Convoy S21B CULPM1.TG beam shot review

)
Convoy S21B CULPM1.TG 1800lm
The flashlight is the same size as Convoy S21a but the throw distance is amazing. It has a tight spot and can throw 200-300 meters away despite having a small reflector. Very powerful thrower in a handful size.
18650 or 21700 battery
No information about runtime.
Thanks for watching.

Weerapat, I only started collecting flashlights in April this year. I had a lot to learn but in three months I've learned quite a bit about drivers, emitters, reflectors, beam profile, thermal stepdown and batteries. In three months I've bought nearly twenty flashlights and three of them are Convoy with green emitters. My latest Convoy is the S21B with the CSLPM1.F1 but it doesn't throw as far as the M1 with the CSLNM1.F1. 😀 🔦💚🔆

[@MrQuackism]

Very fun to play with. I received mine S21B one week ago with OP reflector. Awesome.

[@weerapatkiatdumrong]

Thanks for watching sir.

[@IsraelMagalit]

Extremely impressive throw for a small diameter flashlight.

[@weerapatkiatdumrong]

Agree sir. Throw like C8. Thanks for watching sir 😊.

[@DerTou]

I like this flashlight. 21700 gives good compromise between size and battery capacity. I think it's a good alternative to S2+

[@weerapatkiatdumrong]

I agree with you sir. Thanks for watching.

Hi can I use battery from Nitecore. Bottom top

[@Thrael72008]

Hello @weerapatkiatdumrong I know this is an older video but do you thinkg that 6A are enough for the CULPM1? Would the 8amp driver (like in M21B) drive it better? I 'm a bit concerned whether the 6A limit would make the CULPM1 perform like a smaller W2 (CSLPM1).

[@weerapatkiatdumrong]

I think 8a might be better sir. Thanks for watching sir 😊🙏.

[@Thrael72008]

@@weerapatkiatdumrong To be honest I ordered the 8A M21B last night before I had read your reply. Thanks though. We seem to be thinking alike. 😀

[@SodiumSyndicate]

Why by a C8?, it uses only a 18650 battery, if you buy a 21700 flashlight, you can use both 21700 as well as 18650 batteries in it - Multiple redundancy.

Nếu tui gắn gương phản xạ OP, cho CULPM1. S21B, nó có ảnh hưởng tới tầm chiếu xa nhiều không? sir. Vì khi gắn lên S21B CULPM1.Nó có một điểm nóng tròn sạch sẽ rõ ràng nhìn đẹp hơn gương phản xạ SMO.Thank you Weerapat Kiatdumrong.💚.

[@MrQuackism]

Brother. Quick question. I have a S21B, 4 mode. On website it says lowest mode = 0.1% So does that mean the lowest mode the lumens is 2400lumens X 0.1% ? Because on the lowest mode I feel th e 0.1% is way brighter then 2.4 lumens

[@weerapatkiatdumrong]

To be honest, I am not sure sir because Convoy never gives detail about lumens in any flashlight. I also think that level1 is brighter than 2.4 lumens. Thanks for watching sir.

[@dikygustian]

Permission to ask my convoy s21b sft 40 suddenly won't turn on, and only lives in 0.1% mode, the battery used by Samsung 40T is standard driver. Use more often at 35% and even then rarely continuously and in 100% mode. Guess why? Is the driver dead?

[@weerapatkiatdumrong]

Hello sir. Check the brass ring first whether it's tight or not followed by the battery. The worst case is the driver is dead. This may be due to short circuit caused by the reflector touches +- wires. If you cannot fix it. Just buy a new driver. It's also possible that the led is dead too. I experienced this with my sst40. Thanks for watching sir 😊🙏.

[@home007u]

I did chat with 2 stores at aliexpress and they both said max.2300lumen I am also skeptical that 6A driver can really output 2300lumen? 1800 to 2000 lumen seems possible

[@weerapatkiatdumrong]

Agreed. 8a driver may be possible to give 2300 lumens. Thanks for watching.

[@yourfilipinotv6477]

Which is better? S21B in culpm1 or sft40?

[@weerapatkiatdumrong]

Sft40 is more powerful and wider beam sir.

[@MrStickmanish]

Hi, I just bought the S21B but it keeps turning off by itself… All the modes just light for 3 seconds then turn on and it goes like that, there is just one mode which is like a continuous light but after 30 seconds it completely shuts off and I have to click 8-10 times before it starts again and lights for maximum 30 seconds.. I will check with the store if its faulty but decided to check here if maybe Im doing something wrong..

[@weerapatkiatdumrong]

Hello sir. First check the battery whether it's fully charged or not. Second, what mode ate you using (out of 12 modes). Check the brass rings at the + and - side. Make sure they fit tightly. I hope you can fix it. Thanks for watching sir 😊. Please subscribe 🙏.

[@quackster4419]

Check the contacts of the light. Remove the head and tail and clean the metal contacts with alcohol

[@MrStickmanish]

@@quackster4419 thank you both, I did all of that and it turns out that the battery charger is doing tricks - when I put the battery in the charger light goes green (it should be red if its charging and green if its full) so it turns out I had to pull up the battery a bit to place it just right on the charger otherwise it glows green and I though that the battery is charged.... Thanks again, its working fine now!

[@zrscoolvids1369]

Hello WP, what battery are you using for this flashlight? It says max voltage is 8A but many 21700 batteries are rated quite higher than that.. Thanks in advance

Good video, is there a strobe mode on S21b flashlight? And what is difference between driver 12 groups and driver 4 mods? Thank you sir.

[@weerapatkiatdumrong]

Yes. There's a strobe mode sir, not hidden strobe. You have to buy a 12 group. You can select the mode that you want from 12 group driver. But for 4 moded, there are only low med high turbo. No strobe. I prefer 12 groups because it's more advanced and there are many group modes to choose. Thanks for watching sir 😊. Please subscribe 🙏.

[@weerapatkiatdumrong]

@@miloscvetkovski7526 S21B SST40 and M21B sst40 have the same 22mm driver. They use 21700 battery. M21B is more powerful because it has bigger reflector. It with give you good throw (250m++) with useable spill. For S21B, it's quite flood with some throw (within 200m). You should have M21b. It is really good and parts are easily available.

Sir, is it the host getting same hot at 'high' (4th mode) like yours S2+ culpm1 on 'turbo' at the same timing?
