek case. It is a pity that they do not do the carbon texture, it would look and feel super.



L17 is smaller than its popular budget rival, Sofirn C8G which has 250m less throw being like 30% brighter.

Unlike the previous version, L17 has only tailbutton. It moves softly and completely silently

There are, of course, two springs at the side of the head and at the side of the tail.

The thread is perfectly lubricated with two O-rings.

An additional sleeve is pressed into the primary flashlight body, to transmit a signal from the tail button.

flat-top battteries need a magnet spacer to be used with Acebeam L17. And if you take into account the recoil from the gun, then I would recommend avoiding them. It is better to take button top batttery.

The battery, by the way, is not cheap and simple – it has a built-in charge! The charging current is good, 1A.


The tactical stop ring and clip can be removed, but the flashlight looks like naked without them.

As I mentioned, there is no usual knurling. The body is smooth and is decorated with only 2 cheeks with the model name.

Nevertheless, due to the clip and the stop ring, the grip is quite good.

The head is medium in size. Cooling fins are deep, but not numerous.

The bezel is the usual sort for tactical flashlights. there is a thread for the filter inside. Taking into account that L17 has also green and red light, and this model that requires no filter, i assume that this bezel is taken from any previous model.



Bezel is glued, so it was not possible to look inside the head. It’s a pity, there is the most interesting Carclo optics, which I have not seen anywhere else at all and which I would love to look at closer.






That’s all. Good looking flashlight with no visible manufacturing flaws. However, I wouldn’t expect them from Acebeam at all.

UI

I`m not sure that that with such a UI Acebeam L17 will be convenient when gun mounted without remote button. The combination of a side button and a rear one would definitely be better for hunting.

How Acebeam L17 Illuminates

All three color options are different in brightness (at least red one from green and white), then the light distribution here is exactly the same – no side fill with the brightest center.


The promo picture promises full stabilization, and yes, Acebeam L17 has it. The runtime is quite decent. However, I would prefer L17 to store 21700 battery.
Flashlight get really hot in turbo mode, after couple of minutes you simply cannot hold it barehand.


As for the light itself, everything is super. If you turn on the flashlight in dusty air, then from the side it will look like you are holding a real Jedi sword or laser gun. L17 has astonishing penetrating power.

Flashlight penetrates 100 meters without any problems even even in Low mode. Of course, due to optics that cut off all the sidelight, review of Acebeam L17 shows that it is likely to be pretty useless in everyday life and in many situation when you need work between 50 and 100 meters. But if u need you need to illuminate as far as possible, without some crazy brightness – this is what you need. There are models with better throw, but they are definitely larger. And those that are smaller are closer are damn expensive and are closer to laser.












And here is full video review of Acebeam L17 as well. I appreciate if you subscribe my channel, i just created it and need really need more subscribers

Overall impressions

I`m not hunter, so i will not evaluate how good is L17 for hunting. (here my experience is limited to duck hunt in dendy). But apart from this, after making review, Acebeam L17,overall, is a nice model. It is quite compact and surprisingly affordable. It might cost way for as the new model if had another brand name.

And with its moderate size, it has a throw that would require a significantly larger head size and / or significantly greater brightness. Any classical reflector\XHP35-XPL-Hi model with the same brightness and size have so much less throw.

Overall, this flashlight is specific, but it does what it supposed to to – to shine extremely far.

+ beam color choice
+ appearance
+ high quality Acebeam workmanship
+ convenient (not the fact that for hunting) one-button UI
+ full stabilization
+ price

at the moment, no CONs come to mind. May be side button as of L16 would be better, and 21700 would definitely be better rather than 18650 . But i dont have any problems with Acebeam L17 as is.

Did you record throw numbers for the green version? I got 694m for the white on turbo. Not 802m they claim, but not bad anyway for no reflector! If they went with the Boost HX not the W2 I think it would have cracked 750m. Maybe in a version 2.0?

I concur! at that price with Acebeams quality this light is hard to pass up Thumbs Up I really do enjoy your reviews. Reading reviews is like any other left with imagination but when you add your visuals it really shows what a flashlight is capable of for me. They help me decide on what flashlights I want and would like. As always Lumeniac, great review. Thank you for taking the time to do so Big Smile

It is a great value for sure and yah it even though doesn’t throw 802 m, it still throws way farther than any similar sized (unmodified) reflector light. It’s a roughly 39 mm optic throwing 700 m. It’s not W1 either. Pretty good in my book. Plus 5 year warranty to boot.

I got one of these off of Amazon, pretty amazing for the size. Think back a few years, a light with this much throw was a shaved XPG2 in a huge reflector or an aspheric, all custom built. Now, for less money and time, in two days you can get a light like this delivered, and the battery has built in charging to boot!

I have to say, Acebeam lights are pretty well built and I would get the pressure switch for this light if I had a need to mount it to a firearm. Even on the 350 Lumen “High” it throws pretty well. Turbo is just nuts on a light this size. I cannot wait to try it out against the Manker MC13.

nope, i stopped all this measurings like 3 years ago

 

uu just move hotspot soke millimeters off center ans get other numbers, found it useless, as much as bounce test - it showed different data for different reflectors

 

i wish i had integration shpere, ready to spend  big nucks on it - but no place to buy, and 'pipe' variant is not also universal

 

i am trying to say that i have no doubts in Acebeam specs, they are also pretty honest in this

as far as i remember , only once they simply didnt mentioned stepdown in turbo and that's it

Thanks for the nice review, Lumeniac!

