Skilhunt M150v3 Flashlight Review

Skilhunt M150v3 Flashlight Review

Skilhunt has updated the M150 flashlight to the M150v3 edition! This one features a great user interface and has a high CRI Nichia 519a.

Official Specs and Features

Here’s a link to the Skilhunt M150v3 flashlight product page.


Of course, this is v3, so there are previous versions. I’ve tested one before (Skilhunt M150). Currently available are three emitters; cool white, Nichia 519A, and Samsung LH351d.

There are also two body colors: black (seen here) and grey.


This specific version of the Skilhunt M150v3 flashlight is $44.90. Other emitter versions vary in price a bit.

Short Review

I love the other M150 I have. The only way I could probably love it more is if it had a better emitter. And the M150v3 does!! This Nichia 519a emitter is just fantastic. I like the user interface too – it’s very similar to what’s on the EC300 (which I also love!)

^ 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.

Build Quality and Disassembly

Skilhunt M150v3 flashlight

Skilhunts are usually well-built lights, and this one is no exception.

The threads are square-cut and lubed an appropriate amount. That spring is also removable so that the magnet can be removed, too.

Inside the cell tube is a sticker indicating that the cell should go with the positive end toward the head.

The head end doesn’t have a spring; just a brass button.

The tailcap has a ring to allow a lanyard attachment and also room for the magnet.

Size and Comps

Length 84.0mm
Head diameter 21.0mm
Body diameter 18.0mm
Weight: 34 g (without battery)

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 pretty nice clip and updated from my previous version of the M150. This is a marked upgrade from the other version

Also included is a lanyard, which attaches either through the pocket clip (less recommended) or the tailcap, where there are two holes for this express purpose.

The tailcap has a magnet, too, which is plenty strong to hold the light. As stated above, this magnet is removable.

Power and Runtime

The M150 runs on a single li-ion cell.  It uses a 14500 cell, and Skilhunt includes an 800mAh version.

That cell is a button top, but any type cell that fits should work fine – the positive end doesn’t have any physical protection that will prevent it. Any type cell you use goes in with the positive end toward the head.

The M150 also operates on a 1.5V AA-sized cell such as NiMH or Alkaline.  The output with these will be greatly reduced, but every mode is available.

Using a 14500 cell, the light exhibits LVP, shutting off around 3V.  Output steps down along the way, but the output is very flat.

You may note that these outputs (nearly all of them) are much lower than what is written in the manual. I wonder if that specification is for some other non-Nichia-519a emitter. I don’t have a way to know that though.  I will say, though, that these outputs are “just fine.” I don’t need 2000 lumens (or 750 as stated in the manual) out of a little light like this. I’d much rather have steady output for longer (and this one has that!!)

The light also has built-in charging.  There’s a connector opposite the switch.  One end is a USB plug, and the other is a proprietary magnetic connector.

The connection works well.

Charging on a 14500 cell commences at around 0.9A, which is plenty fast for an 800mAh 14500 cell.  Charging looks very good.

Modes and Currents

14500 first:

Pulse Width Modulation

No PWM at all.

14500 is in the top row and AA is in the second row.

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

There’s a single switch on the M150v.  It’s a side e-switch, with an indicator in the center.  It’s a big secure switch, with a very positive but quiet click.  I very much like this switch. The switch seems unchanged from the previous iterations.

The cutout for the switch in the head is the same size as the charge connector, and while it’s hard to distinguish between the two while holding the light, I found that it didn’t matter; I’ll just pinch the light with both spots between my fingers, and activate the light.

The user interface could be a bit daunting, but it’s very straightforward when you get used to it. It’s also very logical and provides access to low from off, which is as close to a requirement from a user interface as I have.

Here’s a UI table!

State Action Result
Off Hold Low (Memory between L1 and L2)
L1 or L2 Hold Iterate between L1 and L2
L1 or L2 Click 2x No change in level
Off Click 4x Lockout (Three blinks of main emitters to confirm)
Lockout Click 4x Unlock to Low group (memory, can be L1/L2)
Lockout Click 2x Iterate lockout indicator^
Lockout Hold Momentary Output (Appears to be approximately L1)
L1/L2 Click Off
Off Click On in “Main Group” (Mode memory M2/M1/H)
Main Group Hold Mode advance (M2 > M1 > H)
Main Group Click Off
Main Group or Off Click 2x Turbo Group (Mode memory T1/T2)
T1/T2 Hold Iterate between T1 (higher) and T2 (lower) output
T1/T2 Click Off
T1/T2 Click 2x Main Group (memory output)
Main Group or Off Click 3x Strobe Group (with memory)
Strobe Group Click 3x Previous Group (T1/T2 or M2/M1/H, depending on how you accessed Strobe Group)^^
Strobe Group Click 2x^^^ Strobe Advance (S1 > S2 > S3)†
Strobe Group Hold No result

^ Lockout indicator blinks a red switch every 2-3 seconds.
^^ Aside from just general mode memory (which you know I don’t like) this seems to me to be the only place where you may need to immediately remember what mode you were in so you have the experience you expect. However, the difference is getting the two highest white outputs, or the three main white outputs – it won’t be that dramatic even if you don’t remember. Also note that if you access the strobe group from off, triple-clicking will not return to off. For continuity, it should! In fact, if you accessed the strobe from an off state, a triple-click sends the light to the Main group!
^^^ Seems like the strobe group is the only group that isn’t advanced by a hold. Since there’s no hold anywhere else into or out of Strobe, I am not sure why that user interface continuity wasn’t maintained here.
† Strobes are like this:

S1: Disorienting strobe of White (turbo, ish)
S2: SOS (main white, some mid-High output)
S4: Beacon (one highish blink every second or so)

LED and Beam

The emitter of choice here is a Nichia 519a and offers High CRI.

That’s of course a fantastic choice, and everything about this light’s output is great because of it.

LED Color Report (CRI and CCT)

Check out those circles – the red and black circles. Black is “perfect” or “ideal” and the closer the red (test light) circle comes to the black, the better! This one is one of the best. Great CCT (around 4200K) and very high CRI, at around 97. 14500 first, then AA.


These beamshots are always with the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure. 14500 first, then AA.

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. 14500 first, then AA.

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



What I like

  • Complete package
  • Runs on both 1.5V cells, and 3.7V (lithium-ion) cells
  • This new Skilhunt UI has something for everyone (and I like the UI)
  • The button is perfectly clicky and ‘pinch to click’ opposite the charge port works nicely too
  • Nice charging built-in
  • Updated pocket clip is fantastic

What I don’t like

  • The output is way below the specification in the manual (I wonder if the manual is written for another emitter?)
  • Charging requires a proprietary charger cable

  1. It appears that manufacturers are getting away from those incredible huge lumen counts. The turbo mode on those inflated lumen flashlights are useless so why do they even have a turbo mode?
