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

Oh! That’s what I get for not paying close enough attention. I was under the impression that this was being done for battery life/heat management. What you say makes sense though. Even Anduril on the D4 and D4S has the FET limited on the 219c version if I remember correctly, for that reason.

I didn’t realize the 219b was that sensitive.

Thanks!

Yep, 219Bs shouldn’t be driven at >2.5A for more than very short bursts if I’m remembering right. That’s VERY easy to exceed with even lower-drain cells, they can put out higher current than even the rated burst drain in a FET-driven light.

I just want to make sure there’s no chance of damaging the emitters. It seemed to me that disabling the FET was the safest option.

The 219B is rated at 1.5A, compared to 1.8A for the 219C, so nominally they don’t look much different, especially since the newer V1 219b’s have similar voltage curves to the 219C. However, the 219C is already known to be working very hard on the D4, so the concern is increased when the current your battery can supply is shared between one less emitter, and that emitter has even a slightly lower current capacity.

So dialing back the current for a 219B mod is very likely prudent.

A benefit to modifying the firmware rather than just setting the ramp at a safe level is you retain the short-cut to the firmware max level. Shortcuts are a great feature of firmwares like Anduril.

A firmware modified for the 219B might also be well-suited for the E21A, and Clemence is planning an E21A triple board. However, Carclo says the 219B should have more throw in the 10511 optic than an E21A.

Added some extra info to comment #3 — about the driver, and about the optics and beam pattern.

Also updated status in post #1.

Will it be possible to buy a spare driver?

How about spare clips…!

Please add 2 more for me, thank you.

I have no idea. I’ve been trying to get confirmation on a variety of extras… but most of those questions just disappear into the void. In particular, I’m hoping there will be a diffuser cap made to fit it, to allow it to work as a candle or lantern. But I get the impression this sort of question won’t even be acknowledged until after the light itself is in production.

will it be possible to drive a spare buyer?

Very excited to finally see this come to fruition! Can’t wait to be able to order mine. I’ve got the money reserved :smiley:

I get the impression that you have the patience of a saint.

Justanotherguy brings up a good point, you never know what spare parts you might need. I think I should get the complete master set of spare parts.

Could I have another light please? First one is at 1877.

/\ +1 I agree. :+1:

Good one. …… :beer: . :wink:

If no logo is possible for the GB production, I want two, total, for sure.

I don’t mind the bunny, but I don’t prefer it, either.

It is confirmed here in the thread there is no bunny on the GB lamps.
I also mailed Neal and he said no bunny.

After the group buy there will be one on the tail.

In for 1, please!

Could someone here do me a favor? Please remind Neal that I still don’t have the two GT Micro’s I paid $90 for and the Fireflies E07 he sent instead is still sitting here waiting for his response from a month ago.
Thank you.

:open_mouth::person_facepalming:

I would hope he is following this thread, and that should be a reminder, but if you are waiting for a response from a month ago, I’m probably wrong.

Please add me for 2. Thanks!
