MecArmy PT16 v2 Review

MecArmy is a new brand that has released a couple interesting products like the SNG3 and this PT16. I know there are lots of speculations for this light since just a handful of people have one, maybe because this is not exactly a budget light and numerous time it has been asked why MecArmy lights are so expensive. I never paid too much attention to the PT16 until Dale mentioned in a comment that he has one and made over 1,000 lumens, and without thinking it twice I placed my order. Smile

I got mine from Goinggear for $58 using “ggcpf10” coupon (-10%) and it was actually cheaper than buying from GB, also this is the second release of the PT16, I believe the only change vs the first is the UI. Today it arrived and I decided to write a review. It wasn’t my plan as I was just going to take some pictures and amp measurements, but then I realized this light really deserves a review.

.
.

Specifications from manufacturer:
LED:3 CREE XP-G2
Max Output:1000 lumens (underrated!)
Max Run Time:20 h (more like 16 hours max)
Max Beam Distance:140m (really?)
Battery:16340 lithum ion
Length:67mm/2.638in
Head Size:28.8mm/1.134in
Weight:40g/1.411oz (actually heavier)

.
.

Packaging & contents:
Inside the retail box with a peek flap there are: PT16, no-name 16340, 3 o-rings, instruction manual and lanyard.

.
.

Build quality, size and weight:
Overall machining quality and anodizing are very very nice. There are zero rough edges or imperfection in the machining, threads are thick and square, the front bezel has perfect fit and the button has just the right size. Whichever factory that makes these lights definitely know what they’re doing!

The tail reminds me of the “Moodoolar triad tailcap”, not only by the looks, but also the price. Silly

The parts… The body can be locked out at both ends.

ALTUN” marking on the back of the driver. It does seem like a well made driver, with some contact points probably for FW reflash. The positive contact on the body is spring loaded and the charging circuity is covered by a plastic disk.

Close up of the threads, with double o-ring in the back. The body is 2.3mm thick.

Front close up, this is NOT a carclo 20mm triple optic. It measures 22.7mm and the optics don’t touch each other.

Size comparison with my other lights this size. The PT16 is one of the heaviest, doubling the weight of the Fenix E15.
16340, CooYoo Quantum, Lummi RAW, S1 Cu, E15 2016, PT16, MaratacAAA Cu, D25C, Sinner 18350

The PT16 is also the chubbiest.

.
.

UI & integrated charging:
For this version the UI has been upgraded, and it is pretty good with instant access to low, turbo and strobe from OFF.

From OFF:
-Click for low
-Double click for turbo
-Triple click for strobe
-Hold for momentary turbo

From ON:
-Click for OFF
-Hold to change modes

The microUSB connector is in the body like the cooyoo/illuminex. Red and green LED shows charge status. Integrated charging comes handy for some people, but for me it is pretty much useless. I would rather have a even more compact and lighter flashlight.

Charge test with Efest 16340 at 2.5V:
-Time: 1hr32min
-Maximum rate: 5.1V 0.56A
-Capacity 0.71A
-Termination voltage: 4.22V at green led, 4.19V after 5 minutes rest.
-Current draw after charge completion: 4mA
The body got pretty warm during the charge process.

.
.

Performance:
This might be the most interesting part…

Current reading
Low: 0.04A
Mid: 0.17A
High: 0.68A
Turbo: 3.27A with efest 16340, 2.95A with included 16340.

Beamshots:
Low

Mid

High

Turbo

.
.

Vs other lights:
Manual mode, 1/125 left, 1/1600 right. F4.0 fixed ISO and WB.

PT16 vs Fenix E15 2016:

PT16 vs Olight S1

PT16 vs Sinner 18350, 3x XPG S2 0D with 3A Qlite and narrow frosted optic

PT16 vs Modded D25C, XPL HI V2 1A and FET driver (5.3A)

.
.

Ceiling bounce test: Panda bear used to show tint and hold the meter Smile These are just my ceiling bounce numbers, they have nothing to do with real lumens. But they do give you an idea of what level of output you get.
Manual mode, 1/10 F4.0 ISO200 fixed WB

PT16…Starts at 175.2 but after 30 seconds it drops to 152.3

Fenix E15 2016… 87.2

Olight S1… 89.4

Maratac AAA with 10440… 51.9

D25C…170.1 This is a 1,300lm+ light, but it shows a lower value because flood lights do better in my ceiling tests.

Sinner 18350 triple XP-G… 150.1

.
.

Runtime and temperature regulation:
I usually don’t even bother with the manual, but this time it said something that caught my attention: “turbo will drop to 70% of maximum brightess after 3 minutes…output will also be adjusted by real time temperature monitoring” is this some kind of PID? Temperature regulation in a light with such short runtime? Lets find out.

This one was performed with fan cooling, I will do one without any cooling. It does seem like temperature regulation to me, but the 16340 has so little capacity the output starts to drop due to low voltage when the temperature starts to normalize. With a higher capacity cell we can observe the temperature regulation more evidently.

1hr 30min after the runtime test finalized it was still lit and putting out some useful light, it wasn’t much, but I’d say at least 5 lumens. At this point I took the battery out and it read 2.54V. This light does not have low voltage cut out. But then this also means it is compatible with CR123s.

.
.

Veredict:
This is a FUN light! Just take it out anywhere and blast the 1,000 lumens from a tiny flashlight, even strobe if you wish. I’ll be keeping mine in the keychain, but it won’t last very long though because it just adds so much weight and volume, it makes an uncomfortable bulge in my jeans pocket. In the end I might just go back to the E15, but I really much prefer the UI and output of the PT16.

My new keychain setup, these are my EDC items.

