FW3A, a TLF/BLF EDC flashlight - SST-20 available, coupon codes public

Not entirely sure yet. I think Neal has that process covered, but I don’t know the details.

I don't see the reason why it couldn't have a nice boost driver. I can see a cheaper, not too-hot-on-high with PID being possible. The sc62w has it all on one board (with LED) with a $3 buck/boost driver from TI (although I read its fairly complex and 4 layered with copper core). I don't think that you have to make it super powerful for a smaller light. With scale it can drop it down. But the design of the firmware will be more difficult I believe.

Here is the SC62w taken apart: https://imgur.com/a/luMiX

Still, making a small aluminum isn't impossible if you don't ask for too many lumens. I know this is BLF and we love lumens (my first loved light was the A6), but a small light like the D4 just cannot be used reasonably at its high. It burns paper. It dedomes itself. It can destroy itself from being used. I personally don't want that to happen, although I wouldn't mind more lumens on a thrower, I don't see the point of a flooder/muti much. A D4/SC6x sized light with side switch, nice buck boost driver (or even just boost), PID, killer interface with ramping, programmable modes or groups, some sort of low lumen modes, fits 18650, side switch and modability would be awesome.

I'm so excited that we are moving away from linear regulated drivers, then some into MOSFET, and now boost drivers all while getting smaller and smaller.

Thanks to this forum, there have been so many advances from the always draining incandescent, to the primitive strobing drivers with ugly tints, and now we have nice tints, way better interfaces, and are now even working on efficiency! Its so exciting!

In for one

WOW! really excited been waiting for a loooog looong time for this :smiley: :+1:

Interested in 1. Thank you.

I’m currently 1301. Please secure one more spot for me.

In for one, thanks.

i’m in for 1

Will there be any space for trits in this light?

From previous post I read, it does not have extra material to fit any

Well, you could use some of these drilled optics from azhu in his WTS thread.

Would there be enough material in the tail switch to put a slot for a trit (like the reylights)?

Answered here.

Was there an updated rendering anywhere buried in the thread?

If not, based on the original rendering in post one, the tail button is around 2mm thick. That would require a person modding the light to take quite a bit of care cutting the slot for a 6mm x 1.5mm tritium vial to sit flush without breaking through.

The thick part of the tailcap surrounding the button is about 4mm x 4.5mm, so that’s a potential location.

The shoulders on either end of the body tube are about 2.5mm x 3mm.

Maybe a number of smaller tubes? Fasttech has even 2x0.5 mm. Or 6.6x0.65.

Ok. I’ll just get trit optics then. Thanks for the info.

Toykeeper’s info about the driver (with the upgraded 7135 chips)!just blows me away. This is shaping up to be amazing. I’m putting my money where my mouth is too, I’m signned up for three!

Hi, I'm listed as being down for four (4) lights, but I only asked for two (2). I've only ever made one request post for two (2). See my history, it's pretty short.

(Not sure what happened. I had to double-check this to make sure I wasn't losing my mind. )


Hey, darrylo, you ordered four (4) flashlights.
Check it out, click on the links
See Post: #1250, page 42, : Tue, 09/05/2017 .
The Miller gave him number 588 and 589 on Interest List. TK moved it to 586 and 587 See Post # 4, Page 1 .
See Post: #2132, page 72, Wed, 01/10/2018 .
pepinfaxera gave him number 931 and 932 on Interest List. T.K. left him at 931st and 932nd on the List of Interest See Post # 4, Page 1 .

If it was a mistake, no problem.
I’ll take two from you.
I’ll give you two, numbers 586 and 587.

So… Opened the 200+ new post, and accidentally closed it, and then lost track where I left off.

Read the 5 or so newest pages.

Was there a decision on anodizing? How about emitter and temp? Or at least what emitter and temp was most voted for?

Sorry, try to avoid these types of posts, but made a stupid mistake of putting off catching up on the thread and allowing 200+ posts to go by, and closed it by accident when I did get around to checking it…

No anodizing decision yet.

No emitter decision yet.

You can see the poll results on post #1.

It looks like 5000K temp and xpl-hi is most popular.
