Have you looked at Shockli and Vapcell’s crazy top of the line 1000mah high current cells? Those are real beasts!!! They can push harder than NCR18650GA. It’s been my dream to have a 14500 light that can actually take advantage of these two cells. The FWAA can utilize the power of this but it has other problems.
Anduril 2 and you can request by email if you want 1.
It’s not just the cell—a tiny 1aa light isn’t going to have much thermal mass, so it can’t run at high power for long. Also, a 1000mah cell would get used up awfully quickly at such high drain. Even the 18650 in the D4v2 gets drained pretty fast, which is why the 26500-powered D4Sv2 exists.
I love this idea. I have employed it in my flashlight design projects. A simple integrated charging circuit that threads on in-between the head and body tube, with a USB-C port on it just like K1. Except it’s optional and removable.
^ that’s very neat idea.
Not everyone likes internal charging but also not everyone dislike it.
I’m really looking forward to this, Hank. Any idea when it will be available?
Hi Hank,
Would you kindly share what battery it’s using (18650, 21700. 26650 or possibly all three?
Thank you.
Oh man, that’s massive :/
Not what i had in mind when you said “smaller thrower”.
How does it look like next to KR1?
BLF GT Micro in brass mine holds turbo for a bit over 1 minute,even down to lower voltage levels.
He’s said previously that it’s using 21700. That also means an 18650 will fit, but may need a spacer to make contact and not rattle.
Yeah I would have hoped for something like a Zebralight SC700, which is possible to make a with classic construction (i.e. not the LED on driver board, not unibody), since a TIR is shorter than a reflector, at worst by adding 5mm, making it as long as the KR1, and around the same thickness despite the 21700 cell (no signal tube).
Yes! My thoughts exactly.
I think the KR1 fits exactly between this DM11 and the KR4. Looks like a nice size to hold, considering how the slightly smaller KR1 is comfortable yet a little small in a side-switch grip (in my medium hands).
I like the classy but brutalist design. I think I will make this my first 3500k light with the classy nichia emitter.
Thanks for the picture, Hank.
Very nice flashlight except for maybe the knurling, seems a bit too aggressive for such a relatively small light.
Is there any particular reason why you designed it that way?
I agree, knurling is too much.
Isn’t the SC700 a flooder though? (It can sustain 1,400 lumens as well which is very impressive for the size).
It is definitely more flood than throw. Has better throw than the Thrunite T2 but that isn’t saying a ton. Anyway, I would totally buy a sc700d model with a TIR optic. It’d be sweet.
I suspect a lot of people are doing what almost always happens to me when I look at a flashlight picture, and perceiving it as bigger than it really is. Keep in mind how compact a D4v2 in the photo is.
That said, it had to be at least very close to the size it is for the features it has. I’ll repeat the math I posted over on the flashlight reddit:
Hank already mentioned he chose a 40mm head. It will get a little more throw than what a 35mm head like the KR1 and original D1 had - that’s a pretty straightforward tradeoff that some will prefer, and some won’t.
For length, consider our D4 again as the starting point:
95mm
- 5mm to go from 18650 to 21700
- 18mm (my estimate after looking) to go from Carlco 10mm quad to 35+mm single TIR
- 2mm to allow for the height of the inductor for a boost driver
==
120mm
To double-check that - the K9.3 is 124mm long. A quick scaling check on the photo puts the new light at 4-5mm shorter.
It doesn’t seem like this light can get much smaller without trading a little bit of throw (smaller optic) or battery capacity.
To reduce the weight and enhance the grip, it’s much more hard to machine
than the shallow knurling.
