Please note that L21B CSLNM1 focusing of the LED isn't spot on like what's shown here, so you won't get the same range. I've focused these units myself by increasing the height of the reflector.
I'm working with Convoy to produce the correct LED gasket to fix this.
For my New Zealand customers you only get the best of the best, with the correct focusing.
So with unadjusted focus if i looking for throw flashlight should i go for CSLNM1 or CULPM1?
@@nagaterbang5833 hi, both have now been fixed
@Piercing The Darkness noted, thanks!
I'm a new comers in flashlight, i have convoy s2 and looking for my first thrower flashlight
Which one do you think is more suitable for me CSLNM1, SFT40 or XHP 35?
I skipped the CULPM1 due to tight budget..
@@nagaterbang5833 SFT40 is best in my opinion :) . I don't think the XHP LEDs are focused correctly in the L21B model, but okay in the L21A.
@@PiercingTheDarkness ok I'll go for sft40
One last question, looks like my local seller bought the convoy around december 2021, is there any adjustments on the gasket for SFT40?
Btw greeting from Indonesia!
Thank you so much for your work! Amazing reviews and wonderful location!
Hey man, nice beam shots as usual!
Good luck with building all your L21bs. Looks like I'm going to hold on to my L21a for now, the hunt for more throw continues!
Maybe get the Noctigon K1 then :) . I think we may have reached a limit on throwing range for this size of reflector, the only possible way to achieve more throw would be a smaller LED or an LEP
@@PiercingTheDarkness The reason why I love throwers is because they are fun.
I really enjoy convoys because they allow me to experience massive throw on a budget. As much as I want a LEP, I'm not about to dish out 200 bucks just for the fun factor. If I would have an actual need for one (like mounting it to a gun) then it would be a different story.
I just ordered a convoy c8+ with an Osram cslnm1.14 deep blue emitter, now that is fun on a budget :)
@@PiercingTheDarkness what is LEP?
Man idk where you live, but these outdoor areas are really beautiful. Amaizing nature 💯
New Zealand :)
You are delivering some of the best flashlight videos on youtube. It is also apparent that you spend a lot of time to make these videos. I would have liked to see a comparison of the CULPM1 and the CSLPM1.TG in the L21b host.
Thank you.
These were mostly done for my customers and I don't stock the CSLPM1 so that's why I didn't include it.
It's a shame Simon isn't persisting a little too get that LED 'just right'. I wonder what his reasoning behind that is. To be honest ALL 3 lights are pretty phenomenonal when you consider what we were using 5-20years ago. Big 10" or 12" reflector spotlights. To be getting better performance from a single cell small light you can hold in you hand is crazy. Both L21's lit up the 550m target so well I think ANY hunter would have to be happy with that. Thanks for the great footage. CR888
Simon has a gasket in production, but who knows if it'll be as good. Can't use the 8A driver if it's going to be mounted. The only fix is to solder the spring upside down since the pad is so small. I use a stiff beryllium copper spring
I have 100x L21B's to build up :/ this is going to take awhile. I started gluing the gasket to the mcpcb to get the perfect centering as well since these Osram's are very fiddly
Is the problem when using a centrefire rifle that the recoil is enough to momentarily disconnect the circut so the light ends up actually being turned off? I think you gave me a link for nice thick berrylium springs on Ali-X. For me they need to be fit for use on .22's small centrefire 223/222 to my .270 & .308. It's about craydling/supporting that battery cell. Also I've been testing 2 K64 Vapecels for about 5weeks. Measuring voltage everyday for first 10 days then each week. Stabilisation IS a problem but not a big one on my poorly edumucated opinion. I also did a 50E, Mollicel (vapecel/) P42, T14 18350, the 6A red Vapecell 26350 & a couple of others just to see how they did as well. While not very scientific, I should do a thread with the results. Always enjoy the beam shots.
@@aussiehardwood6196 In the past when I was using the stock springs it would change modes after every shot, on Turbo it would change to low. This is using a .308, a .22 wasn't an issue. I now install dual springs where possible and have a spot welder for adding button tops. I haven't had this problem since . A button top also protects the top from any denting from the spring which could possibly stop the safety vent opening.
Must have been someone else who gave you a link for springs, I got mine from a blf member "BlueSwordM"
@@PiercingTheDarkness Yeah I have the springs in my 'cart' which are said to be heavy duty berrylium. As we speak I am unboxing a little Sofirn D25s. After watching your review I had to get one. My larger Perun Olight is powerful but bulky, heavy and awkward. Pitty the D25s comes with a 2200mah cell but I've got plenty of others to swap it out. Also My K-64 cells one of them self discharged to 1.66v from fully recharged at 4.2 so those cells definately have issues. I had to recharge it and when I did it measured 6700mah of capacity on my Nitecore charger. If those cells didn't discharge they would be great. Maybe there is a reason most 26650's are 5-5500mah.
