Amutorch AT40 Flashlight Review

This is a review I’ve been putting off for months now (literally – I received this light way back in July).  This is a new light by Amutorch, sold by BangGood, using 18650s and emitting with Cree XP-G3’s.

Read on for more!  This is a review you’ll probably enjoy!

Official Specs and Features


There’s a quad version with Nichia 219c, which is a muleish aspheric.  And there’s the version I have, which is a 2-up Cree XP-G3 with tiny reflectors.

Price and Coupon

The price is currently $36.99 at BangGood.  Please click that link.  But please don’t buy this light.

Short Review

The light didn’t work.  BangGood didn’t ship a replacement, but they said they’d send a replacement driver.  BangGood never sent a replacement driver.

But hey, they host is pretty nice, if you can get over the mismatch between the head and bezel, body, and pill area.

  • Amutorch AT40
  • Spare o-ring
  • Spare switch cover
  • Manual


Package and Manual

Package is a cardboard box with an Amutorch sticker.



Honestly I forgot to get any shots of the manual.  It does not seem to be available at BangGood, either.

Build Quality and Disassembly

Generally speaking, this light is well (if strangely) built.  The body is titanium alloy which is a nonspecific way to say that some part of the metal is titanium.  All negativity about the ambiguity aside, I really like the finish of the body of the AT40.  The metal is pleasant to hold and use.



Unfortunately that’s where my like for the metal ends – I can’t get behind the difference in all the parts.  The body is the “right” finish, but the head is a matte, mismatched finish, while the bezel and tail are both shiny (just almost matching the body).

The switch is mechanical, and very easy to access.  The tailcap just unscrews right off – no threadlock is seen anywhere in this light.  There’s no spring on the tail end, either.  I did need to remove the pocket clip (two allen screws) to unscrew the tailcap, because otherwise the leverage applies uneven force.  But the clip removes easily.


The threads are quite nice and beefy square cut threads, with an adequate amount of lube.


Size and Comps

Officially 100mm long, 24mm in diameter (tail), 27.8mm (head).



Retention and Carry

There’s a pocket clip included with, and attached to the light.  It’s a steel clip (not stainless, at least not the non-magnetic kind).  The clip is held on by two allen screws, and is easily removable.  It’s worth while to remove the clip just to see how little clearance there is for the screw holes, and the bottom edge of the tailcap.  Much less than 1mm.  But it holds well, of course.  Strange that on an otherwise fully titanium [alloy] light, there’s a steel clip.  ¯\_(ツ)_/¯  Titanium clips are available, and wonderful, and would have been a nice touch.


Power and Runtime

The AT40 is powered by a single 18650 cell.  There’s a spring on the head end, and just a thin broad brass button on the tail.  Any type 18650 should work fine.


Unfortunately that’s where the fun for this light ends.  My copy did not work.  So I have no runtimes, no testing, no nothing else.  Just thoughts about the body.

User Interface and Operation

The switch is a mechanical tail clicky.  As my copy did not work, I can not say anything else about the UI.  And you can read the product page on your own time….


Here’s an empty UI table, where the UI table for a working light would normally be.

State Action Result
Off Click ¯\_(ツ)_/¯

Modes and Currents

The modes and currents table is here.  It’s empty because my sample light did not work, and I couldn’t get acceptable service from BangGood to fix it.

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
Mode 1
Mode 2
Mode 3

LED and Beam

Amutorch has chosen two options for this light.  And aspheric Nichia 219c, and what you see below; the Cree XP-G3.  Despite my best efforts, I received the XP-G3, an emitter I almost never like, over the Nichia 219c, an emitter I almost always do like.  ¯\_(ツ)_/¯


Tint vs BLF-348 (Killzone 219b version)


Random Comparisons and Competitive Options….


What I like

  • I do like the body except the mismatching head
  • I happen to like aspherics

What I don’t like

  • My biggest gripe with this light is that it doesn’t work (and that many users report that their copy does not work)
  • Replacement drivers are not available
  • Uses Cree XP-G3

Up Next

I haven’t really made my schedule for next week, so we’ll just have to see where the weekend takes me.  I have lights, chargers, cells, and other fun stuff in for review, so there’s plenty of work to do!

  1. Zeroair,
    I read your review of the Amutorch AT40. Too bad you received the wrong emitters and it didn’t work to boot.. I also received the wrong emitters from Amutorch. I requested the 2up XPL Hi option and received the 4up Nichia LEDs and an aspheric lens. Mine works just fine but I hate the aspheric. I’m still waiting for a reply from Neal at Nealsgadgets where I bought the light. My understanding is he is very slow to respond but eventually he does the right thing. However, it took seven weeks for my light to arrive. I suspect Neal has problems dealing with Amutorch.

    So, I have some questions for you:
    Have you made contact with anybody at Amutorch who does customer service?
    Would you be interested in trading heads?
    Would you be interested in selling your light or the head?

    I look forward to hearing from you and I’m enjoying your flashlight reviews.

    1. I’d be glad to send it, but I already sent it to another friend to see what he could do with it. Sorry!

      I haven’t contacted Amutorch about it, though.

      Thanks for reading! Sorry I couldn’t send the light to you!