It is a bit expensive, but in my opinion it is well worth the price. The PT16 is very unique, I believe this is the first 1,000lm 16340 triple. Other manufacturers should look at this light and learn, it’s not like they can’t make a PT16 competitor, they just don’t want to. All I see is the same mediocre performance being released over and over, ~500lm flashlights are a thing of the past. S1, E15, RS16, D25C, you name it. How hard is to put a XPL or XML and drive it at 3A? We’ve been doing this ourselves for years. Nitecore EC11 seems to be the exception.

Soon I will update my review with a charge graph and runtime graph at various output levels, but for now this review is done. I hope you have enjoyed it.

Yea, I don’t know. Shiny body flashlights meh, seen enough of them. 1000 lumens seen enough of those too. I don’t know why flashlight makers can’t just stick with the awesome Convoy black matte finish, it really is the most awesome. Along with the knurling. Know the triple is nice to see, they make great flooders. The programability of it I will have to inspect for myself to see if it is of any use.

Oh, yes great review btw, cheers…

It is cute, it looks like something a Godmes would poop out. ha ha hah ah ha.

I also have the PT16. The body isn’t shiny. It’s not like the cheap super-shiny anodizing on a Sipik 68. It’s actually a very nice Type III anodize and looks virtually the same as the matte black on my Convoys and BLF A6.

How low is low? Would you call it moonlight/firefly low (~1 lumen)?

Thanks everyone, I just read the manual and it mentions variable output by real time temperature monitoring, if it really has PID regulation this is a big deal, I will test it tonight. What I do know for sure is that the output starts dropping almost immediately after turn on.

The manual says 5lm but at 40mA it should be about 15-20lm. Looks almost the same as bright as the Nitecore tube. But it’s low enough for most tasks, and has decent runtime with a 16340, about 16 hours.

I see Massdrop is offering these @$43.99+$8+$3.49 shipping . U.S. only I believe.
All the PT series are listed.

This is what’s inside… everything is neatly put together with a flat o-ring sealing the bezel. The MCPCB is aluminium and quite thin. Will be replacing the LEDs with XP-L HI V2 1A (because I love pure CW tint). There is a solid shelf but seem to be really thin.

ALTUN” also marked on the mcpcb, it seems like all components in this light are proprietary.

MecArmy has a V3 out now. It’s got a plastic sleeve for 16340’s and without 18350’s. GoingGear might have them listed as V2’s. A poster on CPF reported the sleeve from one bought at GoingGear that arrived a few days ago. A few of the German sites also list a V3.

Long term update #1

Since the day of this review I’ve been carrying the PT16 in my keychain and it has been taking some abuse: multiple drops, bumps, gets scratched by the keys and my Spyderco honeybee. It gets daily use and charged twice a week, and works just as fine as the first day.

My claim about this being the best keychain light still stands strong. (if you don’t mind the size)

I just received my V3 after being lost in the mail since december !, to fix my lost I bought a really great replacement wish is the OLight S1R updated version, and I must say this is my favorite light, with the clip(I put it on my cap every days) and the magnetic base and charger this is also a lot slimmer in the pocket and almost as powerful as this mecarmy, now that I just receive this light I do think the pt16 is a little bit brighter than my S1R in turbo mode but on every other specs it loose to the race of practicality smallness and the ease of that charging process, (having to unscrew the top to charge it in the dark its a pain to do instead of just clip it to the magnetic base with the OLight )

if you dont need a clip and dont really need to carry it in your front pocket this light is great and very strong for longer period of time in turbo mod specially. and a plus side with the v3 is to be able to use a 18350 cell wish is what I use, also you can charge any cells with the base wish is not something you can do with the Olight wish require a original cell to charge it with the usb magnetic wire.

both great lights ! love them for different reasons , buy the 2 and be set =)

thanks for that tidbit

the 18350 IMR I picked up with my new PT16 is 2X brighter on turbo than the stock 16340. fwiw The light gets uncomfortably hot for me to hold, within 2 minutes. afaict, there is no thermal regulation within my comfort zone.

Only turbo varies in brightness on different cells, the other modes do not change brightness with different batteries.


The tactical tail got into a scrape with my driveway. The driveway is fine.

The PT18 is modded to 4000k N219b,

its fun having lego options.

Just confused that what’s the difference between PT16, PT16-BS and PT16-Ti, just the materials or anything else?
And why this flashlight is so expensive? what is the unique feature that makes it more expensive than other China-made flashlight?

The larger, heavier noble metal versions feature reflectors in place of TIR optics.

Thanks, did not know Shiny Metals were larger

Yup, Shiny costs extra, and is heavier Smile

there are actually two variants, the Mecarmy PT16 as well as the Blackwater SR71,
more Noble Bling

which one would you like?:-)

there was a copper PT-16 too:

and info here

jon_slider wrote:
there are a couple of differences that might matter to some

advantage SR71
Prices are similar for the anodized version, prices are lower for the Brass and Ti SR71 than the PT16.
The SR71 spec says 5 lumen low, PT16 says 10 lumen (I don’t know if the specs are accurate)
the anodized SR71 seems to use a reflector with glass lens, PT16 has the plastic TIR
the SR71 has a smooth head and tail so easier on pocket wear, PT16 head has cuts in the head to create fins, and the triad tail is more likely to gouge a pocket.

advantage PT16
No copper option for SR71, yes copper option for PT16
SR71 has memory and does not start on low, the v2 and v3 PT16 starts on low, no memory.

equal
both SR71 and PT16 v3, are 18350 compatible

Anyway, whats not to Love about an 18350 PT-16 in LIGHT weight Ano?:

and then, if money is no object TakeMeToo!
