KD (kaidomain): Deals and new products thread

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.

Seems the MCPCB is garbage with too wide holes

Another 1-2mm on slightly thicker legs should fix the quad optic, just enough to sit proud of the domes and adjustable with light sanding.

I think it’s the same 2 legged quad optic used on the S41/S41S

. I remember changing a bunch of them S41/S41S into triples because the optic sat on the LED pad and crushed the pad. Also when you tightened or removed the bezel you broke off one or both legs and sheared the domes off…sumtin like that…IIRC…

. ENEDED

. I have a bunch of them in the junk box I pulled out from the ones I changed out…

. I used one in a FW3A (had to add a copper shim for the height to delete the glass lens) to compare to the 10621 Carclo beam…

So what you are saying is after 3 years no lessons have been learned. :person_facepalming:

:wink:

Looks like most Luminus LEDs are on sale.
Very good price on SST-10 UV.
$5.69 for bare emmiter (56% off).

Could you load the beamshots KB?

I guess the “return” section of the website is just for show. I submitted one over 2 weeks ago but no contact or further instructions.

No acknowledgement in this thread of the issues either. Can’t say i’m surprised based on past posts but in the future I will refrain from ordering new products and let other people be Kaidomain testers.

Hi contactcr

Are you meaning you had create a product return request in our system?

You can let me know what is your returning tracking number.

I can track where is the package.

Thank you

Ban

It doesn’t even say to send it back much less where to send it. I don’t see an address listed anywhere on your entire site and no one has contacted me so I don’t know why you are thinking I would have shipped this back for more than I paid.

Return #289 and #290

If the products don’t fit together you should remove them and take it up with your mfg. I’m not shipping unsellable product back.

Feel free to correct me if these products are good and let me know how they are supposed to be used.

We are using Quad PCB and Quad LENs to install on our LED drop-in module.

Please let me know how you use on the Quad PCB.

Please note that those are DIY component for your DIY application.

You need to make sure the dimension is correct for your application.

If our listing parameter is wrong, this is our fault.

We are not making any component that is suitable for specific branded flashlight. If we do so, the title that we use is for xxxxxxxxxx.

This is the aims of DIY.

Hope you can understand with it.

I get your message on our system.

“The holes in the MCPCB are too big and cause the optic to sit too far down on the MCPCB. It will crush the LEDs if you tighten it down”

The bigger holes on the PCB: We have plastic screw to stable the PCB and mount on the quad drop-in pillar.

The smaller holes on the PCB: It is just for LENs ’s leg and avoid to move.

I don’t know how you use with Quad PCB and Quad Lens.

And you mention that is the LENs will crush if you tighten it down.

So what is the height of your flashlight’s head.

If it is too tight, will you consider to sand the LEN’s hole?

The hole in the lens is fine. The dome of LED fits as it should. The lens is going to rest on the base of the LED and crush it there. It does not need to go around the whole LED including base/substrate.

Did you try to put your module in a light with the lens and bezel tight?

@BanL - the problem is the legs on the optic just need to be a mm or so longer.

The optic is what it is, probably off the shelf part? The MCPCB is what KD specced out and the holes are too wide so it drops in too far.

A previous version of this optic/board combination from KD (I have one) had a thinner 1mm thick MCPCB which was also not good: the holes were either too wide or the optic needed a bit sanded off the legs. I never bothered to find out what exactly was wrong because I never used it, but it clearly did not work off the shelf, something had to be fixed.
