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

.

:+1:

Two flashlights for me please!

O. K.

weight?

. . . ?

Last year, these were Fritz expectations, in the beginning of the project:

It may have changed now, on the subsequent prototypes!

how long it takes to get hot?
only 55 grams mass seem light

ToyKeeper, some help on this please :zipper_mouth_face:
Any number given, can only be given regarding the prototypes!

The idea was that Fritz designed it, the mechanics, and the driver (and presumably firmware). He spoke of having done both.

Then Cawi would get it made, with his experience and access to German CNC equipment.

So Cawi cannot hide behind having no technical knowledge. He should be as able to judge any mechanical problems as Fritz.

A small run, at an unknown “Fritz” price, which usually starts at $300 dollars (or Euros).

Then it went commercial and BLF/The Miller was asked to help out, which he did, and set up the contact with Lumintop. And DEL (driver). And TK (firmware). And BLF (publicity and organisation).

But then had to duck out for higher-priority reasons.

Meanwhile the whole mechanical purity has become diluted, nay, bastardised, IMO.

I do hope that it will still happen. Eventually. It might even be marginally reliable.

Well, that’s how I see it, and am prepared to be challenged on any of these historical “facts”.

Meanwhile, TK, DEL and Lumintop, I wish you well.

Perhaps it will all be over by Christmas…

From the beginning…

“A collaboration between TLF (Germany) and BLF (global)
Fritz15 made a small triple flashlight on his lathe.
TLF reacted very positive and at first a small hand made batch would be pursued.
Yet, this elegant design just screams for a wider audience.

For a lot of us mere mortals, seeing the cool things machinists make on their lathe is just a dream.
Hence the finish of the FW3A will be clear anodizing, no sanding/beadblasting before anodization.
The idea is to give all the chance to have a light looking like it came of a lathe with the protection of anodizing.
(surface finish details are still being worked out though)”

Any updates on this the last prototype and when we could see production?

Short answer…. Nope…. :wink:

Count me in - I would like to buy one. Samsung LH351D 4000K 90CRI

Free Beer tomorrow…… :beer: :rage:

I’d like one flashlight please.

I posted a request earlier in this thread but never got a confirmation and I’m not listed on the first page.

Thank you!

At full power? A few seconds. Have you used an Emisar D4? It’s a lot like that.

At a more practical power level? It should run indefinitely at several hundred lumens, depending on how you configure its thermal parameters.

Here’s an output graph from a few months ago, showing thermal ramp-down and then a relatively stable level:

That first minute is likely to ramp down faster than shown in the graph though. It was actually too hot during that first plateau, so I made it adjust down faster.

When started at the default ceiling level of 1100 lumens, the result looked more like this:

This test was 9 months ago though, and things have been updated since then. Mostly, it just shows a rough idea of what to expect when using a high mode which isn’t turbo. I think this test also had a lower temperature limit configured. The stable level depends on the user’s personal configuration and environmental conditions.

The list wasn’t updated yet! Member pepinfaxera will update it later and put your name there too!

The list will not be automatically updated on post#1, only later!!

EDIT: Thanks for the thermal stepdown explanation TK :+1:

I’m in for one . I like little triples .

The thermal response really depends on a lot of different things… so it’s hard to give concrete answers. I think it’ll probably ramp down very quickly on turbo though, in most cases. And at lower levels the response happens later and slower.

It’s largely based on predictions, so the rate of change has a huge effect on how the light reacts. If the temperature is rising very quickly, it’ll make a hard turn downward. But if it’s rising slowly at the same temperature, it’ll only make a gentle turn.

At full turbo though, there’s sort of an override which forces it down to a more sane level as soon as the prediction goes above the ceiling. So, expect it to only do turbo for a few seconds before it drops to the maximum regulated level of ~1100 lm *.

* Lumen numbers are from my cheap uncalibrated light box, and I suspect the real numbers may be a bit lower. I really should order some reference lights from maukka sometime, and build a proper integrating sphere.

It’s only been 3 days. I think the list gets updated every week or maybe every week and a half. No rush.
