Another great video, sir. I have the L21B in SFT-40, and it's a great platform for these throwy emitters. Keep up the good work!!!

[@FlashlightTech]

Thanks for watching :)

[@budgetlightph7814]

Wow. Finally someone did a full review. I also have that variant. It throws very well but the beam is very thin which might be bothersome to some users. You should try the SFT40 variant too. SFT40 have 100-200m less throw compared to NM1 and uses 8A driver but the beam is thicker and spill is much brighter. They're both very useful and runs for hours at 10% with just a single cell and that's my favorite part about these lights. 🙂🙂🙂

[@FlashlightTech]

I replaced SST40 in my L21A for SFT40. Waiting for 8A driver from Simon :) most likely will make review of that, after I finish reviews for flashlights, I have now :)

Thanks for the review. I was looking for this specific review in deciding for the next flashlight 🔦

[@FlashlightTech]

My pleasure!

[@ExtremeSquared]

I have the cslnm1 version. I set the modes in the 12 mode to 50% max. I worry about putting 6A into such a small high intensity LED. But it's also nice how many hours of spotlight I can get on 50% mode without losing that much range. You can see how fast thermal protection activates on 100%.

Great Flashlight, i have the Culpm1.tg led model! 🔦🔦

L21B with Culpm1? :)

Convoy which is the longest range flashlight?

Great video bro. I have L21A SST40 2300 lumens and C8, Convoy are best Flashlight's

[@jonskitch8082]

L21b!!!

[@fazil5648]

How long it run on turbo. L21a

[@verynice1192]

do you have an astrolux ft03? is the reflector same size as ft03?

[@FlashlightTech]

Hello, no I don’t :/

[@jiktakjiktak8508]

Hi, I'm asking for your subjective opinion and ranking by illumination distance, because through the eyes the perception is different live and in photos or video.... I guess it will be: 1.Convoy CULPM1 2. Convoy SFT40 Or other diods - CSLNM1, CSLPM1, SFT40?

[@FlashlightTech]

If we talk about one body and different LEDs, it all depends on your needs. But I always prefer bigger flashlight and more overall output power. My most used thrower is 4x18A sbt 90.2

[@fazil5648]

Please recommend me a flashlight range about 800mtr and long run on turbo without heating and long last battery under 50$

What long range flashlight do you recommend, my dear friend?

[@FlashlightTech]

Hello, depends on ehat you need :) battery life or size, or max range?

[@engineren8023]

@@FlashlightTech hi my dear friend The flashlight I want is bright and will illuminate 1500-2000 meters long range, what is your advice? uptime doesn't matter.

[@FlashlightTech]

@@engineren8023 1500-2000 meter is a bit high, from 300m naked eye cannot distinguish man and tree, and I do not know that kind of light. To be able to light something in 2000m, you need throw of at least 4km and ideal weather temps, that kind of flashlight would be above 6kg i guess.

[@engineren8023]

@@FlashlightTech I got it, so what is a good bright long range flashlight you can recommend to me?

[@FlashlightTech]

@@engineren8023 for battery life I would pick 4x18A sbt90.2. For smaller size l21 b or a with osram LEDs

[@fazil5648]

Sir your information is wrong bcz cslnm draw less current than culpm. In your l21a culpm video the 35% mode exist 1 hour 45 min and in this video l21b cslnm exist 1 hour 36 minute for upto 90%. I think it l21b cslnm should be more than 2 hours runtime on 35% mode.

[@FlashlightTech]

It may be tested with different batteries, I do not remember what I used to test it. I usually tell this info in the beginning of the video.

[@fazil5648]

I have big doubt from those two videos... Please reply sir

[@fazil5648]

@@FlashlightTech but sir the difference is big not little bit. Sir if we use same battery then which runs longer

[@FlashlightTech]

@@fazil5648 L21A was tested with 5000mah battery, while L21B with 4000mah. Also a lot of other things adds to battery life, the longer it sustains high modes, faster the battery will die
