Please note that Convoy's 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.
Haven't heard of the L21B before... If both lights are using red CSLNM1 emitters, then it really does a great job hitting that long distance. I'm impressed.
@@PiercingTheDarkness Very Interesting! It's hard to tell by video, but does it use the same reflector? Considering how much more intense the hotspot was with your L21B, I had to go back to confirm you said you were using a red CSLNM1 and not a red CULPM1... This design is rather nice, the L21A makes some people think of a medieval mace.
@@eckyeckypikang No, different reflector than the L21A, everything has had weight shaved off, that L21A reflector was quite heavy. There's no CULPM1 in red, just the CSLNM1. I still need to run tests, but it doesn't do too bad of a job keeping cool either. I'm ditching the L21A in my store as this is much better. It's only 26mm body diameter which means it'll fit most gun mounts. I'm sure this model will be very popular and hope it shows Simon that lightweight isn't a bad thing.
@@eckyeckypikang Btw, I noticed the L21A is slightly out of focus making it perform worse than this new version. The Green CSLNM1 in the L21A gets 1,560m vs 1,674m
@@PiercingTheDarkness This thing's really catching my interest. I enjoy the output of my CULPM1, but I love all my CSLNM1 lights. I think in a wide reflector like this it's gotta be amazing. Will it be available with a CSLNM1 white? Available for us in the US? Any idea when it might land? (Lots of questions, I know 😂)
Hunting. Many animals can't see red very well and they keep much calmer. It also helps retain night vision and is easier on the eyes. I love headlamps with a red beam as well since it helps to keep insects away.
@@PiercingTheDarkness People also use them when looking through telescopes and astrophotography for the same reason. Some telescopes can be heavy and tricky to set up in the dark. But red light will preserve your vision so you can see more through the eyepiese.
I want a flashlight that has the farthest throw distance. is it correct if i choose l21b cslnm compared to l21b culpm?? I don't need a big lumen, I just need a really far throw to have fun. but my money is limited, i can't afford to buy a flashlight lep. l21a is also expensive for my pocket. therefore I'm still confused to choose between l21b cslnm or l21b culpm. what do you think?
Hi, buy the L21B CULPM1 because Convoy still hasn't corrected the focus for the CSLNM1, so you won't get the range you see in my videos. I was making a custom part for what I sell in my New Zealand store. I'll have the Amutorch BT35 LEP review finished in 2-3 days and I compare it to the L21B PM1, you might find it helpful. The L21A CSLNM1 might be fine though, I don't have one to check.
@@PiercingTheDarkness the focus problem in cslnm is actually just a problem with the gasket, right? If that's the case, maybe I can use a double gasket to fix it maybe. Or maybe there's a problem with the reflector too? if it's a reflector problem, I don't think I can solve it, because the reflector is defective from the factory.
@@miller2432 If you're able to do it yourself, by all means, go for it. It's just the gasket. Get some of these - www.aliexpress.com/item/4000086998352.html - sand one down flat and then glue it to another one. Perfect focus. There's one other way and that's to get the new black 4040 gasket, it's not on the Convoy store, you have to ask in a message for it. This is the correct thickness, the only issue with a larger gasket is the annoyance of centering the LED. I ended up just using this 4040 gasket now, I just apply pressure to one side of the bezel while tightening and it moves in that direction, makes it simple to center. You'll get 100m more range over the PM1, or you could get the green cslnm1 for 1,700m. I absolutely love the range of the green.
For the 4040 gasket, at a local Indonesian shop, there are only white ones for sale. what if I use the white 4040 9mm gasket? will i get a good result like the black 4040 9mm gasket? I once bought a m21a culpm, and the default gasket is black, 4040 7mm.
@@KULAS6463 it'll be centered if the LED is centered when reflowed on the MCPCB. You'll also need to make a custom gasket with the correct thickness if the beam doesn't look nice.
Most likely not since the Osram LEDs are best for my customers. This is a demo video made for my flashlight store. Convoy has currently removed the SFT40, so unsure what's happened

Convoy designed it for me as a lightweight L21A specially for mounting on a rifle. 210g vs 354g :)

It's strange that the Red makes the camera look out of focus. I used a white to focus it in and it was all perfect.
What is the purpose of that red-light sir?
