KD (kaidomain): Deals and new products thread

Hi Djozz

Thanks for your interesting with the new driver board.

The PWM frequency is 15000hz.

Thanks

Ban

Hi Giorgoskok

We will update the new product desc asap.

We have re-designed the new reflector for the XP-L HI LED .

Thanks

Ban

Thanks Ban !
Some beamshots would be superb!

Well heck, I am going to have to order another reflector and pill and try the XP-L HI now that it is optimized! I have several of their C8’s, not as clean as Convoy but very functional!

I got the driver in and without having tried it I’m impressed by the number of settings (my favorite low-med-high-without-memory can be chosen, unlike intl-outdoor’s qlite) and by the good connection between batt+ and led+ . The 7135 chips are branded and look the same as Mtn El. uses. Good to hear that the PWM is unvisibly high.
One more question: the manual speaks about thermal protection (output step-down) which is a great feature, but I know that the Attiny13 MCU does not support temperature sensing. This MCU has its branding sanded off, but is it the Attiny25 or the like that does have temperature sensing?

Question - is that “silver” as in the metal?
Wikipedia:

or does it mean silver as in “shiny” (some other kind of plating, such as chrome, or cadmium, that looks “silvery” but stays very shiny without tarnishing?

The nice thing about silver compared to chrome is, silver won’t flake off eventually
The nice thing about silver compared to cadmium is, silver is not toxic
The nice thing about silver electrically is, silver oxide (tarnish) is still an electrically conductive material


Djozz’s question is really more important:

Looking forward to hearing more details when known. The Attiny25, 45, & 85 MCU’s have internal temperature sensors. The 7135’s have an automatic step down when a certain temp is reached (Don’t recall the temp off hand). Guess they could be talking about either.

@KD: I’m interested in this new C8 reflector optimized for XPL HI… Will it be available separately and does it fit other C8 light such as the Convoy and Thorfire?

Thanks for the info, I did not know that (and I do like that!) I agree that may be what the manual refers to.

From the layout, looks like it's not a Atmel MCU - pin #8 appears to be GRND, while the Atmel's have VCC there. Could be PIC based. VCC and GRND is the quick and dirty way of telling if it's an Atmel or not.

Hi djozz

Thanks for you guys interesting with our product.

ImA4Wheelr is right. AMC7135 will step down if the temperature is reached. For the 8 x AMC7135, that mean we have 8 chips to help to so called heat dissipation.

I would check what is the MCU used in KD 7135 Driver board when i back to office on tomorrow.

Thanks

Ban

The web page says:

What product should be used there?

Hello Ban .
I saw today that the new C8 was listed. As Will asked , when will we be able to buy the new reflector separately?
Thanks

The two redesigned KDLIGHT C8’s XPL HI V2(Neutral) or V3 (Cool) with the new V3 driver at $18.99.

So psyched to see that light available. Might have to grab a neutral.

The new P60 drop-ins with 4500K Nichia 219B’s and 1.5A driver look great. I have made similar drop-ins, but this is a great option. Perfect for anyone with some underused P60 hosts lying around. A great tint and beam with long runtime from a decent 18650.

@Rolz - KD has also got a couple of KD C8 XPL-HI V3 1600 lum 6500K with Orange Peel (OP) instead of the SMO

I wonder what the OP reflector does to the both throw and spill and how much different would these be to the KDLIGHTs you mention?

The model I have to review has a smooth reflector which helps with throw. If I get an opportunity to gram an OP version to test out I’ll pass on the beam shots and results.

Still looking for your C8? lol the OP will make the beam less of a thrower and it will also give it a warmer appearance I build a C8 with a OP textured reflector like these ones its nice it still throws far but no where near as much as a standard C8 as for power @ 3 amps these will maybe just 1000 lumen nothing spectacular same package as what convoy is offering but it appears that these lights have no centering ring the reflector is custom made to sit on the MCPB i cant tell for sure because no one has to taken pics. Other thing is the driver looks like it is soldered in and doesn’t use a retaining ring…

@Every
Yes still looking for a thrower C8 for the boys (’I’ve got a stock SMO Thorfire C8S)
Just considering my options mate

@Rolz
A review of the OP C8 would be great especially for someone new like me
