Sofirn dropped the SC31 Pro 18650 Andúril flashlight not long ago, and I finally got my hands on one.  It’s notable because it’s a very low-cost Andúril light!  Read on for some thoughts and testing.

Official Specs and Features

Here’s a link to the official product page.

Versions of the Sofirn SC31 Pro Flashlight

There’s just one body of the Sofirn SC31 Pro, but it’s available for purchase in two emitter temperatures:  6500K (seen here) and 5000K.

Price

Without a cell, this light clocks in at $28 (sale price).  Looks like it’s $31.99 right now on Amazon (referral link).  The Amazon price with the cell is $40.

Short Review

I’d consider this one a good beater light.  Inexpensive, Andúril user interface, lighted switch.  It’s a good light, especially for the price.

Sofirn SC31 Pro Flashlight Long Review

The Big Table

^ Measurement disclaimer:  Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.

What’s Included

• Sofirn SC31 Pro Flashlight
• Sofirn 3000mAh 18650 (button top, standard)
• Spare o-rings (2)
• Lanyard
• Charge cable (USB to USB-C)
• Manual

Package and Manual

I couldn’t find the manual anywhere else, so here’s a pretty solid copy of all the English pages.

Build Quality and Disassembly

The build quality of the Sofirn SC31 Pro is commensurate with the price.  It’s around a $30 light – seems about right.  That’s for simply build quality though.  The actual guts of this light (discussed later) put it in a separate (and higher) category.

The head has minimal cooling fins, and overall retains the “tube light” nature.

The body has ample knurling, and it’s sharpish.

Even the tailcap smartly has knurling too.  This makes it very easy to unscrew.

More on this clip later.

The threads on this light are very smooth.  They’re square-cut, sort of long, anodized, and again… very smooth.

The head end has a nice thick spring.

The tail end also has a nice spring.

And the cell tube removes fully too, so here’s a better shot of both springs.

The cell tube is removable fully, and also reversible.

I think this alignment of the switch LEDs is pretty normal… if you’re expecting them to be on… some… other axis, then this might not be the light for you.

Not sure whatever else you thought about those square anodized threads above, but the first thing I thought was “hey that’s like a new S2+ threading!”  I have only one new S2+, and it’s a copper one.  And yes it threads on perfectly.  And also YES it works fully!  Sort of a bonus is that you now also have a mechanical tailswitch!  (You’ll ask so:  No it doesn’t really work the other way.  Yes, it connects electrically BUT notice that you’ve taken out all the switches.  So no good way to modulate the modes.)

Size and Comps

Dimension: 117.5 mm (length) x 25.4mm (head diameter)
Weight: 59±1 gram (without batteries)

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).

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

A pocket clip comes already attached.  It’s the lowest kind of pocket clip (and leads heavily to my opinion of the build quality).  It’s a friction fit clip, and mine is bent all crooked.  I could fix it but really, let’s just get it right the first time!  This is not the biggest deal and doesn’t affect functionality.

As I said above, the clip only goes in one spot, but the cell tube is reversible, so the clip can end up on the head or tail end per your preference.

A lanyard is also included and attaches to the tailcap.

The light will also headstand, and there are no “reliefs” to let light out when doing so.

With the reversible cell tube, the light can technically reasonably be used as a hat light.

There is also a magnet tail cap option, but my package did not include that.

Power and Runtime

The SC31 Pro operates on a single lithium-ion cell.  I have a package that had a cell included.  It’s a 3000mAh button top and is a completely standard cell.

The cell goes into the light in the usual way – positive terminal toward the head.

Here are a couple of runtimes.  As with most Andúril lights I test, I set the light to the stepped modes, and test the two highest modes.  First is Turbo (that is, double click when the light is on).  The light reaches around 1800 lumens and steps down at ~30s pretty heavily.

Interestingly the Highest of the stepped modes also steps down pretty heavily, again to around 200 lumens.  I don’t observe low voltage protection when testing with the bench power, but I’m assured Andúril has it!

EDIT:  Many people have reminded me that often Andúril needs to be calibrated to allow the light to function properly.  I don’t disagree, but I also think the light should function correctly out of the box.  If it doesn’t, then this isn’t a light suited to beginners, or people unwilling to calibrate.  Calibration isn’t hard, but it’s very specific.

