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.

Agreed, I wouldn’t do it with this light.

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.

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”.

I had a a slight feeling when I wrote that it would return to bite me in the arse…. FacepalmBig Smile

My definition of “soon” as it relates to the FW3A. ……
….. “It will happen within 2.25 months, which is 10% of the previous 22.5 months since the FW3A was Officially announced; 4 May 2017… the day of the OP.”

That’s my story & I’m sticking to it…. . Wink . Big Smile . Big Smile
.
.

soon /so͞on/adverb

  • 1. in or after a short time: “everyone will soon know the truth”
    synonyms: in a short time, shortly, presently, in the near future, before long, … more
  • 2. used to indicate one’s preference in a particular matter:
    “I’d just as soon Tim did it” , “I ‘hope’ it happens soon”.

I’ll take 2.25 months, sounds reasonable to me.

Smile . Thumbs Up .. Me to at this point. It’s but a fraction of the total. If it really does happen in the 2.25 months that is…. Wink

Currently the XPL-HI in 3D (roughly 5000K) and SST-20 4000K.

Oh that’s great. I just got a d4 with the sst-20 4000k, and really enjoy it. Does anyone know why it is difficult to get ahold of the LH351D? Is it a demand issue? Just curious.

I believe this is not entirely true!
As said here by Toykeeper :

[…]The supplier has been unable to get LH351D yet, so the first run is almost certainly going to be XP-L HI 3D only. After that, I’m not sure if it’ll be SST-20, LH351D, or other XP-L HI tints.

One thing is to talk about the emitter, another is to already have it as an option!

No problem, it is hard to keep track of all the relevant info after a while! Still, it is better to mention post #1 for the last updated information. Many things said in the middle are wishful thinking and our desires, what may be confuse. So, it is better to check post #1 or the posts from Toykeeper and tatasal that have been providing the last updates Beer
