hey all friends BLF,
I sincerely recommend this BW flashlight to you! BW is a new brand these years with really good value!
The newest product is T1 pro which is a long range torch.
through of 600meters, 2300lumens max. And it’s easy to take.
This is the video fyi
Where to buy:
Ask me anything:）
This seems to be a nice light, I think using the SFT40 LED would have been a better choice (more throw).
The video, however, I find scientifically inaccurate:
First, a parabolic reflector (illustrated with orange rays) is not a 球面镜 (spherical lens).
Second, just because a TIR collects a greater proportion of the emission into the hotspot does not imply that it throws farther–by that reasoning every TIR should be able to out-throw every reflector, which is not true. So the claim that TIRs out-throws parabolic reflectors in general is provably false. The video also does not account for loss via stray light in a TIR, which is usually higher than the absorption loss in a reflector.
Given the same size, the choice between TIR and reflector is down to beam profile preference and has little impact on throw. What the TIR achieves, by collecting a greater proportion of the emission, is a bigger hotspot. Not brighter, just bigger.
I’m not liking it. Here’s some constructive criticism.
Instead of machining on the handle I really prefer knurling and sandblasting prior to anodizing like Elzetta does with their lights.
Crenelated bezels are pointless. Also two tone color is pointless.
The runtimes are grossly exaggerated which is beyond annoying. No way that light can do 400 lumens for 24 hours. Esp with a 5000 mah battery. At best it can do 4.5 hours assuming it has a buck driver.
What kinda driver does it have?
A lot of people on here love very slim lights, I don’t. So I like the fact that this light takes a 26650 cell but I have no intention of using a 26650 cell with the same capacity as a 21700 cell. I hope this light can take the biggest 26650 cell Vapcell offers.
Also, people prefer different tint options. Having multiple tint options is always great.
Like the previous commenter said, Sft40 would have been a better choice and preferably also offered in 3000k tint as well.
Buck driver.
26650 is an odd choice, 21700 is much more readily available.
That’s what I was thinking.
Some BLF member like 26650 lights, but I prefer 21700 lights. 
I like the look of the light, but the video has some mistakes, and there’s some other things that would keep me from buying one.
It looks to be using the same optic as a Sofirn IF22A (and a bunch of other lights), and the knurling and design is very distinctive of Mateminco OEM.
It probably uses a similar driver to whatever the latest rebranding of the Mateminco MT01 uses, which might indicate FET or linear.
I’m curious to see what the UI is like (hopefully it is click to turn on/off, hold to change modes), and some real world performance figures.
I would have recommended the Luminus SFT40 (available in 6500k, 5000k, 3000k) instead of the older SST-40, and having it available in multiple CCT options.
If it is anything like the Mateminco MT01, the tube is slightly too narrow for the highest capacity 26650s, but it can fit a 21700 with a spacer to fill in the diameter.
TIR is nothing special, and 26650 is not a good choice for new flashlights manufactured or designed after 2019. SST40 is a cheap lumen option but has too much of a green tint and the flashlight isn’t essentially cheap. XHP50 Hi or SFT40 would be better.
Thank you very much for all your sincere replies!
Some of you like the style and some of you don’t, all replies are very important to us! I really appreciate it. I’ll collect all your advices and send to our designer.
Then I’ll put more products from BW so you can see if you like it:)
Dear all,
back again 
Please see BW-C1 which is the bestseller of all BW products. 1800lumens max , 200 meters of through. And it’s very easy to carry and use. See if you like this simple style of flashlight.
Crenelated bezels are neither pointless nor without function. I’ll bet if you think about it for somewhere between ~20 seconds and six thousand hours you’ll figure out what practical function they perform.
Let’s hear what it is!
Im genuinely interested in what the use is because i find them more of a style thing rather than having a use. Unless ofc its the wurkkks ts30s murder bezel lol
Ostensibly they’re good for breaking glass and murdering although I’m pretty certain that in 99% of cases a crenulated bezel, while doubtless better than nothing, would struggle against a car window. Not that I’m planning to test it.
That said, I do quite like the style as long as it’s not a full-on murder bezel, so it wouldn’t stop my buying a light that had one. I wouldn’t buy a light with an SST-40 and an unregulated driver though.
You can know if you accidentally kept the light on while putting it down head first on a table.
I don’t ever put my light down head first and I use this as a glass breaker

I keep multiple of those in my car
I’m not having a go at you because I’ve heard that a lot, but it always seems like a bit of a reach. I mean, sure, if you put a light head-down on the table you can tell that it’s still on but how many of us have actually done that?
I have always thought a bezel where you can tell the light is on when placed bezel-down on the table is a good idea. I know I have put a flashlight on table bezel-down many times. Especially ones that might roll away otherwise.
How many times have you put a light bezel-down without switching it off first?
I dunno I try not to. Maybe once, twice? That is the whole point. It is a reminder in case you did not turn it off or thought you did but did not. I am fine with crenelated bezel. I don’t care for murder bezels or anything gaudy.
I’ve turned my S2+ around a bunch of times to check if they are off. Not an issue on for example my S21E with the crenelated bezel.
Correct.
For those who can’t fathom this, imagine for a moment that some people do actual work, and use flashlights to do so. In the course of the work, the flashlight gets picked up and set down over and over, and it is not always turned off in the process, and it is sometimes totally forgotten about in the course of the work as one task turns to another. A crenelated bezel helps you to notice that your flashlight is sitting on your bench or toolbox, etc., in the ON state.
