Review: Noctigon KR4 (18650, 4xE21A 5000K, CRI96)

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.

Thank you!

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

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

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? GXF22 - Very Low Resistance FET & Constant Current Driver with Fuzzy Logic + Microphone 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!

i just received this in an 8LED mule configuration, and it is fantastic.

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.

KR4 E21A version available,

Interesting.

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?

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.