So I calibrated the light.  Here’s the graphic that should help with temperature calibration.

Start with the light off.
Click 3x – this puts you in battery check.  Feel free to confirm this by waiting for the battery check output.
Click 2x – this puts you in Sunset.
Click 2x – this puts you in Beacon.  I pause here to confirm I’m in beacon.
Click 2x – this puts you in the Temp check mode.

At this point wait and see what the calibration is.  The light will blink a number of times (the tens number), then blink a number of times to reveal the ones number of the thermal setting – in degrees Celsius.  For example, when I checked temperature calibration, the light blinked 4x, then paused, then blinked 1x.  But pay attention…. it could have also been 1 blink followed by 4 blinks.  Forty one, or onety four… no… 41°C or 14°C.  The latter is more reasonable, so let’s assume it’s 14°C.  Even at 14, that’s too low for my room temp, so I’ll need to calibrate the light.

What does that mean though?  It means that the light thinks my room temperature is 14°C or 41°C.  That’s far (or very far) off – my room temperature is around 22°C.  It also means that there’s only a tiny window of operation before the light hits the thermal ceiling as programmed (probably 50°C but I’m not sure).

This light definitely needs thermal recalibration.  I set the room temperature to [accurate] – 22°C.  Then I set the temperature limit to around 55°C.  That means there’s a broad range of operating temperatures for the light to work – from room temp 22°C, all the way to 55°C.

Once you’re in temperature check (covered above), do the following:

Click 4x.  The light will blink 1x and then blink very quickly as an indicating it is willing to accept your input.  You can do nothing (aka “wait”) or click the number of times of degrees C of your room – 1 degree per click.  This means that while the light is blinking for my input, I clicked 22x.  Now the light knows that this temperature is 22°C.  Important!
Click 4x.  The light will blink 2x and then blink very quickly as an indicating it is willing to accept your input.  You can do nothing (aka “wait”) or click the number of times you wish for the thermal ceiling minus 30.  For example, if you wish to set the ceiling to 55°C (as I did), then you click 55-30, or 25x.  Now thermal calibration is complete.

After doing all this, I reran two output tests, which can be seen below.

Charging

The SC31 Pro also has built-in charging, by way of a USB-C port in the head.  The charge port cover is thick and fits in very firmly, and is quite nice.

An appropriate cable is included.  USB to USB-C.

Charging is a respectable ~2A, and, and takes just over 2 hours.

Modes and Currents

Pulse Width Modulation

Andúril lights (that aren’t the linear drive as the Emisar D4V2  with E21A is) have PWM, we know this.  It’s not bad enough that I notice it though (surprisingly; it’s pretty slow on low!)

You’ll note 9 test modes below (while there are only 7 stepped modes).  Since the ramped low is much lower than the stepped mode’s low, I’ve included it.  The right-most is the “double click turbo.”

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, which is 50 microseconds (50us). 10ms.  5ms.  2ms.  1ms.  0.5ms.  0.2ms.  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

A single switch controls the SC31 Pro.  This switch is an indicating e-switch and bigger than is typical on this type of light.  It’s also very textured, and quite easy to differentiate from the charge port cover (which is on the opposite side of the head.)

This light ships with Andúril by ToyKeeper.  Andúril is a fantastic UI, and extremely versatile!  The product page even specifies the Andúril version:  2020-03-18.  That’s pretty good attention to detail!

The switch has brightness settings, and can also do some “breathing” type features.  It does seem to be green only, so the Andúril features used to change the switch color don’t do anything here.

First off, here’s the UI chart made by ToyKeeper.

Here’s my UI table!  This table doesn’t cover the aux and switch LEDs, but they’re somewhat configurable too.

LED and Beam

The emitter used here is a Luminus SST-40, and my sample is 6500K temperature.  There’s also a 5000K version, which I recommend you buy unless you hate everything about life.

The reflector used is a smooth, moderate depth reflector.

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

I normally test only in stepped mode.  However, the ramped output offers a much lower low, so the first mode below is actually the lowest of the ramped.  Then the next 7 modes are the stepped options, and the rightmost is the [double click to] Turbo.

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.  As stated above: I normally test only in stepped mode.  However, the ramped output offers a much lower low, so the first mode below is actually the lowest of the ramped.  Then the next 7 modes are the stepped options, and the rightmost is the [double click to] Turbo.

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