Hello Hank,

Do you have nighttime pictures of Noctigon K9.3, where I could see, how the beam looks like for E21A at channel 1?
Also, I was already planning to purchase one more D4V2, but could not see Gray color body option – will it be restocked?

I couldn’t decide whether to get E21A 2000K or 2700K for the K9.3 so i bought one of each. One with deep red on CH2 and the second on with Osram yellow

Also, ETA on cyan D4SV2- kicking myself that I missed it

I have one of those in 6500K but I wish I could get a couple in 2000K. Hank said the emitter isn’t available in this light though.

In fact, when I go to that page there aren’t any drop downs or option to add it to my cart

https://intl-outdoor.com/emisar-d4sv2.html

Yeah, it’s out of stock at the moment completely – I’m hoping when it comes back, the cyan is available again.

Nice! I also have (3) 26350 batteries which are just taking up space right now. I wonder if he’s do a 2700k / 4000k tint mix. Maybe not enough emitters for that to work. I did that with my D18 and the beam looks amazing

Just my unsolicited ¢2 . . .

I’d love to see a: single emitter, triple secondary, 14500 powered, rear switch, tail standing, Andúril flashlight, with a pocket clip – from Hank. I’d be in for a half- dozen of them.

Anybody else?

I’m in for a few.

Yeah me too. Truthfully I’ll buy any new light he comes out with. I have a KR4 in 2000K, a D4VS2, a D18 w/ warm tint mix , and 3 K9.3’s on the way. Haha

I’m hoping he makes a dual channel headlamp. 2000K emitters plus Osram on channel 2 would be pimp

That actually sounds amazing. I’d go 3500k e21a primary though cause I only feel like living in sepia sometimes

Has anyone had any luck getting their KR series tailcap apart? I have a KR4 with a trit button I would like to swap into one of my KR1s (to match colors) but they are both glued tight. Figured I would ask if anyone has tips before I tried. I just use a pair of old tweezers I bent out to grip retaining rings, but I can’t apply a ton of torque that way. I imagine I’ll have to use heat first either way.

Hank now glues the retaining ring in the KR1 / 4 series tailcaps, I have been in discussion with Hank over this. Older tailcaps were not glued.

I crudely fabricated a tool to fit the retaining ring, with one of the recent glued tailcaps and with force alone I am unable to get the retaining ring loose.

On an older tailcap I did mange to loosen the retaining but it took some force.

3500k just feels like the best mix of ‘comfortably warm’ and ‘usable white light’ to me. Anything warmer is a nice sometimes novelty, anything cooler than 4000k to me is a compromise when I’m chasing lumens or candela.

If I was going to get a k9.3 I’d go for a 3×2700, 3×4500, 3×3500 mix to try and pull the overall tint under the BBL. I’ve got a 2700/4500 mix in the KR4 and its my favorite color/tint of all… saying that though the floody optic is fairly limited to indoor/close range stuff. I’m not sure how that would translate to the k9.3 or whether there are different optics depending on the emitter?

Thanks for the information and pics. I want to disassemble the tailcaps on a first-run E21A KR4 and an early-run KR1, I don’t know exactly when Hank made the change but they both seem to be glued. I did try a set of needle nose pliers which fit decently into the rtaining ring, but were unable to budge either one at all despite applying a good amount of force. I guess I will try to heat them with a hair dryer and then try again.

K9.3 Came in today.

Looking forward to reviews of this light with brightness/runtime graphs.

I cant believe it took me a month to try doing this. FW3x deep carry clip fits great on the d4v2 with a little light modification. the new KR4 deep carry clip attachment ring was just a little too big, plus i had an extra one of these. thought i’d share.

Looks like warm light for the switch color, same as what I got in my K9.3. I got the E21A 4500k with SST-20 2700k on CH2.

Nice! Here are the 3 I have coming. Was very tough to decide

1)
Color Black
Switch back light color Red
CH1 (9 inner LEDs) E21A, R9050 Warm White, 2000K
CH2 (3 outer LEDs) SST-20 Deep Red, 660nm
2)
Color Dark Grey
Switch back light color Green
CH1 (9 inner LEDs) E21A, R9080 Warm White, 2700K
CH2 (3 outer LEDs) W1 Yellow (Osram KY CSLNM1.FY)
3)
Color Green
Switch back light color Cyan
CH1 (9 inner LEDs) Neutral White – XP-L HI V2 5D, 4000K
CH2 (3 outer LEDs) SST-20 Deep Red, 660nm

Did a quick comparison shot of some E21A tints. These are all from Hank in different KR4/D4v2 variants. Sorry, don’t have any 2700K or 5000K.

I’d like to see the 2200K come back. I think I prefer it slightly over the 2000K. The difference is subtle though.

Thank you Rayoui. That’s a great way to get a feeling for choosing the right tint. The 2000K / 2200K tints will be great to substitute any real candles in one‘s living room. Just fire up the candle mode in K9.3 and enjoy the cozy atmosphere.

You could do a mix with 3×2000K and a higher CCT. For example with 4500K I get 2269K duv -0.0060 (calculated from independent measurements at 1.25A per LED). In my opinion a negative duv makes warm temperatures look so much better.

Edit : used the wrong measurements, 2506K duv -0.0094 is the right result (makes more sense), so a lower CCT than 4500K should be used, 3500 (~2350K duv -0.0040) or 2700K (~2180K duv -0.0016).

Anyone with a KR1 and is able to kindly measure the reflector for me? Am wondering if it will fit a D1…

That’s certainly an option. I might do this if I decide to pick up another one.

I have an FW3A that I mixed 2700K, 3500K and 5000K LH351D and it resulted in a nice 3600K combined CCT and a beautiful tint. I want to do something similar at some point with a KR4. I just hate messing with the aux board and those tiny wires.

I’d also be up for another run of 2200K. They had great tint, and the difference between 2000K was noticeable. I’d probably buy another K9.3 and KR-4 with those emitters. I also reset the W/B, if you don’t mind to 2200K to show off some of that rosy tint of the 2200K E21A. I believe the 2000K from Hank’s second batch was on/slightly above the BBL while the 2200K was BBL.

That switch is cool looking. What color is that?

I measured 2000K and 4500K a few weeks ago, 2000K was on the BBL : https://imgur.com/a/iP8KoU7

It’s the warm white option on the brass version

I’m a huge fan of the 2000K. My KR4 is sitting on my desk right now, filling my office with soft golden light.
