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

Well the D4 has that funky coating (what is it ?) which probably has good emissivity so should do OK in a vacuum. Whereas a raw or worse-still polished aluminium body might as well be inside a thermos-flask as regards dissipating heat by radiation.

So we are left with conduction into the hand (important, however blood temperature of 37C is the starting point before any significant cooling takes place) and convection into the air (insignificant, particularly when the torch is clutched in the hand).

Thermal mass is good for soaking up bursts, but this torch has very little, and the energy still has to be dissipated afterwards, by conduction, convection or radiation.

What specifically are you referring to when you say “personnel mixups”??

I agree that the faster the heat gets to your hand the better the heat conductivity. Emitting heat from the host is different again and if my learning from blf is correct anodizing is a barrier to emitting heat. So I’m not sure how Firelight2 came to this conclusion.

However, this light IMO is designed to be more of an edc which means max lumens are not relevant.

Agreed, this torch is about much more than headline lumens figures in short blasts. As an EDC it is very desirable, tiny dimensions for an 18650 capacity. I really like the output from multiple emitters behind TIR optics. The closest thing I have to it is my Astrolux S41 which is a big clumsy heavy dinosaur by comparison.

As TK said, sustained output is on a par with e.g. a Convoy S2 with x8 7135s, but this is so much smaller, and far more potent when needed.

Then there is the UI, and sophistication behind it, thermal management, etc. etc.

And the mechanical packaging, tail e-switch.

I am looking forward to it, however it turns out.

That’s impressive if it can sustain output the same as a S2 given it’s small size. I just hope the emitter board can be easily taken out so you can customize the emitters. So much potential here.

Fritz should of stuck to his guns, it was HIS concept/ design, and then he allowed it to get all BLF’d up! :smiley:

Sure is pocket fondling friendly and pretty now… a real Lady light it is….very elegant… :+1:

Please don’t mis-understand, this torch is thermally limited, thems the laws of physics. TK showed at FW3A, a TLF/BLF EDC flashlight - SST-20 available, coupon codes public - #3271 by ToyKeeper that it has to ramp down after a few minutes, otherwise it would be toast. Subtle firmware.

The point is that it does do so. Unlike most other things.

Otherwise you would have to carry around something like a C8, which is a very different beast.

You make it sound like I’m guessing or making info up. No, the point of the tapered tube was a large discussion here a while back and it was changed to prevent snagging on clothing when removed. I thought it was ToyKeeper that confirmed this, but I can’t find her qoute. It might have been someone else on the Team that explained this. Does anyone remember who?

If I recall correctly, people wanted the tail end to have a taper too, so one was added.

I still think the head-end taper is longer than what would be ideal, making it look sort of like a bell, but it is at least comfortable to hold and clip/unclip.

The surface finish isn’t final; it’s still being negotiated.

I think those are the only visible changes from the original design… and not many seemed to mind earlier when the latest iteration’s render (below) was posted. Maybe it’s just that yesterday’s photos were bad?

OTOH, what I’d really like is if it came in dark anodized purple. :smiley:

Ti ano purple :slight_smile:
Yeah I would prefer both tapers to be the same shorter lengths.

Prettier in Pink :wink:

And without the bell-end.

I like the taper from the head to body. Looks easy to get out of your pocket quickly. If it was a steeper gradient I could see it getting held up on the top of the pocket on any pair of pants/jeans. The steeper taper near the tail cap would also be nice for not slipping out of your hand or from in between your fingers if held like a cigar or something. I have fairly big hands so it’s not always easy for me to take a full grip on a smaller light without blocking part of the lens or being too far behind the tail cap to operate the button. Hence the cigar hold. Raw, Clear ano, gray ano, bead blasted, tumbled, don’t matter to me. I just like it.

+1 :+1: . Well said toddcshoe… you summed it up nicely!!! :wink:

Perfect…… :+1: . As long as Fritz is good with it , it looks like a winner. :wink:

How about a limited run of titanium, mokume, copper or whatever.....

If I understand correctly, if the FW3A sells well, there may later be FW3B, FW3C, and/or FW3T for brass, copper, and titanium.

Hopefully that will happen…. :+1: Titanium would sure color nicely!!! :slight_smile:

To put an end to the tapered body discussion :wink:

The reasoning behind it is indeed to make it easier to use the clip. Having the light I built and the prototype made by LT I can directly compare those two. And the clip of the version with the tapered body is definitely nicer to use compared to the sharp edges. Clipping it in the pocket is much smoother - or rather removing the clipped in light is much smoother with the tapered edge.

Additionally, I can confirm it is still my design. That’s the reason why the the chamfers have a different angle rather than the same :smiley: I like the design like it is now but I am sorry that those design changes ruined the light for some people!

To summarise, putting angles to the body had a practical reason and since it did (in our opinion) not take away from the overall design we didn’t see a reason not to do it.

Finally, I want to add that I think the pictures we currently have from this prototype are a little unflattering and do not represent the design that well. For example this picture of the first prototype looks fairly weird and makes the tailcap look huge while this picture from toykeeper the proportions much nicer and makes the light look much better. So don’t worry too much for now!

Yes & Amen!! :+1: … Thank you sir for putting an end to the speculation & speculative discussion…. :+1:
And a nice design it is too!!! :slight_smile:

Well done Fritz……. :beer:
