I can vouch for Intl-Outdoor, placed many orders and never had a problem.
It’s Hanks own store so fully legit and you will be looked after.

Looks very nice, but a little pricey.

Just ordered from Hank, with Warm White – SST20 3000K 95CRI. This will be my nightstand flickering Candle light. Thank you ToyKeeper for this awesome UI.

I’m not sure if there are any diffusers which fit, but ceiling-bouncing it can be nice sometimes too.

However, tail-switch lights in general are a little awkward while ceiling-bounced. The button isn’t accessible in that arrangement. So for a bedside light I usually go for something with a side switch instead.

Diffuser added to fw4a package shall fit. I think this is the same as the one for fw21a that can be found on aliexpress.

TK, yes… it will be ceiling bounce in candle mode. I can see the utility of the side switch for tail standing, but I’m ok with the tail switch – no problem picking it up to adjust.

Thank you. I will have a look for that.

FW4A diffuser will fit the KR4?

Yes. If you take a look at head diameter fw4a is 28.5mm vs 29mm of kr4.

I can’t seem to find the EA21 LED option for KR4 in Intl-Outdoor’s website, is it a limited edition only?

https://intl-outdoor.com/noctigon-kr4-quad-tail-e-switch-edc-led-flashli...

Or maybe need to contact Hank about the EA21 LED option (with additional charge)?

Any idea when the E21 emitter version will be available for sale? If it’s going to be soonish, will wait and get both the K1 SBT90.2 and KR4 E21 at the same time.

Also, on the intl-outdoor site’s search bar if you type in D1S, there’s an interesting suggested autocomplete for “37D1S v2”. Sure would like to see that come out soon.

Our E21A LED package is stuck on the way for long time due to the virus issue, not sure when it will move, so, we are not sure when it can be offered. The 10623 optic will be default optic for the KR4 E21A version.

Hank said this early in the thread.

Mr. Maukka, thank you for very detail review with lot of information!

Do you think e21a is your favourite led? How does it compare with sst20 95cri?

The kr4 driver looks different from normal driver, do you know if it is similar to loneoceans gxf22 driver? http://budgetlightforum.com/node/67820 I don’t think I saw it in any other flashlight yet. It will be nice for kr4 to have fet mode as well, but maybe not for e21 version.

I’ve had this one in cyan for a month or so, very happy with it!

The KR4 driver is a separate design not by me. However, the KR4 looks like a really nice product and I'd love to have a go at making a driver for it..

Personally, I do quite like the Noctigon line of products. They seem to be well designed with good quality manufacturing and assembly, together with good product support. Thanks Maukka for your detailed review.

I personally find Emisar/Noctigon design quite nice. Hank lights combine practicality with appealing look. I think that the only thing that I don’t like in Emisars is glue. In my expirience glued driver will be most likely destroyed during disassembley attempt.

My KR4 with SST-20 3000k CRI 95 arrived yesterday.

What an awesome light. I absolutely LOVE the wide/soft floody beam and the 3000k tint 95 CRI is gorgeous – exactly what I want for an around the house light!

I added it to my flickering LED candles in the bedroom last night, with the KR4 doing a ceiling bounce in Candlelight mode – the warm flickering light matched the flickering LED candles beautifully – creating an awesome romantic ambience.

I like the light and the output of the four SST-20 3000k emitters so much that I just ordered a D4v2 and D4Sv2, both with SST-20 3000k 95 CRI lights from Hank.

These are easily my favorite around the house lights now. Hank Wang .... your lights absolutely ROCK! And same for you ToyKeeper with your Anduril creation. Thank you both.

I just checked the KR4 E21A store page and in the description there it says that it comes with a Carclo 10623. This would adress maukka's initial criticism concerning the 10622 clear optic.

Can anyone confirm that it's delivered with the frosted 10623 now? cool

 

edit: Nevermind, Hank confirmed it over here.

Is there any timeframe announced for the mule version of KR4 with E21A, already?

I’m considering a KR4, interested in the E21A emitter as well.

Just wanted to share the happy news, that the KR4 E21A is now available in 2000K and 2700K.

I’m eager to try something with quality 2000K emitters. I was mostly a 5000K person until I tried some CRI 90+ 3000K lights and was kind of blown away.

Thanks Maukka for this – once more – amazing review.

The Noctigon KR4 is also available with a Nichia 219C (4000K, 90CRI). Any idea of how it compares with the E21A?

Ultrafire C3 2AA / Nitecore LR10 / Manker E03H / Fenix HL10 / Zebralight H501R + H51W / DQG Hobi / Astrolux M01 / CooYoo Quantum Ti (lost) / BlackWater Kite Al

Only with E21A does the Noctigon KR4 come with the driver with no PWM, at least that is how I interpreted Maukka’s review.

…the E21A version is based on a noFET version of the Anduril firmware, so the output is lower, but the tint and color rendering should be better.


Combined with a new type of constant current FET driver similar to led4power’s offerings, the KR4 aims to improve on the efficiency of the traditional 7135+FET driver especially on higher outputs. On the E21A version the driver offers regulation up to 5 amps with only the temperature being the limiting factor.

Maybe a little ambiguous. I am not sure why with E21A the KR4 would have noPWM and the other emitters would have PWM with a different FET driver altogether, but that’s how I read it.

The KR4 and D4v2.5 (CC driver installed by request) using XP-L HI/SST-20/etc. only have PWM between 5A/max CC and turbo.

The E21A versions have the FET disabled although it may be physically present on the driver itself, and do not use any PWM. The type and/or wiring of that FET on the 3535 LED versions is different from previous Emisar/Noctigon lights and other common 7135+FET designs.
