Do you mean the ChangDa ones? (SFH55 and similar)
Tbh these were not so great in terms of efficacy and luminance. The LMP ones are better, even with the under-spec light flux.
This is my favorite clip my friend. I have lots of these and i have installed them to many of my flashlights. The reverse clip that i suggested would be very handy i think with flashlights with bigger head like C8+, etc. You could latch it to your belt or even inside your pocket, since the head would be upwards. Also, the weight of the flashlight would balance nicely.

46950 battery tube/option for all 3x21 and 4x18 flashlights.

I notice a lot of my Convoys, at least the boost drivers, flicker a bit on 0.1%. Being unfamiliar with driver circuit design, it seems these are not “HDR”. You are lucky if Simon picks a 0.1% level that does not flicker, but often then its pretty bright.
Or at least some hardware transparency so that anyone could port any firmware to the driver. I have little hope for this unless Simon adopts an open driver itself. The UI is the Achilles heal of all Convoy lights.
Each listing should have a list of components that are compatible with that host (lens, o-rings, etc). And under accessories, each accessory should have a list of hosts its compatible with.

In order to support a new light model there would need to be demand, would you buy an M21B in Titanium with copper head?
- 12 groups for M21F and M21H. Both have great form factors but currently with horrible UI.
- Make T4 compatible with 3.7v so it can take a 14100 cell like the one provided with Acebeam TAC 2AA.
I believe the 12-group UI is for mechanical switch only. For an e-switch, Anduril is preferable.
Slightly niche request given that the 14100 cell is highly uncommon, but will add

I’m going to suggest to Simon that every new host gets sent to a select few testers. This way everything gets checked over before mass production resulting in fewer surprises.

Companies are often attending only CRI snobs or tacticool guys.
I bet a survival flashlight with very high battery capacity, like 4x21700 or 46940, efficient driver and leds, extra waterproofness layers and robust design would be a success.

Convoy is Simon’s business and he takes all the responsibility. It’s okay someone criticize him or his products, and SUGGEST good solution, but Simon is the decision maker and no one can’t control Simon.
In this conversation, I feel someone pose pressure on Simon. They say it constructive suggestions, but to me, it seems they want to control Convoy / Simon for their desire.
I believe way of expression is very important in communication.
5 Thanks
No one is trying to control Convoy. These are suggested fixes, some minor, and others that have proven to be important.
One example is the 3X21C needs dual springs and shorter screws. Without these fixes the springs are overheating and emitters are de-soldering themselves. Another is the M21J reaching 90°C at only 30 minutes into a runtime. Most cells have a max discharge temperature of 60°C. That can be very dangerous if left on in high or turbo.

I have seen many times Simon warns about overheating like “burn hazard” or explanation in product description. And also he reduced max current for some drivers not to burn it. So, he doesn’t ignore danger which may happen, and makes some effort to mitigate risk.
It is good to tell him the fact if a problem happened or expected to occur. How to deal with it is up to Simon. Is it a bad idea?
I’m seeing quite a few Convoy T8 with beam convergence issues over on Reddit, too, so I think this needs adding to the growing list.
As Simon is well aware of reflector/gasket issues with some emitters on the L21, C8+, etc’ & has been for what seems like an eternity & still contines to churn them out, though, I’m not sure this will be addressed appropriately either.
2 Thanks
I think I vaguely recall a post like this too. Fortunately, neither the gasket nor reflector is actually defective, just that they are a misfit pair, which is easily fixable by sanding/padding the gasket.
Nah, some reflectors are no good for any emitter, this is the case for the L21 9mm reflector. I thought my SFT40 was still throwing the same as the previous batch, turns out the convergence issue was causing my light meter to read too high. About 10m out the beam widens right out and isn’t as bright downrange even though both reflectors measure similar in range.
Interesting to hear about the T8 because mine arrived for review and the beam is spot on, couldn’t look more perfect. I did get it with the SFT25R, so perhaps a different reflector is used for the NM1 or SFT40.
3 Thanks
Agreed, I have the same issue with all of my SMO S2+ reflectors, and at least one C8 reflector. I just meant that the T8 does not appear to have an obvious defective reflector issue.
Had another close look at my T8 and it does have the convergence issue as well. Beam increases in size way too close and is massive at 150m. I’m not personally bothered by it though, the SFT25R still throws a good distance. I don’t have a good reflector to know the difference, if a better reflector threw 100m further, then I’d probably be annoyed.

- I’m all for Anduril, but as far as I know Convoy has not implemented Anduril 2 in any of their lights.
- I, and I suspect others, already have 14100 cells (and spares) in the aforementioned Acebeam TAC 2AA and the Nitecore MT2A Pro. I like the 2 x AA form factor and, of course, the 14100 gives you twice the runtime of a single AA size cell. Also, you avoid the inconvenience of making sure that you have two balanced 14500 cells running in series.
Adding stuff like this to a description is pointless. A proper driver must not overheat. The thermal protection on some convoy drivers is simply inadequate and unacceptable, as they only throttle 1-2 levels down, and the light still overheats, just slower. I avoid those driver/light combos and would never use one.
Simon would have to pressure his software developers to implement proper throttling that goes as far as necessary until the temperature stays in safe levels, as for example Anduril has. The hardware can do it, it’s just a software issue.

I understand your opinion. But there are various kind of users; someone seek for perfect safety, and others want as much lumen as possible even if it gets hot and can’t be used long time. In fact, I saw some requests on Convoy’s flashlight to raise max current. This means the flashlight is set to conservative level, and the users want more lumen which lead to more heat.
As to Anduril, someone use it in default settings, and others decrease the ceiling level or disable turbo mode to avoid heat and shorter runtime. Convoy’s 12 mode groups is not as flexible as Anduril, but by using group 8 for example, output can be limited to 50%.
As these flashlights are for enthusiast, not for general consumers sold in home depot, I think users can control the product properly if enough information is provided. To be enough or not t be, that is the question…
