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

Can you put me down for 2 please?

A couple of times welcome to BLF!
Will update list later :wink:

Thank you the Miller :slight_smile:

Please put me down for 2 lights

Thanks
Slow

Damn im late, but still in!

Count me in for one. Thanks!

In for 1 please!

I will go in for 1 of these as well. Thanks Miller!

Put me in for one, please!

Would love to be on the list thanks!

One needed, thanks…

I looked quick, but didn’t see… What’s the driver? FET? Approximate lumens and amps?

Put me in the list for one.

me to please.

It is tight bu twe are looking at a
AT85 MCU
FET + 1 + 7
1 7135 for lowest modes from moon and up to 350mA
then the extra 7 7135 kick in for regulated output of 2800mA (I estimate ittle over 1200 lumens out the front but a no expert :slight_smile: )

Will updatelist later

This should be fairly similar to the D4, except:

  • Tail switch instead of side switch. (both momentary electronic switches)
  • 3 emitters instead of 4.
  • FET+7+1 driver instead of FET+1 (so, more efficient and higher regulated modes).
  • Narsil UI instead of Ramping IOS UI.
  • Different body style.
  • Extra pin wired up for aftermarket light-sense hacks.

At a guess, probably ~140 lm on the “1” channel, ~1000 lm on the “7+1” channels, and ~3000 lm on the FET channel. With smooth ramping from moon all the way to maximum. Or discrete levels if you prefer.

Anything up to 1000 lumens should be reasonably well-regulated.

I’m assuming I should (or someone should) probably put in some proper thermal regulation before the FW3A is released, but that probably won’t be too hard.

Putting in a blink at channel boundaries shouldn’t be hard either, but it depends on if that feature is desired.

Please add me to the list.

Hi, please add me to the list for one.

Thanks!

If I absolutely had to choose between one, the D4 or this, what would you suggest? I mean, I will probably end up getting both to feed my crippling flashlight addiction, BUUUT, if I had to choose?

Yes agree after reading that you wrote the stepdown is more for bigger lights.
(Though it would be nice if you care to explain what is the difference, is it that smaller lights heat up faster so thermal stepdown should kick in sooner then actually measured?)

Is there enough memory space for an extra operation group?
now it is
1 ramping 2 modes, factory default 1
could that become
1 ramping smooth 2 ramping with blink at channel boundaries (same operation as 1) and 3 modes, factory default 2 (for in this small light with just one cell it is more important to know the regulated settings)

also with 8 7135 chips a few extra mode groups added seem logical to me
excluded moon or that is different setting
low (1x7135) - low med (2x7135) - med (4x7135) - low high (8x7135) - turbo/high (DD)
low (1x7135) - med (3x7135) - low high (8x7135) - turbo/high (DD) OPTION 1
low (2x7135) - med (4x7135) - low high (8x7135) - turbo/high (DD) OPTION 2
low (1x7135) - low med (2x7135) - med (4x7135) - low high (8x7135) NO turbo/high safer modes
low (1x7135) - med (3x7135) - low high (8x7135) - NO turbo/high safer modes OPTION 1
low (2x7135) - med (4x7135) - low high (8x7135) - NO turbo/high safer modes OPTION 2

OPTION 1 or 2 depending on what is perceived as most evenly spaced
right?
