KC1 keychain light is available now

There is one on Vinh’s site.

I have a D4SV2 on hold pending the emitter choice, I have them in XP-Hi V3 3A and SST20 but may try something different for my green version. Would be interesting to see the W2.

So I put a xhp50.2 in my Cu KR1 the other day. Let me just say, it’s an awesome all around edc. Copper is heavy but I like it, xhp50.2 has tint shift, but I don’t care especially outside. I know Hank prob doesn’t use the xhp50.2 because of lack of tint options and tint shift hence a not really attractive beam, or maybe there other reasons, but I’m putting a pic here for others who may be interested in doing it themselves.

Xhp50 on left, w2 on right. Both kr1.

Visually, it’s brighter and throws almost as far as my ft03 mini with xhp50.2. Also the tint shift is not nearly as bad in real life as it is in this picture, especially outside.

Thanks, completely missed that last photo :blush:

The D18 deep red and 2700k custom swirl ended up being pretty great. Pardon the terrible quality, it’s way cooler looking in person.

Wait… Does it mean that D18 has 2 separate channels?

No. As it turns out, deep red and “regular SST-20 have different-enough vf that the deep red come on solo first, followed by the 2700k higher up in the ramp.

Awesome! I used to believe that this would fry leds with lower forward current.

We will see.

The deep red come on solo at moonlight and don’t appear to be overdriven, based on also observing their behavior my DR-only D18.

I’ll have do some research because now I’m curious, and I’m currently ignorant of all the factors here.

That d18 red swirl is amazing!

Thanks, I agree! Keep in mind it’s not for everyone with the non-red emitters only coming on at the higher outputs. Still completely worth it to me.

Do you guys think Hank will ever re-stock the 2200K E21A?

Does anyone know if and when will the mule versions be available again?

Email hank if you want mule versions.

I recently got a brass 4DV2 with 16 E21A 2000k and I love it but it behaves weird in Party Mode. Just wanted to see if others have observed similar. It flashes randomly at low to medium brightness, completely different to how my SST-20 lights behave. At first it looked like Lightning Storm to me… All the other blinkies work normally!

Any ideas why that would be?

Can you check the Anduril version of your D4v2 with E21A?

I tried flashing the D4v2.5-NoFET-2020-07-08 (Anduril 1) hex file on my D4v2 with 4x E21A, which resulted in party strobe mode that’s very dim (yup, like a very dim ‘lightning storm’ mode).
I then flashed it to anduril.2020-04-27.noctigon-kr4-nofet (Anduril 1) hex file, and party strobe mode works normally.

I’ve subsequently updated it to Anduril 2 (2020-09-27-KR4-NoFET) and party strobe mode also works normally.
(there is a newer Anduril 2 version now, which I haven’t tried).

I’m not sure if the 16x E21A will work properly with the above hex files though (since mine is the regular 4x E21A)…

Thanks d_t_a!
It has the version from 2020-07-08, so that’s the issue. Not that I really care to fix it, don’t have a flash kit and no real use for that strobe.

On another note, I know that the mules use a 7.5A driver, is that done in software or is it using different hardware?

The KR4 driver has trouble with the fast switching on that strobe mode. There is a config flag that changes the timing, but it appears to have been left off some builds.

In the Anduril 2 repository, this is around line 48 of cfg-noctigon-kr4-nofet.h:
// slow down party strobe; this driver can’t pulse for 1ms or less
// (only needed on no-FET build)
#define PARTY_STROBE_ONTIME 2

Although the comment says it’s only needed on the no-FET build, I’ve found it to be needed on my other KR4’s, too.

What is the weight of copper D4v2 with 18650 & 18350 tube (vs aluminium version)?

Here you can find the weight with the 18650 tube, I can weight it with the 18350 tube tomorrow.
