Hum, I’ve been thinking about what people are saying here, the desire of a FW4A with 21700 body.
It raises me some questions, and I will present them to help me deciding if I am interested or not in the FW4A with 18650 body, or if I would support the idea of a FW4A with 21700 body.
So, assuming that we will use a 21700 cell/host:
a) would we have more efficiency and more runtime with 4 leds instead of 3 leds?
b) would we have a “lot more” or just a “little more” heat with 4 leds instead of 3?
My questions are honest and are due to some things:
If the efficiency is lower (?), if the runtime is lower (?), if the heat is higher (?) with 4 leds, do I still want a 4 leds head even if the battery is bigger ?
Please help me answering these questions !
Thanks in advance!
Lumintop new HL3A is getting near. Magnetic tail cap, top ss e-switch, Andúril firmware, tri leds, two positions mount reversible clip, served as both a multifunctional L-shape flashlight and a headlamp.

You totally missed out it should/would/could be 25%? (dunno if that’s correct sorry) brighter – quite an important part really.
I’m not at all concerned with efficiency really but I don’t use mine for prolonged stints, and I’m not convinced it would be massively hotter (I am a long way from being expert) but I do have a S41 quad already, and that doesn’t get massively hot, less hot that the FW3A at any rate. I still love it years later.
Maybe if they do the quad they’ll put a copper slug in lol! or, don’t bother with an ally one, just do one like an ally/copper FW3A.

a) Straight mathematically, it will have more runtime with 4 leds 21700 than 3 leds 18650. Efficiency would probably be lower on high levels – probably.
b) I think a little more, 4 leds mean bigger and heavier head and MCPCB, better heat dissipation.
So it is what I think:
Lower efficiency at some point, higher runtime, more heat (but more lumens mean more heat) with 4 leds.

Ahah, no, I didn’t miss that, but that was the “obvious” for me, that the output would increase And, of course, wanting powerful lights as we do, that is something we cannot neglect
But I was more “concerned” about efficiency and runtime in this case and the heat production. Of course, if they do this, they must add, at least, thicker MCPCBs for even better thermal path. Still, it will be hot!!!
Most of these questions are due to my “subscription” for the FW21 (triple with 21700), but also the dilemma between this FW4A and the Emisar D4, that is already a pocket rocket with 4 leds.
So, I will decide what to do and see what the wallet allows me. If a Quad FW21 appears, I will probably get it, but maybe I will skip this FW4A.
Martin, please remove from the “interest” list for now!!
I’ll keep on looking to this, though
BTW, please be warned that the aluminium bezel will probably scratch easier than the SS bezel using the double sided clip and the 18350 tube!! Just saying
a) Straight mathematically, it will have more runtime with 4 leds 21700 than 3 leds 18650. Efficiency would probably be lower on high levels – probably.
Yes, but 21700 × 4 will still give longer runtimes than 21700 × 3? This is the part I am really not sure and want to clarify in my head

Right, better heat dissipation for the higher amount of heat as well! I hope that some extra meausures are taken to manage that extra heat!

Thank you for the pics Kindle! Now that you uploaded them I see that the ones in the first pics show up as well (I suppose Martin has edited the post silently).
On HL3A vs. Fireflies PL47 – the latter is 21700 which is a major reduction of comfort but give much longer runtime.
Despite many similarities I view them as so different that I wouldn’t even call them competitors – though I see that others would. So apparently I would be wrong.
In FW4A – I’m a bit diappointed that it doesn’t use a 22 mm Manker lens. Not that I expected that from Lumintop but with that lens it would be quite a bit smaller and throwier as well. And I agree it deserves 21700….

I would not say competitor to the HL3A vs PL47, but they are similar with their outer appearance, position of driver, LEDs, ….
In the very early development of the FW3A, together with fritz and perhaps only in the TLF I think, was discussed to make it with 21700. But for that the head was too small.
But now with the 4 Emitter head, it must be a 21700 flashlight. And with that it will have the same appearance as the FW3A.
I edited the OP
can everyone see the pictures now?

Interested in HL3A.

Interested both ....
Interested in the H3LA.
Very interested in both, but with preference to FW4A.
HL3A looking good, I’m interested as long as pricing is good and has the same tint options as the FW3A.

I’llskip this obe for sure. Only 21700 is acceptable for quad if you ask me.
instead i got D4V2 Ti.

Interested!
Are there easily accessible pads on the HL3 driver to flash the firmware?
Smile, you cannot kill them all.

I just imagined 18x led, GT size “FW3A” that is just much bigger, but looks exactly the same as FW3A
