Thrunite W1 Blue “Aquachigger” Flashlight Review

Thrunite W1 Blue “Aquachigger” Flashlight Review

Thrunite has released the W1 Blue Aquachigger flashlight, a 16340 based flashlight.  This light has SST-20 emitter and an indicating e-switch.

Official Specs and Features

Here’s a link to the Thrunite W1 Blue Aquachigger Flashlight product page.  It seems they’ve changed the link and now it’s going to redirect to a package page with the orange H01.


Thrunite’s site right now seems to be a bit of a mess, but there are at least a few versions of the W1.  There’s this Aquachigger.  There’s the green Black Scout Survival version.  That seems to be all that’s listed.  All the versions are cool white.

If you want black, you could get the Wowtac version, which I have reviewed.


There doesn’t seem to be a price for just the Thrunite W1 Blue Aquachigger flashlight.  It’s now a combo, and alongside the Joe Robinet orange H01, the set is $29.99.  You can find that set here.

Short Review

This is a nice little light.  I do wish that Thrunite had gone with a neutral white emitter here. But I do think swapping will be easy.  All in all though, for the combo price, I think this is hard to beat.

Package and Manual


Build Quality and Disassembly

If you’re paying attention until now, you’ll note that there’s a Wowtac precursor to the W1.  I reviewed it, and I like it.  The Thrunite W1 Blue Aquachigger flashlight has the same feature set, but a redesigned body.

On the Thrunite version, we see rings instead of knurling, but otherwise, not many changes.

Here’s a top-down view.

“Chigg’s Army” this says.  Aquachigger is a youtube channel dedicated to hunting things in the water. Here’s a link to the youtube channel if you want to check out more.

On the tailcap is a logo of Aquachigger.

Inside the head here you can see that little has changed from the Wowtac version.  By “little” I mean “nothing.”  Not that that’s a bad thing.

The tailend has a spring.  But the head is just this brass button.

Size and Comps

68mm x 24.5mm x 20mm, and 40g without the cell.

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 main carry method will be the pocket clip, which attaches only to the tail end of the light.  The clip is a 2-way friction fit clip.  Two-way clips aren’t my favorite clips, to be honest, but on lights with only one attachment point, this does give the option of bezel up or down carry.

beside pocket clip

There’s a wrong way to install the clip – if you don’t press it fully into the groove, it’ll be out as seen below.

A magnet in the tailcap is plenty strong to hold the light.

There’s also a lanyard loop in the tail end.  No lanyard is included.

With the retention feature set, the Thrunite W1 Blue Aquachigger flashlight should serve just fine as a hatlight.

Power and Runtime

The W1 is powered by a single lithium-ion cell – in this case, a 16340.  An appropriate cell is included – a 650mAh button top.

The cell is installed into the light in the usual way – positive end toward the head.

Runtimes follow.  Turbo steps down fairly quickly, but not in such a way that it seems to be gaming the ANSI standard.  This is acceptable.  Also this is exactly the same performance as the Wowtac.

The light has an indicating switch, and when the cell voltage is low, this switch will turn red, then blink red.


The Thrunite W1 Blue Aquachigger flashlight also has built-in charging by way of a micro-USB port on the head.

An appropriate cable is included – USB to micro-USB.

Charging proceeds at around 0.5A, which is good.  That’s just under 1C for this 16340.  This requires around 2 hours for complete charging, and only charges to around 4.15 consistently.  However, when “topping” this cell up to 4.20V, there’s really negligible energy added (something like 3mAh), so I wouldn’t get too bent up about this being below 4.2V.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
Turbo 693/231 75s/74m 714 1.98
High 215 90m 223 0.58
Medium 58 5h 62 0.14
Low 7.5 60h ~ 0.01
Firefly 0.5 13d ~ 1mA

Pulse Width Modulation

Low and Turbo don’t have PWM, but the middle three modes do.  I don’t notice it, though.

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

There’s a single switch on the Thrunite W1 Blue Aquachigger flashlight.  It’s an indicating e-switch, with a gray translucent cover.

Here’s a UI table!

State Action Result
Off Click On (memory, LMH only)
Off Hold Firefly
Firefly Hold Lock
Lock Hold Unlock
Any Double Click Turbo
Any Triple Click Strobe
On Click Off
On Hold Mode cycle (LMH only)
On for some time (“a while”, 30ish seconds) Hold Low

That’s a similar UI to other Wowtacs (A4, A5, and A6 for example) and also many Thrunites (TC20 for example), except for access to strobe.  I love that fact mainly because I like the UI in general – very simple but enough features, and easy to access low and high.

LED and Beam

Unlike the Wowtac W1, the Thrunite W1 utilizes a Luminus SST-20 emitter.  It’s cool white, too, and despite there being text of “neutral white” on the website, Thrunite seems to be slowly creeping away from any NW offerings at all.


This light has a shallow orange peel reflector but provides a nice tight hotspot.

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

Tint vs BLF-348 ( 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 219b BLF-348 because it’s inexpensive and has the best tint!


What I like

  • Meets (really “exceeds”) specifications on throw and output
  • Complete package
  • Included cell is good
  • Nice hotspot
  • Magnet is nice and strong

What I don’t like

  • Cool white emitter
  • PWM on middle three modes
  • There doesn’t seem to be a “nonbranded” version (and none of these branded versions are orange.)
