KD (kaidomain): Deals and new products thread

Looks like a nice regulated driver! But a steel spring… really?

Nice! Interesting selection of modes here, and the longer spring is a nice addition:

Hi Mattlward,

This is not Steel Spring. This spring is brass material with silver coated.

The spring wire size is 0.7mm.

Thanks

Last night I ordered one of the KDlight V3 8x7135 drivers. I like the added reverse polarity protection and how it deals with low voltage. The mode spacing is good and unlike the Qlite you can choose for no memory, which is essential for me.

BanL, do you happen to know what the PWM frequency is (too high to notice I understand but how high?)

If it works as it sounds, it is going to serve in a mellow XP-G3 high CRI triple build. :slight_smile:

Hey BanL, thanks for the reply… Guess I will need to order a couple! The specs look great, I like regulated drivers in many of my EDC lights.

Which is the new KDlight?

Also will you get more cheap C8 hosts ? (like the old with red leds , they were great hosts).

I really like the KD C8’s as well, good selection of parts for them as well.

They have a 5-mode XM-L T6 C8 for $10 on clearance (bottom of the home page)

Hi Djozz

Thanks for your interesting with the new driver board.

The PWM frequency is 15000hz.

Thanks

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
