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

Just a quick update…

There should be a new batch of drivers soon, and I’m working on firmware updates. So far I’ve got the following…

  • Fixed the bug maukka found — hold-from-off then release-and-hold in stepped ramp wouldn’t work until it had been on for a full second.
  • Made candle mode slightly more calm but also able to burn a bit brighter sometimes.
  • Beacon mode duty cycle is 100ms now instead of 500ms.
  • Made muggle mode do smaller thermal adjustments.
  • Rewrote most of the thermal regulation code. It should significantly improve pretty much anything related to temperature, except for the lack of factory calibration. (still in progress, running tests right now) It takes a while since I need to test basically every supported light, but the ones I’ve tested so far have all waited a sane amount of time to heat up, dropped quickly to a sustainable level, and then just … stayed there. None of this oscillation nonsense from earlier versions, and so far it has managed to step down at a point which is neither too early nor too late.

Also planning to do some other misc updates, as many as I can squeeze in before the deadline. Not sure which other tasks will get done in time. The top tasks are making “hold” auto-reverse in strobe modes, making momentary do the last-used mode instead of just the last-used brightness (so, momentary strobes), and generally making muggle mode a little nicer. Also debating whether to add ten-clicks-from-off as a shortut to thermal config mode. But I wouldn’t count on any of these things.

The main thing is better thermal regulation.

Gaaah!!!

Going to have to open up my FW3As and flash the updated drivers soon. :stuck_out_tongue:

Could this have anything to do with why my switch has gotten stuck at least twice (and started ramping up to full brightness immediately).?

“FW3C sample?who knows? :smiley:

Nice, I’ll probably end up picking up another FW3A when the new driver and LED versions are in circulation. As always, thanks for all the hard work TK!

Sounds good.
Have you thought about/ would it be possible to incorporate a configuration lock for ramp config, ie the settings for mode numbers, max ceiling & floor can’t be changed unless a code is entered like the H17F or preferably like the LD4Power drivers?
I’ve slipped into ramp config a couple of times & accidently changed settings.
Just a thought.

Thanks for working so hard on updates TK! Now to figure out how to flash new firmware as someone who’s a dumbass.

Yep, it looks to be about ’medium-well’. :wink:

Woohoo!

I received my FW3A today...

(I think it was delivered yesterday, but we didn't get the mail.)

This thing is really small!

It is much shorter than my Convoy S2+ Triple.

So far, I really like it, but I've only played with it for a few minutes.

Thanks to everyone that made this awesome little flashlight possible!

Yes. It’s probably caused by something like that, something physically out of place inside the light. I found similar metal shavings inside an earlier prototype, and sent Lumintop a bug report about it.

I eagerly await momentary candle mode.

Awesome! Thanks for keeping up the good work.

Nope, I don’t have any plans for that. It’s easy to access, but that’s on purpose.

Wow, the FW3A heats up really fast on turbo...

I won't be using that anymore!

I'll test out the flashlight more when it gets dark.

Overall, I'm really impressed.

Nice color!! :+1:

Wait, that doesn’t look like machined copper.

That looks like electroplated copper. :heart_eyes:

It’s easy to see since the knurling has some black imperfections, meaning copper didn’t deposit well on the light.

… or it’s just dirty.

It happens sometimes.

Did we get any more info from @neil on the 219 cri?

Can copper get that dirty?

I though it only gets oxidized/patinad.

I obviously got too excited for my own hype.

I assume if you take your copper light and roll it around in some mud you can get it quite dirty. :smiling_imp:
