I had forgot all about TK’s Tom Tom post, I was back focused on the light again. Then Tom brings it up and now it’s topical again. I think he shot hiself in the foot by bringing it up.
Now back to the FW3A.

OK! So, what mods are you people thinking about when the FW3A arrives?
Not planning on modding. The only exception being a possible LED change in one (1) of mine. The stock XP-L HI’s will remain in the others.
I’ve been thinking on that too, I would like to get some Luxeon V 4000K into it!
Recently, I started thinking about the possibility to add a tritium vial in the tail cap, but that may be dependent on the thickness of the metal (to dig a place for the trit)
I would have liked some LH351*B* but they don’t like direct drive…
So it’ll be SST20, maybe I’ll try a 3000K + 4000K + 5000K mix to see how it goes.
Maybe Orange LEDs if it’s there for Halloween

"-X3-, is there any place in your house without a flashlight ?"
OK! So, what mods are you people thinking about when the FW3A arrives?
I’ll configure Anduril to discrete ramping, floor level 1, ceiling level 130 (max 8 × 7135), and 7 steps. This puts max 1 × 7135 at step 4.
I’ve been using discrete ramping with my ROT66 and I think I prefer it this way. Of course, if I need more options, it only takes three clicks to go back to smooth ramping.
If I have the free time, I’ll do a 3-way comparison to decide what emitter choice I like best:
The ease of modding will depend on whether Lumintop glue it together, as was their intention.
Please not, at least for the BLF run.
Has that been kiboshed yet ?
Lower Vf leds don’t concern me, actually my preference for overall efficiency and consistency of output, in linear mode. This has X1 and X7 7135 banks (I think), which is enough to sustain more than enough output for my needs, and as much as something this size can reasonably sustain, thermally.
Actually this driver (DEL’s ISTR) is a key attraction, together with the lack of bling stuff (e.g lighted up this that and the other).
I see the FET as a novelty feature, of little practical use, for me, for a few seconds. But fun.
As a compact, factory triple, with an attractive driver and firmware, at a price which I would exceed just trying to cobble together e.g. an S2 myself, I still want one.
The tail e-switch keeps it short, but adds a lot of complexity and potential for future problems. Time will tell. At least it is in the right place, tail, not side. It also makes it interesting.
Efficiency is in opposition to consistency of output with linear drivers. That is to say, consistency of output is provided by lower Vf, but using a linear driver with a large difference between LED Vf and battery voltage results in more energy wasted by the driver.

Not really. Keep in mind that they were only considering using glue on the tail cap. So the only mods it might effect are removing the clip and bypassing/replacing the tail spring.
All the more likely mods, swapping emmiters, lenses, etc… are not effected.

How much of an effect does bypassing the tail spring actually have? I know PFlexPRO swears by it (claiming “200 lumens” worth of reduced resistance), but if it was actually such a major difference maker, wouldn’t it be more of a standard feature rather than something only seen in mods?

It does make such a difference but more light is not always a good thing for a responsible manufacturer:
Often bypassing springs is done in flashlights with already high current/output in which case a bypass will add light in an inefficient region of the output curve of the led, so the bit of extra light comes with disproportional shorter runtime and lots of extra heat. This may be worth it for a flashoholic but in general it is a bad idea.
If there is any light around in which bypassing springs could cause more trouble than is worth the extra light, it is the tiny FW3A.

I mean, wouldn’t you pair the more efficient wiring with a lower output driver and/or scaled back regulation?
Yes, it might not play nice if you add it to something that is not designed for it, but if a responsible manufacturer is designing from the start with that more efficient path in mind, that would be part of their calculations.

Didn’t mean it necessarily in the context of this light specifically. The mention of it just reminded me of my curiosity about it in general.

Yes of course, that would be marvellous in case of that illusive 17mm one-sided slim buck/boost driver, but the plain reality is that many (most) single li-ion battery flashlights are driven by simple lineair drivers, so for a given current, regulated or not, over-voltage will simply be burnt off somewhere, if not in the springs then the driver will have to take care of that. In the special case of a unregulated FET-driver, which the FW3A is at its highest modes, the already very high current will just go further up.
if it was actually such a major difference maker, wouldn’t it be more of a standard feature rather than something only seen in mods?
Part of the reason you don’t see it from the factory much is that it has to be done by hand, not by machine, so that adds time. It also has to be done properly which requires real technique. The average assembly worker has no time to learn nor does the company want to slow down the assembly line by doing it.
If not done properly, it can come loose and cause a short circuit and fry the battery. (Think of Haikelite MT09R bypass wires on the outside of the spring) So there are these legitimate safety concerns.
Add it all up and that’s why you don’t see it very often.
Double low resistance springs are something that is much better for a factory light and it seems it’s catching on. Especially as lights get brighter and currents get higher.
The FW3A is not meant to be a hot rod. It’s turbo is more “practical”.
