Has anyone seen beamshots of the M21G in the wild yet? A cursory search didn’t provide me with anything. Hoping someone analyzes this light soon. I’m wondering how it compares to the Lumintop PK21 or Convoy L7.
Simon, could you please comment the discussion regarding Convoy T3 vs T2 efficiency on NiMH: Convoy T3 vs T2 efficiency on NiMH? ?
It was said before that T3 should be more efficient, but runtime on T2 is much much longer.
Just a question about ordering from Convoy from Aliexpress….
I ordered a S2+ 519A with the following text:
Custom S2+ Black Body, 519A LED 5700K, forward clicky switch, 7135X8 12 group driver, 38 degree TIR matte lens
Is it normal that the delivery contains a S2+ 519A, with normal switch and lens and an additional package containing a switch, PCB, spring, Rubber dome and a matte lens for self assembly?
Reflector is like 60 mm I think. Tested the PK21 and based on the M21G specs, it totally crushes it. I got over 8000 lumens and 1300 m throw on the PK21. It steps down real quick though on stock Anduril settings…blink and you’ll miss Turbo. The L7 sustains high output better, but the PK21 beats it on output and throw.
I’m not sure, maybe the m21D? I’ve since been able to locate a couple of M21G NLD posts. The beam profile looks good to me! Now I’m just wondering about the sustained output over time.
Interestingly, the 1lumen review of the Convoy L7 and Lumintop PK21 show very different results with with regards to the L7’s sustained output. Maybe a change was made to the L7 driver during the course of its production that would account for this, or maybe one sample was defective in some way. I am starting to see why people start doing their own testing.
L7 has a buck driver. Lm and sbt90.2. PK21 has a fet driver plus xhp70.3 and Anduril. Very different runtime results for sure. The only thing they have in common is they’re LED and have 2S batteries.
I have produced some stainless steel clips for T4.
The voltage value of the FC40 is not the standard 12 volts.
I want to know what is your LED model?
Yes, the size of the drive has not changed.
The production time is about 1 to 2 months.
2700K - 5700K ,flashlight with adjustable color temperature.
This requires installing the same LEDs and using the same batteries to test.I’ll take time to test it.

WOW!
Tell us more! Photos!
I hadn’t heard that the PK21 was FET. That’s good to know. I’ll definitely consider it differently if it really costs over $100. (gotta love the shape of that thing though!)
I guess part of the reason I had questions and doubts was because of 1lumen’s PK21 review. It seems to conflict with 1lumen’s L7 Review. I have no way of testing for myself but I think the L7 measurements in the PK21 review are inconsistent with my sample. I don’t think mine steps down that low unless it runs out of batteries.
What is known about the driver is in the new Convoy M21G?
Can you make this lip a bit longer? It destroys pocket fabric every time
I was thinking of mounting the socket E14 in place of reflector, and glass in Convoy M3-C Host, and using the 12DC led bulb that are available on the market for boats and so on
(from what I gather they do have the power IC built in, so it should tolerate 10% diviation from 12V)
To create filament lantern with interchangeable led bulbs on E14 socket.
I did mesure with multimeter my Convoy M21F GT FC40, I did mesure it's perfect 12V on full brightness across the led wires, and lower voltage on lower brightness levels. So I thought it should be safe to use.
(I know I won't be able to adjust the brightness, but I can just change the bulb to the lower one XD )
Could the the resistance of that bulb be a problem, or should it be doable.
I assume the GT FC40 driver is similar in the M3-C.
This is a remarkable step forward, and the continuous photometrics were very helpful. I’d echo the earlier request for a battery indicator light.
Also, many users will have specific preferences for the user interface, as well as the ramp curve/speed. Would it be possible to design the driver with flashing pads? It would depend on the mcu, but the Emisar or Sofirn sp10 pro pad layout would be the easiest to use. This way the community can fulfil its own software requests without having to bug you in this thread. Thanks!
Excellent news!
Is there a compatible magnet for the T3 tailcap?
I was just wondering if there will ever be emitters other than the SBT90.2 in the L7.
Would love to see something like the FC40 4000K-4500K in the L7 if it’s possible (I already have the L6 with it, but I’ve read that the L7 is much better regulated, so it would be the better of the two to own in the long run.)
Help please?
