I have several lights from several brands with OP reflectors and AR-coated glass and they all have this artifact, including Convoy.
Thanks for the detailed answer. Perhaps the cause is the color temperature of the LED ?! I am a lover of warm light up to 4000 kelvin, so this artifact may not appear.

Actually that could be. I would guess the different spectrum of warmer tints could interact differently with the AR coating, and again differently based on the color of the AR.

Heh. Found beamshots of Convoy L21a on warm xhp35-HI and custom on cold Osram.

L21A XHP35Hi

L21A Osram

So this actifact depends on color temperature Big Smile
Therefore, you can safely buy M26С Party

Received my M21C XHP70.2 recently. Finally took it for a walk last night. I am not liking the beam profile. The problem for me is the ugly outer rings that bug me. Disappointing for a Convoy product. Wish it had a little more flood and no outer rings. The rest of the torch is wonderful, typical Convoy high quality build.

Edit: Found the orange peel reflector on AlieExpress, just ordered one. Hopefully it will produce (get it- produce; oranges) a better beam.

I ordered a Convoy M21C XHP70.2 version. On first beamshot testing, Turbo dropped out within several seconds. I tested it another time and again Turbo level dropped out within several seconds (at the end of the beamshot video below, the light output dropped significantly, and I thought it was due to thermal stepdown, but apparently it's not.)

When I checked the tailspring, I noticed it had become 'compressed'. Comparing the tailspring with the one in this review, the one on my tailspring doesn't have a spring-bypass wire, and looks like the tailspring collapsed... Currently I don't have a replacement tailspring so am unable to fix the issue.. Sad

 

(I wasn't even using a high-drain 21700 battery. Just used an ordinary Lii-40A 4000mAh 21700 battery that's near fully-charged)

This has little to do with the spring. It may be a driver problem. Except for the TURBO mode , are the other modes normal?

If I borrow the good tailcap (bypassed spring) from the M21C SST40 and use it on the M21C XHP70.2, it has no problems.

 

The tailcap appears to be the problem - in this short video, turning the flashlight upside or down will change the mode.

(4000mAh 21700 battery is used for the M21C)

 

 

M21C brown is the XHP70.2 version, the M21C grey is the SST40 version.

 

 

M21C XHP70.2 tailspring = not spring-bypassed (seems to have collapsed)

compare to the tailcap from the M21C SST40:

Yesterday i got mine. I gotta say that SMO reflector shows amazingly small amount of yellow crap comming from XHP70.2. I’m still surprised. And those rings Swabs are talking about are coming from the bottom part of the bezel ring and sometimes from reflector emitter opening.

Simple solution is to use permanent marker and ink just the opening of reflector and bottom part of the bezel ring. Be carefull not to touch the inside of reflector!

Beam gets improved instantly without rings. I’m gonna heat anodize bezel ring for much better look instead of just painting it.

Truely impressed with SMO reflector!

I just got mine and it has the same ring around the edge. Does not bother me. Nice light. Great price. I like Convoy a lot.

Received my M21C, excellent flashlight, the only thing that does not fit me on paper and that my M21C differs from the measurements of the review are the lumens and the consumptions. The normal for 4,000 OTF lumens is about 15A, and that proportion I get in mine, about 8.5A and 2,700 lumens, very far from the 9A and 4,000 lumens of the review, but still excellent.

I also measured the M21C XHP70.2 at around 8-9 Amps max (tailcap current), which is also similar for the Astrolux FT02S (XHP70.2). Both flashlights claim “4000+” lumens, but my own “guesstimate” (ceiling bounce lux measurement) would be in the ballpark of ~3000 lumens, which matches with the power/current consumption.

I would say the Convoy M21C (XHP70.2) and the Astrolux FT02 (XHP70.2) are very similar in terms of brightness and beam pattern. Both have similar size heads and both use 1×21700 battery. Difference is one uses a tailswitch and the other uses a side-switch..

Anyone tried the new Orange Peel reflector with XHP 70 ?

No one mentioned compatibility with 18650. Is that a non-issue?

I have it. Like it more than SMO cause beam is just perfect. Transition from hotspot to spill is flawless but throw is a bit reduced.

OP makes the light more floody,
IMR18650 can be used in M21C

Thank you Simon,

that means no Samsung INR batteries including 30Q,
only something like Efest IMR, 20A 35A ?

No, he just means 18650s will fit in the light and that high drain is suggested/required. 30Q should be perfectly fine since they can handle 15A (and even 20A, but with significant voltage sag).

In fact, INR batteries can also be used

That’s great, makes sense, I think originally, I got confused by

Quote:
Battery type required: 1*21700 battery

Other 21700 flashlights list

Quote:
Required battery type: 21700 or 18650 lithium battery

What XHP 70.2 color temperature do you guys recommend?

  1. XHP70.2 6500K
  2. XHP70.2 5000K
  3. XHP70.2 4000K
  4. XHP70.2 3000K

M21C will be used as a thrower and I am ordering one with SMO reflector for max throw. ‘
But I am not sure if I should get 5000K or 4000K.

Is the 4000K less efficient in terms of kcd and throw?

i dont think XHP70.2 LED is a good selection for long range light

Sample beamshots of the Convoy M3 (XHP70.2) at close range (around 18 meters or 60 feet from the wall ahead)

(these are the Convoy M3 XHP70.2 6500k, XHP70.2 5000k and XHP70.2 4000k)

 

 

another set of 3 Convoy M3 -- these are the Convoy M3 XHP70.2  5000k, XHP70.2 4000k and XHP70.2 3000k)

 

 

The Convoy M21C has a bit larger head than the M3, so should throw a bit farther than the M3 though.

 

Here I have some 3 beamshots of the Convoy L6, which has XHP70.2 6500k, XHP70.2 5000k, and XHP70.2 3000k.

(distance of flashlight to opposite building around 150 meters or 400 feet)

Convoy L6 XHP70.2 (P2-1A) 6500k beamshot:

 

Convoy L6 XHP70.2 (P2-3C) 5000k beamshot:

 

Convoy L6 XHP70.2 (N4-7A) 3000k beamshot:

 

 

(Convoy L6 also has XHP70.2 4000k, but I haven't tried that, so no beamshot).

 

The Convoy L6 has slightly bigger head than M21C, so it throws a bit farther than the M21C.

Very nice beamshots. Thank you that was very informative. The L6 is really nice.

Now I understand why so many requested the OP reflector for the XHP70?

What LED would you recommend?.
I think the SST heats up much faster than the XHP70, so I assumed the XHP70 will throw and lasts longer. But I could be wrong.
