[Review] Acebeam W30 LEP 21700 flashlight

Hi there,

I had the chance to take a look at Acebeam's latest flashlight, the W30 LEP flashlight. This sample here is a passaround item courtesy by Mr. Sven Stewitsch (www.stewitsch.de), being reviewed by a couple of TLF members. I did not receive any compensation for this honest and unbiased review. If you want to read the German version, please click ► here ◄.

Acebeam's W30 is - like its little predecessor W10 - a LEP flashlight. LEP is the abbreviation for "Laser Excited Phosphor". To explain it in simple words: LEP is a high yield energy laser (mostly with short wavelength in the blue spectrum) that is being deflected by a mirror/optic onto a phosphor layer (similar to those of classic LEDs). Once the laser beam hits the phosphor layer it will be excited, i.e. it emits white light which is then being focussed by a convex lens to achieve a maximum intensity (= high range). The benefit compared to classic LED flashlights with LED and reflector is a much more focussed beam that achieves incredible 1.45 million cd (equals to 2.4km of ANSI range) with a head diameter of only 61mm.

Appropriate safety precautions are indispensible when using a flashlight like this one.

Acebeam's W30 is ranked as follows i.a.w. IEC 60825-1:2014:
Maximum output power: 12W
Wavelength: 500nm - 650nm
Laser warning class: 2M

Some specs about the Acebeam W30

Packaging and content:

Apparently, there will be more variants of the W30. But it is worth discussing how reasonable a HighCRI version is for throwers and if this version will be as efficient and powerful as the LowCRI version. Usually, HighCRI LEDs are much less efficient compared to their LowCRI counterpart.

Size comparison:

Unfortunately, I didn't have access to my Acebeam T27 when I did the review. So, I used some other flashlights instead that were introduced in 2019, too.

A close-up look onto the W30

The light can be dismantled into three parts, head, battery tube and tailcap. The battery is protected against accidental activation and discharge during transport. There is a clearly visible warning sign attached to the light, telling you to not look into the beam. Moreover, there's a tripod socket as well as battery indicator light (not visible on the picture) that shines green when the battery has sufficient voltage. Threads are very well lubricated, so I had to clean the contact areas on the tube's ends to reduce contact resistance as much as possible. The tactical ring can be removed but first you would have to remove those two o-rings.

Acebeam uses a metal tailcap. This seem to look nice in terms of appearance but there's a risk of having lots of unpleasant scratches (some are already visible although brandnew from factory). Furthermore, I would prefer a black tailcap made of rubber as it would fit better to the entire matte-black flashlight. In terms of cloaking and for military/tactical purposes people would also prefer to have as less reflectible material as possible when using a flashlight. The tactile feeling of the switch is okay, i.e. not too cushy and not too stiff.

The tailcap PCB is fixed by screws. I assume that Acebeam did not decide to use spring bypasses or double-springs due to a low current consumption of about 3A.

A quite similar look is presented in the head unit. The driver appears to be held in position by a retaining ring which again is fixed by two screws. These screws seem to be glued to prevent any further dismantling. The retainer is in a raised position compared to the outer aluminum rim, i.e. cleaning the flashlight's head from abrasion will be more difficult than usual.

The glas lens is AR-coated. The inner rim of the bezel ring has threads to use the supplied red filter. A look into the front part reveals the inner structure of the LEP technology. You can see the convex lens, the mirror unit and the yellow phosphor layer. The supplied Acebeam 21700 battery has a microUSB port and a small LED next to the positive terminal to indicate its charging status while charging.


The W30 has the simplest user interface anyone can imagine: ON / OFF by pressing the tailclicky switch. There's nothing more to pay attention to. The light gets quite warm during long-term operation, mostly in its middle part. Unlike classic LED flashlights where the entire head unit becomes hot after a while the W30 only gets warm in its center area around the laser module. However, heat transfer is good and it never became uncomfortable even with ambient temperatures of 26°C.

Indoor beamshot comparison

From left to right: Convoy M3 (XHP70.2 N4-7A 3.000K), Acebeam W30 (LEP 6.500K), Sofirn C8G (XHP35 HI 6.500K).

The reflection of the W30's light beam was so intense that my eyes started to hurt. In order to get a useful image, I had to take an underexposed shot. Here you can see a very well-defined hotspot of the W30 with no spill whereas the M3 and C8G show the typical spill of reflector lights. The W30's CCT looked very neutral-white to me compared to the cold-white C8G, even though both lights have the same nominal CCT of 6.500K.

