The problem is that PC fans will most likely have a voltage of 12V.

Most 12V PC fans run fine on 5V, only slower, so 6-8.4V should work.

Yes this is the idea

12V is max, most will keep running down to about 40% voltage, just slower.

Lowest V I see is 10

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. :slight_smile:

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 :wink:

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.