New gasket is available if you ask Simon, not sure whether it's used in the current stock yet
I have L21A SST40 2300 lumens and C8 1000 lumens, Convoy are great flashlights!!! Nice review bro
100% detailed video. Many tnx dude. Can you pls tell that L21b xhp35 hi 4000k version will reach to 900+- mtr?
I have no idea since I don't own an XHP35 HI to test
Sir what is difference between 8A vs 6A driver. Tell me in detail. I have zero knowledge about this.
Despite the CSLNM1 in the L21B getting 105 meters further range, you must understand that for ANSI FL1 rating you need to halve the range for usable lighting. 105m would only be an increase of 52.5m, this is why there's no noticeable visual difference since it's minimal. In saying that, it's impressive to get further range at 5A instead of 8A of the CULPM1, so if runtime is more important then it's a significant increase in battery life
how would you recommend i re focus my cslnm1.tg c8+? the hot spot is off center, kind of an egg shape. thanks 😄
Just sounds like it's not completely centered. Remove bezel and reflector, loosen screws and move led mcpcb around to try focus it. Wouldn't affect range much, only an issue shining on a wall close up.
Simon has 2 gaskets for the CULPM1 - black and white. Is the black, thicker gasket the right one?
Factory screwed up the latest C8+ batch so now the thicker black gaskets are used in them. The L21B PM1 with my black gasket is the correct one
L21b compare with the astrolux AaE02. Witch one better beam for searchlight.
That will come down to personal preference. Both have have pros and cons.
EA02
Pros: 26650 compatibility, Anduril for mode flexibility, Lvl 6 runs for 8+ min, built in charging.
Cons: Unregulated FET driver and this also causes tint shift to blue with a high drain cell
L21B CULPM1 version
Pros: lightweight 212g vs 287g, regulated buck driver, no built in charging is a pro for some, gun mountable.
Cons: minimal heat sinking
The driver uses a timer that begins stepping down after 2 minutes and settles after a further 7 min. This could be seen as a con to some people, but I see it as a pro because you can continuously reactivate it if needed.
Both are very similar in range. I'll leave it up to you to decide what suits you
Just to clarify on one thing, during your Convoy Z1 video, CULPM1 was throwing farthest of them all with 959 m and with SST40 was only 590m and CSLPM1 was 896m. And in this video L21B, CSLPM1 was 1,450m? It seems that it is better to get L21B with CSLPM1 rather than Z1with CULPM1. Is it? Thanks
Different led in the L21B, it's the CSLNM1, not the CSLPM1.
@@PiercingTheDarkness Thanks. My mistake. My eyes are not seeing very clearly with these LED model numbers.
Bro, my c8+ cslnm1 came today and its out of focus, bro can you teach me how you tweaked so that it'll be centered? Thanks
Those Osram chips are almost always slightly off center, but it's not something you can notice when used for its intended purpose, long range.
Remove the battery > unscrew bezel > remove bezel, reflector, glass, centering white plastic gasket > undo the two screws and adjust the LED whichever way it needs tweaking > reassemble
@@PiercingTheDarkness thanks
Nice Video again!! I'll try to mod L21B with Sbt90.2 though.
That'll get hot pretty quick though
What is the recomended batery amp for c8+?
Which C8+? Different LEDs and drivers require a different amperage
Hey bro, what about L21B SFT40? Is that true it can throw 1258m?
No idea, I don't yet have one. Not sure whether I'll get the SFT40, I prefer a narrow beam for mounting on a rifle since you don't get any glare off the barrel or suppressor. Might use the SFT40 in the L21A instead since this L21B heats quickly at 8A, use it perhaps as a search light
@@PiercingTheDarkness,, Now i just use Lumintop GT Mini NM1 and feel satisfied, so i intent to buy this Convoy model as well. Right now I can only found L21B with SFT40, capable of 1258m which i doubt little bit. Honestly, i'm waiting for you to review Convoy L7 SBT90.2 which is said to be able to reach distances of 1500m..
I want to buy L21B. Which of the three LEDs would be the best choice? CSLNM1/CSLPM1/CULPM1? The latter is significantly more expensive.
P.S. I wonder why Convoy does not release this flashlight with CULNM1 LED? Is there a reason for this?
CULPM1 since Convoy hasn't yet fixed the focus of the CSLNM1/CSLPM1 which results in 200m less range than what you see in my videos. I also really like the SFT40.
