Amutorch E3H Flashlight Review

Amutorch E3H Flashlight Review

Another Amutorch in my hands – this time it’s the Amutorch E3H flashlight.  This light claims 3000 lumens and uses Cree XP-L HI emitters. Read on!


Official Specs and Features

Here’s a link to the Amutorch E3H flashlight product page.

Versions

There’s just one Amutorch E3H flashlight.  But in general, there are quite a few versions of the E3 series.  Even the E4 could be reasonably considered part of this series.  For example, the E3S and E3 are similar, and the E3Q is even more similar.

Price

As seen in this review, the price is $62.45.  This includes the 21700 cell and a 2-bay charger.


Short Review of the Amutorch E3H Flashlight

As far as 21700 EDC-type lights go, this one is fairly slim.  I appreciate that.  I do wish a 5000K  or 4000K Cree XP-L HI was offered, as 6500K is too cool.  Also, there’s no pocket clip!  That’s a downside for me personally.  There are two more things I don’t care for.  The first is the dramatic timed stepdown, and the bad mode spacing.  It sounds like I don’t like the E3H, but as a host, it’s quite nice!

What’s Included

what's included

  • Amutorch E3H Flashlight
  • Amutorch 5000mAh 21700 (with kit)
  • Lanyard
  • Spare o-ring
  • Charger (with kit)
  • Charger cable (USB to USB-C) (with kit)

Package and Manual

The box is unlabeled – no “E3H” anywhere on here that I can find.

One thing that annoyed me about these Amutorches is this sticker, seen below.

made in china sticker

Now, I don’t mind what the sticker says at all – I get it.  National pride for build or whatever (or maybe it’s a law?)

What bothers me is that this sticker doesn’t remove cleanly without very deliberate effort.

The residue does wipe off cleanly, though.

There is no manual.

Build Quality and Disassembly

feature photo

Overall the build quality here is fairly good.  The light feels great in hand, for whatever that’s worth.  The anodizing isn’t quite typical – there’s just a bit of texture to it somehow.

Aside from the nub on the lanyard loop (which rotates freely), there isn’t any “sidedness” to the light.  The sides are all the same except for the printing on the bezel.  The bezel feels like stainless steel.

Here’s the top-down view!

 

You’ll need to remove the tailcap for cell swaps, and the ribs here help with that.  Despite having an “anodized thread” sound, they’re very easy to use.

tailcap

Again, I’m pretty sure this bezel is stainless.  It’s flush; no flutes or anything.

head and cooling fins

As you can see, the head has quite a bit of cooling fins, though they’re only moderate depth.

The texture in the anodizing is fine and actually great, except when it comes to the threads.  They’re just a bit rough, but not in a way that makes them feel untrustworthy.

tailcap threads

Inside these parts are springs – a real spring on the tail end, and a faux spring on the head.  While this is fine, I think many or most companies would use a brass button here.  But these faux springs seem to be Amutorch’s thing.  Anyway, it works fine, and as I said above – you should be buying the “with cell” package anyway, so you shouldn’t be needing a spring here for shorter cell support.

Size and Comps

Dimensions: 106mm long x 28mm head diameter x 25.4mm body diameter
Weight: 73g

If the flashlight will headstand, I’ll show it here (usually the third photo).  If the flashlight will tailstand, I’ll show that here, too (usually the fourth photo).

in hand

Here’s the test light with the venerable Convoy S2+.  Mine’s a custom “baked” edition Nichia 219b triple.  A very nice 18650 light.

And here’s the light beside my custom engraved TorchLAB BOSS 35, an 18350 light.  I reviewed the aluminum version of that light in both 35 and 70 formats.

Retention and Carry

The only thing included for carry of the Amutorch E3H flashlight is the lanyard, which attaches only on this freely-rotating lanyard loop on the tail end.

lanyard ring

Even with the tailcap fully tightened, this ring rotates easily.  That’s either good or bad, depending – but since there’s no other landmark on the body, there really doesn’t seem to be anything bad about the lanyard rotating freely.  It’s not going to catch on a pocket clip, or whatever, for example.

lanyard ring detail

The downside of that, of course, is that there is no pocket clip.  Also no pocket clip option, and really nowhere to even attach an aftermarket pocket clip.  It’s a lanyard or nothing.

Power and Runtime

Amutorch provides in the kit what you’ll need for powering the Amutorch E3H flashlight.  It’s a lithium-ion cell, size 21700.

included 21700 cell

This is a standard flat-top 21700 cell.

The cell goes into the light in the usual orientation – positive end toward the head.

