Mateminco X6S Flashlight Review

Mateminco X6S Flashlight Review

The Mateminco X6S isn’t really a new flashlight but it’s worth having a look for a nicely built host! These emitters are great, too! Read on!

Official Specs and Features

Here’s an affiliate link to the Mateminco X6S flashlight product page.


I’ll say there’s just one “version” of the Mateminco X6S flashlight but it’s a little more nuanced than that. At least three emitter options are available – Cree XP-L HI in two CCTs and a Nichia 219c version (seen here). If you opt for the Nichia 219c version, you’ll get a dimpled optic, which will probably provide a more floody beam. The package includes both the bodies that you’ll see here later.


The price for the Mateminco X6S flashlight is $35.95. That’s an affiliate link to NealsGadgets.

Short Review

Neal of Neals Gadgets was getting a package together to send and I mentioned this Mateminco X6S flashlight. As you probably guessed, it’s not one of his newer lights. I said oh well, drop it in the package and we’ll have a look! Maybe someone can use it as a host or something. And I think you’ll like it for that!!

^ 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

Mateminco X6S flashlight what's included

  • Mateminco X6S flashlight
  • Two cell tubes (18650 and 18350)
  • Lanyard
  • Pocket clip
  • Spare switch cover (3, various colors)
  • Spare o-rings (2)

Package and Manual

My box was actually labeled incorrectly – I received the Nichia 219c version, and not the Cree XP-L HI 3B as shown on the box below.

That’s actually fine, because these Nichia 219c’s ended up being very great!

There is no manual.

Build Quality and Disassembly

The Mateminco X6S flashlight build quality is great! This feels a lot like Convoy flashlights, to be honest, and that’s not a bad thing. For $36, that seems about right. Mateminco is a nice brand on its own though, and shares build quality levels (and providence, probably) with Astrolux.

It’s nice that you get both cell tubes for the Mateminco X6S flashlight. This makes for a fun setup!

The head has some nice and fairly deep cooling fins. As you can see, the bezel has knurling, too.

Both head and tail have beefy springs, allowing just about any type of (appropriate) cell to fit fine. The parts are also very accessible. If you need to tear the light down and change something, it’s very easy to do so.

Size and Comps

129.6mm x 40mm(18650); 123g
92mm x 40mm(18350); 111g

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.

Also above is 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 is included.

It’s a fairly standard friction-fit pocket clip, but on the cheaper side of things. It fits only the 18650 tube.

Next up is the lanard. This attaches only on the tailcap and only one side of the tailcap has lanyard holes.

Since there are two holes (on one side), the lanyard can be installed and not interfere with tailstanding. This is the way!

Power and Runtime

A single lithium-ion is used for powering the Mateminco X6S flashlight. If you’re using the long tube, that lithium-ion is an  18650. If you’re using the short tube, that lithium-ion is an 18350.

Here are a few runtime tests of the highest three modes. I tested only with an 18650; the only difference you should see with a 18350 is shorter runtimes if you’re using a very high-quality 18350. This light is capable of drawing nearly 12A on the highest output, so whatever cell and size you use will need to be very high quality.

It wouldn’t be unreasonable to call this performance disappointing. That’s why I consider this light mostly a host, in need of a new driver (if nothing else).

Low voltage protection is questionable – the light steps down but does seem to stay on for a while and past what’s a good shutoff voltage. If you use this as a host, swapping drivers wouldn’t be a terrible idea!

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
9 (100%) – (3000 for cool white) 1712 (0s)
1275 (30s)
8 910 5.29
7 598 2.44
6 322 1.19
5 160 0.73
4 38 0.25
3 13 0.09
2 2.5 0.02
Moonlight 0.3 0.01

Pulse Width Modulation

All the modes except 100% use PWM. This PWM is no slower than what we see on something like Andúril, so it’s fast enough to not really be a problem.

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). 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

A single switch controls the Mateminco X6S flashlight. It has a neat blue backlit feature. This is a reverse mechanical clicky switch, so mode changes, while the light is on, will work fine.

The switch is fairly bright and looks great! When the light is turned on, the switch LEDs will always turn off.

The user interface is Bistro, by ToyKeeper. I’ve had some form of Bistro a number of times throughout the years, most notably in the FidgetHQ Aonic (for example).

Here’s the Bistro UI chart by ToyKeeper. This is a comprehensive graphic, of course.Mateminco X6S flashlight bistro user interface

Some of what I’ve said before regards the BLF A6 user interface, but there’s a lot of overlap.

Here’s basically the most useful way to visualize the UI. Bistro is a fantastic UI, with plenty of options. In particular, I like the option to turn off Mode Memory. (The light ships with memory on). Another thing I love is that the light has a battery check option. Here’s the detail on what you see when you use batt check.

0 blinks: < 1% full (< 3.0V)
1 blink : 1% to 25% full (3.0V to 3.5V)
2 blinks: 25% to 50% full (3.5V to 3.8V)
3 blinks: 50% to 75% full (3.8V to 4.0V)
4 blinks: 75% to 100% full (4.0V to 4.2V)
5 blinks: > 100% full (> 4.2V)

Another thing I absolutely love about this UI is the ability to go backward in the modes.  Often I am in a mode and I think “Is this enough light?” and progress to the next mode.  The next mode is too much so I might have to cycle through to get to the previous mode.  Not with this user interface!  Just “medium press” (time, not pressure) to go back a mode.

LED and Beam

My version of the X6S has three Nichia 219c emitters (despite what the box says!). I haven’t always been the biggest fan of 219c (with 219b being legendary, of course), but these are great!! The Mateminco X6S flashlight is a triple, but not a “standard YAT triple.” The emitters are spaced apart. Most importantly, this means the head is bigger, with bigger mass, so should be able to deal with heat better.

LED Color Report (CRI and CCT)

These Nichia 219c emitters come in at around 5000K and hold very steady even on the higher current output levels. (Often emitters will go toward the blue/higher CCT as they’re driven harder.) These stay at around 5000K throughout the levels and are high CRI!


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

  • Great CRI from the Nichia 219c emitters
  • Good build quality
  • Nice package that includes 18650 and 18350 tubes
  • Big head that should deal with heat well
  • Lighted switch is a neat touch
  • The ability to go backward through the output levels
  • Programmable driver
  • Very easy to take apart and modify

What I don’t like

  • Stock driver doesn’t seem to have low voltage protection
  • PWM on all but the highest output (but it’s fast, so “eh” to complaining about this)
  • Box is mislabeled. Confirm with Neal which emitters you’re getting (if it matters to you)

  1. You received the 219C version, NOT XPL-HI! If the CRI doesn’t give it away, you can see the black and white boundary characteristic of 219C emitters in the pictures in the “LED and Beam” section.

    1. Whew that’s a good catch right there! I’ve updated the text. I read it on the (mislabeled) box and didn’t ever think much about it again. But you’re right, the high CRI should have caused bells to go off!
