KD (kaidomain): Deals and new products thread

Olight M2R does 1500 lumens as advertised, but that’s HD not HI. Niwalker BK-FA30S does 2200 lumens as well.

Good to know about the Olight. The Niwalker isn’t surprising - it’s a big 4x18650, and appears to use a 4S arrangement. The multi-cell lights don’t have the same challenges regarding the driver - they don’t have to boost voltage as far, and they have more space to work with. It’s mostly 1x18650 lights (Klarus, Armytek, now Kaidomain, etc.) that seem to have problems.

Nitecore Concept 1 does 1800 lumen (XHP35 HD).

The numbers do make sense though. The XHP35 HI is basically a XP-L HI with a 45% larger die. It produces around that much more lumens and that much more heat. For 2000 lumens you would need three times the power and thus heat of the XP-L HI. Who wants that?

Would be nice to know if this is a flood-to-throw or not.

I would like a non-FtT with a lens

I just sanded a bit.

I got today my first prototype design boards from Schokis driver circuit with a 50W boost chip
I will test it next days, if the massive enhanced thermal connection added to the layout works well, then also some fine tuning the capacitors to get rid of switch on spikes and other stuff needed

I hope production can start end of february

Hi friends

A Korean branded 365nm LED available in KD.

Seoul Viosys UV 365nm Z5 Series CUN66A1B Ultraviolet UV Emitter

Bare LED

with 16mm DTP Copper MCPCB

with 20mm DTP Copper MCPCB

Triple 365nm LED with 20mm DTP Copper MCPCB (Parallel)

Enjoy :smiley:

I am searching for a 10mm XP MCPCB. The only one i can find on the net is the 10mm XP Sinkpad but it is only available at a few shops and only in the US.
So maybe you are interested in selling this size. Many of the small EDC light mods require this size. And i think many people from the EU would be happy to be able to order these MCPCB´s without paying 15$ for shipping from the US.

I thought most optics weren’t transparent to uv? Are the optics you are including with the triple uv led transparent to 365nm light?

Some optics are transparent down to 365nm. Not Carclo, but KD is using their own optic, I think I remember testing it for 365nm transparency and it was pretty good but not close to 100%.

Edit: just checked a KD triple optic again (it came with a triple Nichia 219B board) and the transparency for 365nm light (SST-10) is 50% the most when going through the <2mm top plate, so with the light travelling through the much thicker reflector part I expect considerably less than 50%.
Unless KD uses a different optic for this triple UV board…(my guess: =not likely)

Hi TheOnlyDocc, nice to see you around again, it has been a while. :+1:
I agree, a 10mm DTP 3535 board would be fantastic, I’m out of them for a while and although I’m a fan of VOB, shipping from his shop to Europe is pretty expensive.

Does this LED emit visible wastelight or only purple on the upper spectrum

I ordered one a few weeks ago, should arrive one of these days, then I can tell you. My prediction is that just like all 365nm leds it emits visible stray light, and probably more than the Nichia 365nm leds.

Hi friend

We just get a 12mm DTP 3535 board in stock. Are you interesting in that?

We can PM the details to you.

Thank you

Hi friends

Luminus SST-10 UV365nm LED is available in KD

Bare LED

Thank you


May we know the bin kit order code? At least, give us an idea of the stocks you have.

I would be interested in the 12mm DTP copper mcpcbs for 3535 LEDs, especially if they come at an attractive price for 4, 8, or 12. (for now, I am assuming they won’t be cheaper than a quad 3535 MCPCB, which is one reason why I would want them)

Note: quote was edited to separate image and product link for convenience.

I sort of second L4M4's interest on this host. Zoomie confirmation? Looks neat.

The pill looks like it does not have threads above the emitter deck, where the plastic retaining ring should go. This must be an optical illusion, doesn't it?

I believe amazing spill-free throwers can be made combining convex lenses with specially shaped reflectors tailored for the above lens.

“Fishing Flashlight Host”: is it waterproof?

Cheers :-D

Hey BanL can you get these 12mm boots in clear/white?


They fit the BLF GT e-switch perfectly.