Here are a couple of runtime graphs.  Amutorch states the turbo output to have a 30-second duration, so we’ll call it a “timed stepdown.”  But in my test, this high output didn’t last 30 seconds.  As a result, I read this as a “507 lumen light” on Turbo, despite the initial output being nearly 2500 lumens.  2500 lumens is around 83% of the claim.

runtime graph with included 21700 cell

In the graph above, I did reset the light to turbo a couple of times.  You can see toward the end of all these runs that the main emitters are flashing a low voltage warning before finally shutting off, too.

runtime graph with included 21700 cell

One of the things I like very little about this light is the mode spacing.  I immediately set my light to Group 5, which has 4 modes (plus turbo) and I have to say there’s really no reason to do so.  High and Medium are so close in output that it’s hard to even tell them apart.  These runtimes look good though, with flat output for the duration.

Charging

Included with the package (if you buy the package) is this 2-bay charger.

2-bay charger

This is just a random thought about the charger, but I really like the desk presence of this charger.  It sits very comfortably, and just overall seems nice.  And it’s USB-C!

2-bay charger USB-c

There’s a very clever bit of branding here, too – the owl logo of Amutorch…. see those white blobs beside the logo?  Those are the charge indicators!  So when the bays are filled (and the device is plugged in), they’re either red (charging) or green (charged).  Pretty clever.

This charger is only for lithium-ion cells – no NiMH, for example.  That’s a bit of a downer.

2-bay charger

Amutorch includes a charge cable with the kit – USB to USB-C.

Charging is certainly slower than the 5000mAh 21700 cell can handle, but overall 1A is not too bad of a generic charge current.  I will say that the “CV” phase of this charge cycle just goes on and on and on – In the graph below you can see at around 5 hours, the charge current is around 0.05A or whatever – at this point, the cell is almost certainly “nearly full” or even “full enough.”  Maybe hovering around 4.18V or whatever.  The additional time might add additional mAh.

charge graph

The charger does work C to C, but it’s still 5V input.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
Turbo 3000/700 30s/180m 507 6.20
High 700 3h30m 554 1.40

Low 150 ? 140 0.33
No name? Eco?  Moonlight? 30 100h 20 0.05

Pulse Width Modulation

No PWM on any mode.

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.  Also, here’s the light with the worst PWM I could find.  I’m adding multiple timescales, so it’ll be easier to compare to the test light.  Unfortunately, the PWM on this light is so bad that it doesn’t even work with my normal scale, with is 50 microseconds (50us).  10ms5ms2ms1ms0.5ms0.2ms.  In a display faster than 0.2ms or so, the on/off cycle is more than one screen, so it’d just (very incorrectly) look like a flat line.  I wrote more about this Ultrafire WF-602C flashlight and explained a little about PWM too.

User Interface and Operation

The Amutorch E3H flashlight uses a mechanical tail switch.  In this case, it’s a reverse clicky.  The switch is very clicky, with positive action.

reverse clicky switch

There’s an unusual delay between the switch being fully clicked and actuation.  The switch seems to need to be fully in its rest state before the action happens.  That’s unusual in that you’re probably accustomed to being able to keep on the switch just a little while switching modes or whatever.  Not so, here.

Here’s a UI table!  Spoiler, this is just like Amutorch E4 Brass I reviewed recently.

State Action Result
Off Click On (Mode Memory)
On Click Off
On Tap Mode Advance
On Tap 5x Group select (light blinks 1x, then 2x, 3x, 4x, 5x – click after the desired group)τ
On Double Tap Turbo
On Tap 3x Strobe
Strobe Tap Previous mode

τ The groups are as follows:
Group 1: 700lm
Group 2: 30lm-700lm
Group 3: 350lm-850lm
Group 4: 30lm-350lm-700lm
Group 5: 30lm-150lm-350lm-700lm

LED and Beam

Amutorch put three Cree XP-L HI emitters in the E3H flashlight.  This is a triple emitter light, and has an optic.

emitters

I don’t think Amutorch has stated it anywhere, but this looks to me to be the “narrow” version of a Carclo optic.  That suits me very well.

emitters

There are no flutes or features on the bezel, so no light escapes when headstanding.

These beamshots are always with the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure.

Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)

I keep the test flashlight on the left, and the BLF-348 reference flashlight on the right.

I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!

Conclusion

What I like

  • Nice build size and shape
  • Complete package
  • Neat little USB-C charger (with the kit)

What I don’t like

  • 6500K (and no warmer option is available)
  • Reverse clicky seems to be a bit…. slow.
  • Mode spacing is not ideal in the least.  I need a 1000 lumen high on this light.
  • No pocket clip!