Unfortunately, I cannot see any pictures in your review. Both cellular and wireless network do not load any pictures here. Sad

Привет, Люмениак

Thanks for your quick response. I still cannot see any pictures on this thread on BLF but I see them on your review on ixbt.com.

Did you check your sample for the "low voltage bug" when the battery is depleted to less than 3.3V? Maukka's and mine would not work properly as moonlight does not work anymore. Instead, the light blinks two times and then returns to a standard mode of low, medium or high.

Here's what maukka wrote: "After the light has blinked three times to indicate a low battery (this happens <3.3V), the lockout doesn’t work from off with a 3 second press. The light just flashes a couple of times and after a while it stays on and locks permanently on until you unlock with another 5 second press. Secondly, the ultra low mode access from off doesn’t work correctly. The light first turns on at a higher mode and only then turns down."

bitte schon (meine kayboard habe keine umlauten)

i checked this review from wife`s laptop - everything is cool

for example

https://www.acebeam.com/Images/uploaded/L17/L17-10.jpg

can you open it separately?

 

try to open it from another devices. links here are directly from ixbt or from Acebeam website

 

i willl check it later, ehh, had to read these reviews more precisely

 

nevertheless, dont think this is a real problem as normally you will switch to new battery once another one is discharged that much

Output measured at 2 seconds from turn on using Texas Ace Lumen Tube calibrated with Maukka lights. Color measured using Sekonic C-800-U.

Acebeam L17 Turbo 1,141 lumens 7110K -0.0042 DUV 70.7 CRI Blue light relative amplitude 1.00 -12.6 R9 42.2 R12 64 Rf 96 Rg VTC5D
Acebeam L17 High 293 lumens 6200K 0.0037 DUV 66.9 CRI Blue light relative amplitude 1.00 -36.9 R9 36.3 R12 63 Rf 95 Rg VTC5D
Acebeam L17 Mid 131 lumens 6012K 0.0056 DUV 67.0 CRI Blue light relative amplitude 1.00 -39.9 R9 34.9 R12 64 Rf 94 Rg VTC5D
Acebeam L17 Low 40 lumens 5769K 0.0081 DUV 66.9 CRI Blue light relative amplitude 1.00 -45.0 R9 33.0 R12 65 Rf 93 Rg VTC5D
Acebeam L17 Moonlight 9 lumens 5403K 0.0109 DUV 66.5 CRI Blue light relative amplitude 1.00 -49.2 R9 31.2 R12 66 Rf 92 Rg VTC5D


The light is huge for an 18650. It is larger than most 21700 lights. For this size, I don't understand why Acebeam didn't just make it a 21700 light? I like how with this optic, the spill gets dispersed evenly so the hotspot stands out more than from a reflector light.

i suppose that using tube is not precise for such spcspecific light destribution

 

aall your measurements are far away from spec

s

in 9/10 situations, when manufacturer lies about brightness, that is about turbo. the rest modes correspond with specs, as there is no use to lie about low mode, which any flashlight can produse

 

that is why i stopped using both bounce test and pipe, as soon as u get flashlight with other light distribution, measurements go wrong

 

such specific measurements requires integration sphere

The Lumen tube has been pretty accurate. I measured hundreds of lights with it. My calibrations may be slightly on the low side but it is very consistent. For example, my measurements of this light is not much lower than Maukka’s measurements on this light. Maukka uses an expensive integrated sphere.

From my experience, only Olight and Fenix output ratings are consistently accurate or even conservative. Emisar and Fireflies are accurate for some but they don’t test all of their lights. All of the other flashlight brands including premium brands like Nitecore, Acebeam, Zebralight, Nitecore etc. rate their output 15% to 25% higher than what I measure.

Acebeam rates turbo at 1400 lumens and your figures show 1141 lumens which is about 18% less.  Since it takes about a 400% rise in lumens to perceive about twice the visible brightness to the human eye, 18% is not a deal breaker  but good to still know the manufactures are stretching their specs a little and to always  keep them  in check.

Also keep in mind my numbers are measured at 2sec after turn on. At 30s it will drop lower. Only Fenix and Olight measures at 30s.

Would be interesting if you had the 30s numbers as max lumens at turn on is not very realistic really for any practical use except for manufactures to bloat a little about their numbers.

Not a bad review for a “TactiCOOL” light.

As I’ve said many times any light with an E-lock out is not safe for real tactical use. This takes 5 seconds to get into the fight, if accidently locked. Sorry AceBeam.

Read again! “As I’ve said many times any light with an E-lock out is not safe for real tactical use. This takes 5 seconds to get into the fight, if accidently locked. Sorry AceBeam.

You don’t have 1 second 2 seconds 3 seconds 4 seconds 5 seconds in a fight for your life, to be fumbling around with a light.

In NJ it’s THE weapon of choice for most law abiding people. It’s one of the only things you’re allowed to carry.

I don't think it's against BLF rules, though I try not to hotlink because the image I hotlink to can be taken down at any time.

really, not against the rules to hotlink.. hmmm.. ok

does your computer show images in post #1?

this is what I see as the first image in post #1 (a broken image).. do you see an image here?:

for my computer
the image code needs to look like this (intentionally broken link for nettiquette reasons)

note that link is a direct hotling to the acebeam.com website
are you sure thats not against the rules?
this article says hotlinking is bad

and this cool dude says to use a hosting site:

IMAGE HOSTING

You have to host your images on an image hosting site before they can be posted on BLF.


so, Im going to break my hotlink…

anyway, really cool flashlight.. I especially like the green beam version
