If you already have an S42 you can swap the bezel if you desired or even the whole thing, pretty sure the battery tube can be swapped as well.
Sad that would be needed for a new light through.
Got it, thank you 
Probably best not to chance the photo. Sounds interesting, though.
Out of curiosity, if the battery tube on the S43 was changed, would that be the only cosmetic issue most of you have with the light?
I think it might be too late for the S43 to be changed but figure I could give it one last try.
The tailcap striker is already removable, makes the tailcap a bit taller then needed but that is about it.
The bezel is the only other real complaint I see here, how big of a deal is it? it is not that aggressive and is not that bad.
I got permission to post the prototype light I got, these are pictures from Mateminco, the ano looks a lot better on mine in real life then the picture look.
I think it is pretty good looking in the real world, the picture do not do it justice. if I have time I might try to get one of mine.
Hey TA
Is it possible to modify the circuit to get 1A charging or it has to be done through the driver code?
I mainly use 18650 and prefer 1A charging.
He mentioned you have to swap a resistor to boost the charge current.
Yes, there is a resistor that can be swapped to raise the current. No firmware involved as it is completely separate from the main driver.
So what we have here is BLF-modder’s dream-internals (thanks TA ) in a flashlight that is too ugly to buy (thanks Astrolux 
).
Btw, TA, looking at the prototype, did Astrolux ever properly fix the optics issue that was in the S41? So the optic does not damage the leds but still the leds are in proper focus? (in the S41 they fixed one problem by creating the other).
I bought it because it is an ugly flashlight with a great UI - it will take all the bangs and scrapes that I can’t bring myself to have happen to my “pretty” lights
I might get it just for the heck of it. Roll the dice. If I don’t like it, I can always give it away. At the very least it does have a nice UI. It’s probably the only Narsil base light that has built-in charging from the factory.
I don’t know, I’ll keep thinking about it.
Texas_Ace, does the ramping go all the way to Turbo or does it stop short and you have to double click to get Turbo?
I am not sure what the “proper fix” is as I was not ever really aware of the issue but I did not notice any issues with the optics in the prototypes.
The optic has alignment pins for the mcpcb and the optic itself sits on a ledge cut into the head.
It stops short and uses a double click to turbo. Thus far there has been an vast majority approval of this method both from the feedback I have gotten directly and from the manufactures.
Naturally some prefer the ramp go all the way to turbo and there is nothing wrong with that but for Joe public I feel that the ramp stopping short is the better option.
About where does it stop, 1000 lumen?
I modded both my S42 with lexel’s driver…I think that’s still the better way to go. It has better components and better looking of course. I converted one into a triple, and plan on doing the same thing to the other one as well.
Yes, around ~55-60% output generally. Anything less then this and the step up to turbo is virtually un-noticeable like in the first GT.
I like the finger grooves on the battery tube and think it makes the light look better. And I can live with the bezel if that’s what is going to ship. Not that big of a deal to me.
Sadly the BG battery tube is there to stay as they have already been produced it seems.
Are they going to make a stainless steel S43S version of this as the S41S and S42S?
That I do not know, if the S43 sells well I bet they would, with the current looks I am not sure if it will sell good enough for that though.
