Hmm…
That would indicate a problem on the line China-EU… But I’m not an IT guy to figure it out properly…

Yep, working again.
Last time it was the same: a short warning off, then off for a few days.
Hope it’ll stay alive this time.

Thanks for all your feedback.

Any chance of high cri neutral white nichia leds ? (219C 319AT 5000K)

Hello Ban,

Could you please get some of these LEDs below?

https://download.luminus.com/datasheets/Luminus_SST-10-DR_Datasheet.pdf

https://download.luminus.com/datasheets/Luminus_SST-10-FR_Datasheet.pdf

(B130 variants, please)

Now, these are the best deep and far red LEDs from Luminus (better than Cree equivalent), and you already have a recent driver for low Vf red LEDs with 1 or 1.4A current, which is a good match for these.

These LEDs also have (as I saw) the same MCPCB solder footprint, as the Osram KW CSLNM1.TG, so you could also sell them pre-soldered, with the recent 3030 MCPCBs already available.

So how does one get support from KD about problems?

They don’t respond to emails.

I received a bad driver from them. I sent a message through the site and never got a response. Probably not worth the hassle for a $3.50 part.

User e1000 reported a downgrade for the H1-A driver, Nightsword confirmed it. What will happen now on high with modified drivers? Bad, very bad.

I see the H1-A is now “on sale” (can't use coupon then), with an old photograph it doesn't abides by. Most users here prefer quality over cut corners. Cut corners may end up costing us money.

Incorrect way of believing. Every bit of your money is worth it. If you don't care, parasites will leech you to @#$%.

Or buy via Aliexpress who have their own policies. You pay a bit more but in the event something goes wrong you have an escalation pathway.

I did not notice that before. KD claims the fcbB46 bin of the PM1 which is indeed the warmest Chromaticity Coordinate Group that is in the datasheet.

Which Color is sold by neven? I have some of these emitters but they are way too cold.

Is it right that KD sells 2C and Neven 1D, translated to the Cree Color Shema?

The fcbB46 is the warmest bin ranging from 5300K to 5800K but the duv is also above the BBL unfortunately according to the chromacity coordinates for this bin in the data sheet.

You can plug in the 4 corners of the tint quadrant into this link to see the CCT range for this bin.

It could still be below the BBL as we all know the actual emitter and bin labeling can be quite off sometimes.

When overdriven these things are never near the binned chromacity

Voltage and flux bins are the same as that from L4P.

LEFT: FW3A MCPCB + 10511

RIGHT: Kaidomain Quad Optic and MCPCB

I’m no expert but I don’t think this is right. It seems this optic sits too far down into the MCPCB since either the optic legs don’t have a big enough “shelf” and/or the MCPCB holes are slightly too big.

Sitting on the flat granite I can slightly rock the optic back and forth by the two optic legs but just barely. It’s basically just a thin sheet of paper shy of straight up resting on the MCPCB. In two of the MCPCB holes there is almost no rotational play so it probably wont shear a dome but I feel like it has a decent chance of crushing the substrate or not being in the correct focus?

MCPCB is 1.6mm high (listed as 1.5mm) so that probably doesn’t help either

Had the exact same problem, the optic rests on the dome meaning that the optic cuts into the domes when it’s installed with any pressure on the optic. Lost 4x XP-L HI’s finding this out.

RIP, sorry for your loss. I probably would have done the same if I wasn’t trying to dry fit it inside a FW3A to see how close it is.

I feel like I frequently pay the early adopter tax when it comes to this hobby :\

I damaged a LED from the triple because of the presure too Facepalm

The triples don’t seem bad, but then I use the Carclo optics with those.

The KD quad optic simply has a design flaw or isn’t suitable for use in flashlights.

I hope KD will acknowledge this and address it.

I have built a few triples with Kaidomain optics and i always shave the legs so the optics sits flat on the MCPCB? The triples are deep enough to fit over the whole LED?

If you already have the optics over the dome and its done no damage there should be no problem? you can only apply a very limited amount of pressure more once tighten.

I tried the Kaidomain optics at the stock height looks similiar to your left pic and the beam is wrong its all wonky.

On the domed LED’s its still resting on the LED itself and the pressure will cut into the domes around the bulge. On the XP-L HI’s it just sliced the phosphor off the package.

Weird maybe the quad is a different optic to the triple, Hopefully Ban can fix this problem.

Lets not clutter up the issue with triples. It’s a different beast and he has already revised his triple boards at least once.

In any case, the optic will fit around the dome fine but not around the entire substrate.
