Always a good watch. I'd suggest using Google Earth as the ruler shows distance more clearly

Got an M21F with GT FC40 emitter in 1900k and orange peel reflector. The most refined design by Simon yet. I hope in comes in other colours so I can buy another M21F without it looking identical.

How about M21B SFT40? Is M21F better than M21B?

M21F has bigger reflector, so throw should be better on F.

Do you have two cameras for the 600mm video? or do you just sync it in as best you can?

Sadly when I do thrower reviews, I film main video with iPhone on top of my 6D (you can see 600mm lens at the bottom of the video), but that way, video quality suffers :/ But for now, I cannot spend 600€ for dedicated video camera, as I earn 0€ from those reviews. But will try to improve my content as time goes.

Ummmm....how about a comparison with the Convoy M21D (3850 lumens. 21700 cell & XHP70.2 6500k), which I have, hence why I'm watching this video! :-)

Hey, sorry, I do not own M21D. But I did review of M21C-U XHP70.2 4000K. Also I don't think M21D has 3850lm, as M3 has about 3500lm and it is sucking almost 10A current. And without even comparing I can say, that M21F SFT40 will throw almost twice further than M21D (because of LED dye size). XHP70.2 is flood LED :) Right now I am working on S11 XHP70.2 review, so will post it later today :)

@@FlashlightTech -The factory rating on the Convoy 21D is 4200 lumens, and yes it's more of a flood than a thrower, which my Convoy 3x21a (SFT40 6500k- w/5700 lumens-Factory rated @ 6300) is! Both I have set for "tactical" (4 quick button pushes). I'd like to find an EDC size, like this Convoy 21F, but throws/lumens like the 3x21a! Fenix LR35r 10k lumens? :-)

@@kauaikit With lumens it is a bit complicated - if you take 1000lm as starting point, 4000lm will only look twice as bright to human eye. Also keep in mind, that flashlights cannot overcome laws of physics, thus 1500-2000lm is most 500-700g flashlight sustainable limit. It depends what you need. If you need throw get flashlight with biggest head and smallest LED - CULPM1 CSLNM1. Any EDC with >2000lm will step down after less than a minute. Above 5000lm, they will probably start stepping down immediately.

@@kauaikit About rated lumens.. This is why I test actual lumens myself. When I went to University to calibrate 3 flashlights in professional integrating sphere in lab, we found out, that my measuremts had about 10% error to lower side. Meaning all my previous reviews had lumens measured about 7-10% less than actual. Future reviews should have about 5% error.

А я взял такой фонарик со светодиодом XHP70.2 и апельсиновой коркой, теперь я знаю, что надо было брать с SFT40 и гладким отражателем. У меня есть 4 фонарика с SFT40 и они все мне нравятся своим светом и дальнобойностью. По мне это лучший светодиод.

Got this light. Very happy with it, certainly not the most "tactical" but I just find the design to be absolutely amazing. As you mentioned the switch is a little hard to press, my way around it is to click it with the tip of my fingernail, it concentrates the pressure on a smaller area and makes it easier to press.
