Lowest V I see is 10
Bit this is from 2014
Although my English is not good
I am still very grateful to BLF
Especially Tom, TA, Miller, DEL ………
I am looking for a mid size thrower and this is the group that can help me I think. I have an Acebeam T21vn that I run with two 18350’s and I love the 500k lux output, but I hate the UI.
What I would love to have is an SRK style light running off four 18350’s or maybe three or four 26350’s with a T21 or better reflector that would give me 500-600k lux. The main thing for me is the size of the light, it needs to be pocket-able. A 3” diameter and 5 1/2 - 6” soda can style thrower would be a unique light would be small enough to always take along and powerful enough to light up things beyond the reach of my general purpose light.
Is this possible and would anyone else be interested in something like this.
What you say is
Shorten a SRK/Q8 tube so power comes from xx350 cells in series (taking away the drawback of low mAh)
Keep overall outer dimension so a larger (longer) head can hold a bigger reflector with single led to make a soda can light thrower.
Interesting for sure.
No 500-600k light will be pockable…in my opinion anything bigger than a C8 isn’t pocketable
When I say pocketable I am thinking more along the lines of a jacket pocket.
The more I think of this the more I like it
Done in the exact threading as the Q8, wow what a set one would get
use them both stock, Q8 in SRK size, the large head short tube thrower in same size.
swap heads, a longer thrower with 18650 cells and a shorty Q8 with 18350 cells
The shorty tube thrower using a SST40 driven at 7A
See Djozz tests:
we would need 20 x 7135 chips so regulated without FET, ample space on the 46mm driver for this
BLF ST (Short Thrower)
And OP updated with new donations and the spending of $0.90 to cover Paypal fees neal had to pay during testing for mass PM and payments for GT.
Thanks!
I really like this idea too. 
Looks good to me! Although I probably won’t get one, I always like it when things are made to lego together!
I never thought about making the Q8/2 compatible with the Q8, but that is a great idea. You could use the short tube for short duration spotting situations and the Q8 tube when longer runtime is needed. I love it! Put me down for two please!
How does the XPG2 compare to the SST40? I think I remember reading something about it, but my short term memory sucks.
Idk but Olight doesn’t use the SST 40 without good reason 
I’d still like to see some significantly smaller BLF lights, like a 14500 version of the brass AA with BLF driver and high-CRI emitter, and a BLF clone of the Olight S10/S1/S-Mini. Both use small batteries and are small for their battery type.
The goal wouldn’t be to make the brightest lights of their size, but to put a lot of features in a small space, with good attention to detail.
I’d love to see a BLF-348 scaled up to take an AA cell. Same LED, same output, same single mode operation, just more runtime.
Forgot about it, but there’s Carclo 60 mm ultra narrow catadioptric. Low efficiency, but lots of throw in a compact package, you could get 18650 batteries in a light that’s as short as 18350 with reflector.
Agree, some small lights between all these big ones wouldn’t hurt.
With the X5, D4 and future FW3A three small lights fill the void right?
It could be cool to ask Fritz if a shorty 18350 tube for the FW3A is a nice idea.
The Q4/Q2 for me would be about the driver and as such pave the way for lights with cool UI using AA and AAA cells.
The Q8 was about recreation of an iconic light that went downhill
The GT sounded so daring when TA and me were talking about it first that it seemed not likely a manufacturer would cone with such a thing any time soon.
I am really psyched about the Q16 for that already exists in my head and would bring long runtimes for high lumens, high lumens we see a lot, but not sustained for long so this feels like something we should be doing if only to show manufacturers it can be done.
The small lights are being made in such wide variety from $1 to $$$$
The X5/X6, D4, FW3A and Q8 prove a versatile UI is possible. If only a 1,2V input driver can be developed there are bound to be more lights made by professional parties right?
Nope, the X5, D4, and FW3A are still pretty big. I’m thinking more toward the small end of 14500 or 16340 lights —
something with approximately the same total volume as an 18650 battery.
About fans: When 12 Volts fans are to high Voltage, there are also a bunch of 5 Volts fans out there.
Of course there is the waterproof issue with fans…
You could make them water resistant though, but i doubt there are water resistant fans on the market in a small size.
On another note, how about a recoil light?
I started a topic about a year ago, but i can’t seem to get it going.
The problem is finding a reflector…
But, like with the GT, it can be made by a flashlight manufacturer (or they can have it made by a specialized manufacturer)
A recoil light is a thrower pur sang, has no spill and a very tight beam without a corona.
It will probably out throw the GT because it uses practically all of the emitted light from the LED.
It would be unique.
The SST-40 on 5 Amperes seems like a good LED for it.
