KD (kaidomain): Deals and new products thread

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.

Luxeon M blue 12V

I wish there was red option available…

I fully agree with you 1stein. BanL, can you please try to source some Osram Ostar Projection Compact LE R Q8WP LEDs? These are very powerful red light LEDs.

Can anyone confirm that this XHP70 N2 5A really has a cri 80+?

Just to be sure you know that is 1st gen 70 right? not 70.2

I know

Thats unfortunate, they used to have the same tint and bin xhp70.2

How’s performance?

I didn’t like it compared to the Carclo … it had a more visibly defined hot spot that had half ring artifacts around the spill… the Carclo has a smoother flood beam (depending on what type of LED used like dome vs de-domed) none to very little defined hot spot, better smoother flood spill the farther out the beam is shown, specially in the bigger heads like the X5, Convoy M1 and Surefire 6P… the Carclo in the FW3A was a smooth flood but gave a square beam profile, because the head is so small…and I had to turn the optic down so much to fit it…Carclo Quads don’t work real well in the FW3 size head…but the flood is smoother…

just my 2cent…

Thanks. :slight_smile:

Does anyone know if the MCPCB it comes with works with both 6V and 12V? I want to use it in the Thrunite T1 which is confirmed to be 12V. There’s no option to choose 6V or 12V on the order page.

Black MCPCB for xhp50/70 is only available in the 6V configuration

Edit.
T1 has a xhp50, which is smaller. How do you intend to use the xhp70 in this flashlight?

Pretty sure it is a standard MCPCB (2S2P, 6V). You need a Sinkpad XHP70 12V/6V MCPCB (upgrade shipping in LEDDNA I advice).

The reflector hole in the T1 fits the XHP70. I prefer buying it presoldered. Will just wait for other emitters to use in this host.

Has anyone used this driver? How bad is the PWM?
CF 17mm 0.9V - 3.3V 4 Groups 2 to 5-Mode Boost Driver Circuit Board

I am looking to rebuild a very old 1xAA light and want to add the ability to use a single 14500 as well.

The other concern is that it is only rated for 3V which would limit use to an AA or 3V lithium primary, not sure it would take a 14500.