No idea about the CULNM1, I've never used one, but I think they're harder to source and a bit more expensive
@@PiercingTheDarkness i has been try CULNM1 on convoy c8..and it similar to CSLNM1 beam but the tint not going to turn blue due to CULNM1(4040)15w more higher rating from CSLNM1(3030)10w and still can hold 5a current safely..then i change the driver with blf a17dd then the tint slightly start bluesh a little bit on higher mode..for the range are not so noticeable much different by naked eye but i'm pretty sure if it measure by meter it will be more kcd than CSLNM1..the price for CULNM1 almost same as CULPM1 and it's hard to find..The another factor i think more important to build a good thrower are not just about the diameter size and deep of the reflector..but the angle of the reflector should be matched with emitter viewing angle and the buttom hole size of the reflector and the thickness of gasket are most critical key..convoy should try make one new reflector with buttom hole size perfectly fit to the emitter without gasket or 5mm or new design reflector with thread..so it will be properly center in the middle just what i'm think 🤔.
Thank you for posting this video. I understand that you tune up the Convoy lights that you have before you sell them. I live in the US and I'm wanting to get an L21B. I understand the the CSLNM1 probably has the greatest potential to throw the farthest, but I keep reading about them having alignment issues in the L21B. I'm not reading the same for the SFT40 emitters. In your opinion, which of the L21B emitter offering have the best throw out of the box? Thank you for your time.
Hi John, I'm not sure, the L21B originally had a focusing issue and I had to correct everything for my customers. This has since been fixed, but no idea if it's as good as my measurements, I'll know in roughly 4 weeks when I get new stock. Regarding the centering of the LED, yes, the Osram chips are so small that it's difficult to get them perfectly centered in the Convoy models. Does it matter? No, not really, you may only lose 40m ANSI and get an ugly shape on a wall, but these are for long range and it's not something you're going to care about at 50m+
@@PiercingTheDarkness Thank you for the info, that is very helpful.
👍👍👍
Which run more on turbo l21a vs l21b with less heating..
The CULPM1 and SFT40 use the 8A driver, this uses a 2.5 minute timer on turbo, so both the L21A and L21B operate on Turbo for the same amount of time. The L21A would heat up less though. I enjoy the L21B because it's much lighter.
@@PiercingTheDarkness is any mode is available without timer
@@fazil5648 Only turbo has the timer, it can't be disabled, but you can just reactivate turbo if you need longer.
Which flashlight would you recommend which is better to buy M21A CULPM1 6A or L21B CULPM1 8A? Will the long-range difference be large?
Hi, that's hard to answer since I've never tested the 6A version of the C8+/M21A, only the 8A version.
C8+/M21A at 8A - 977m
L21B - 1325m
@@PiercingTheDarkness Is the size of the M21A and L21B CULPM1 hotspots the same? And what about the heating in the L21B? I plan to use the flashlight in turbo mode. And don't the modes get lost from the vibration on the driver without a spring?
@@user-wr3io6yy7k Once I get a clear night I plan on making a video of the C8+ SFT40 / CULPM1 and the L21B SFT40 / CULPM1. This would give you a great look at the differences.
The L21B has a narrower beam from the deeper and larger reflector.
I haven't noticed any issue without a spring, but for most models that don't use a spring on the driver, I actually install my own custom spring.
The 8A driver starts stepping down after 1.5 minutes, the step down takes roughly 8 minutes in total. Since this is on a timer you can reactivate as many times as you like, however it's already at 50°C after the first stepdown. If you want better cooling then either get the 6A driver or buy the L21A CULPM1
@@PiercingTheDarkness M21A SFT40 is a very wide beam. In the 8A driver, the stepdown works on a timer, there is no thermal control? Thanks for the answers.
@@user-wr3io6yy7k Yes, the SFT40 is a wider beam, I'm just making a video for my store.
The 8A has no thermal limit, just a stepdown timer on 100%
In the end, who do you think is the strongest lantern of the three?

Awesome video thanks! You mentioned that the C8+ CSLNM1 is 250,000 Candela on the highest setting.. Simon at Convoy says it’s 140,000 Candela. Is it actually 250k? Crazy if so!
Found out a batch of Convoy drivers were pushing that led way too hard at 5.7A instead of 5A, that's why the C8+ has a blue tint. I usually still get 962m at 5A though.
Simon measures only at 5m, while I take mine at 20m. It always makes a significant difference.
@@PiercingTheDarkness Ah right! Fair enough. When you say 5m do you mean 5 metres?
@@justcallmebosss yes, 5 meters. I measure at 20 meters.