Outdoor beamshots

First of all I need to say, caused by physical factors, it's quite a challenge to take useful beamshots of LEP flashlights as the light hitting the sensor area of your camera is too far away. Moreover, there's no spill to illuminate your surrounding area. As a result, useful pictures can be better achieved with SLR/bridge-cameras and not by freehand-held smartphones, as can be clearly seen below. So, please excuse the poor quality of my pictures with colour noise and blurriness. I hope you still get a feeling of how the W30 looks like in operation.

With the W30 Acebeam has launched another impressive flashlight. Even though it has only 500 lumens far distance targets look brightly illuminated. Acebeam's target group is probably very small as LEP lights are not intended for mainstream purposes.

What I like about it:

  • If you are looking for the ultimate thrower at least possible size, the W30 is the best choice.
  • Workmanship and handling are very good, the accessories are extensive except for a holster.
  • The light colour is against expectations quite neutral and does not feel like cold-white 6.500K
  • The W30 will not get too hot, mostly due to its moderate power consumption

What I dislike about it:

  • The price is quite high with about 286,00 Euros. This may be due to its new technology, small sales numbers and the small target group Acebeam will hit with this product. So far, Acebeam has very few competition here except for Weltool with their W3.
  • Unlike with the T27 Acebeam does not include any holster with the W30.
  • The red filter lens is a nice add-on. However, you won't get very much (red) light into the distance with the filter attached to the light.
  • The retaining ring is in a raised position which makes it hard to get into the outer rim for cleaning the head unit. Moreover, Acebeam seems to take actions against modding as those screws appear to be glued.

Best regards,

I’m in a state of WOW looking at these beam shots. 2400 meters of throw in such a ‘roughly’ small package is absolutely crazy. I have the W10 and this W30 makes it look like a child’s toy in comparison. I can definitely relate to the intensity of the hotspot bounce back on the wall with the W10 and I can only imagine how much worse it is with the W30. Definitely wouldn’t want to be on the receiving end of this beam. Thanks for the review.

Thanks for the first review ever on this super impressive thrower. Do you have a lux meter to take throw measurements to see if it really throws as much as specified? Would also love to get some specs on the HI CRI version.

Thank you guys for your kind feedback.

I must admit I don’t have any lux meter (yet). But I’m pretty confident that some of the next reviewers in this passaround will post their measurements, at least on TLF. If I get to see any lux numbers I will try to post it here.

Concerning the HighCRI W30: I‘m not sure if and when it’s gonna happen. At least I hope they will be launching the 4000K version soon as its beam should cause less scattering than the 6500K version (see „rayleigh scattering“).

:+1: :beer:

Simply insane. Thanks for the review

Wow! Super awesome! But it is ugly looking flashlight though

That’s probably the only thrower that would benefit from having a smaller head/optic, the beam is too colimated to be usefull imho.

Imagine a 21700 tube sized flashlight with 500+ kcd throw, the first actual real pocket thrower.

Is this light only one mode?

Yes, one mode only by pressing the tail switch for ON and OFF.

This is one light where I’d have probably zero reason to ever actually use it… but I still want one. :laughing:

Well, I would be interested in this light if zoom/focus would be available and also some modes low/med/high - all these would make it a real sure in my case,other then that,the only use would be nighshooting for the actual settings

Nice mate! Thanks for the wonderful review!

Thanks for the review. Been wondering what that beam was going to look like . Thanks again .

Some pictures - don’t know if it’s OK to post here, rip it out mod’s if it’s not. I posted it on CPF because it’s easy to post pix in the forum using Tapatalk - BTW would it be too expensive to have BLF have access to Tapatalk? W30 pix

You should learn how to link images directly.

Huh? do you mean from where I posted them on CPF? because I just dropped the pictures into the tapatalk app on my phone, so there is nowhere to link directly.

It takes some finding out how to post pictures on BLF. But there’s a tutorial (link). In short, the pics should be hosted on a picture hosting site, you copy a URL directly referring to the picture, in the BLF editor click on the image icon, and paste the URL in the pop-op screen in which screen you can also choose at which size you want the picture to appear in your post.

Btw, your pictures are rather over-exposed in the hotspots, you can see the size difference of the hotspots of the BLF-GT and the Acebeam W30, but not the brightness difference.

Edit: my fault, I only looked at the two pictures that Blue re-posted, the full set on CPF provides a very nice comparison! :+1:

(pics from Glenn on CPF) BLF-GT / Acebeam W30, with 500mm zoomed camera.

W30 is clearly out-throwing the BLF GT. Wow! That beamshot could easily be mistaken for a shortarc light.

Yes I do know how to direct link pictures, but as you said they have to be uploaded somewhere on the web and mine aren’t, I have done and been able to do it since 2006 when I joined cpf, I just do it now through Tapatalk for ease and speed. And those two shots blue posted of mine weren’t the best to put here without the reference of the rest imo.
But thanks.
