KD (kaidomain): Deals and new products thread

Hi guys

Thanks for your interesting with KD C8.

There are many different C8 products in the market. As you know, C8 has a very long history. It has many different variation, generation. For the KD C8, it is a standard C8 version.

I will list the measurement for this pill. You can know more that it is supporting to your own C8 or not.

Overall Pill Dimension: 26mm(Dia.) x 13.5mm(Height)

Upper Part:
Outer Part: 26mm(Dia.)
Inner Part: 21mm(Dia.)

Bottom Part:
Outer Part: 19.5mm(Dia.)
Inner Part: 17mm(Dia.)

Thread Spacing: 22mm x 1mm

This pill is better used with the Lens with 2mm thickness.

If you have any question, please feel free to contact me.

Best Regards

Ban

djozz,

Thanks for the heads up on fitting the UF-T20.
Just got done doing the swap, retaining ring on the lens was a bear to get loose but after that it was easy.
I left the shorter spring on the KD drop in intact, now the light will accept longer batteries without a fuss and still runs shorter unprotected cells as well.
Now it is bright, great tint and no rings, Got me a new Pocket Rocket:)
What do estimate the throw/lux to be after this swap?

My UF-T20 with dedomed XP-G2 R4 (yes, that was a long time ago), did 108kcd (at 2.95A). The newest bin is S4, which is 26% brighter, so that would throw 136 kcd. The XP-L Hi has a die size 2.2 times bigger, with the same current and output the throw could be 62kcd. But bigger dies project relatively well in aspherics (the poor lens quality is more forgiving towards them), and the bigger die XP-L has a bit better output at 3amps and thermal management, so a rough guess could be 80kcd.

But reality could be very different…

New Big reflector is arrival

86.2mm(D) x 84.7mm(H) OP Aluminum Reflector

US$18.65

Nice, an OP version.

I may have to pick one up to drop into my modded L3, & change over to XHP + FET…

Another Cree XHP35 HI is arrived to KD

Cree XHP35 HI D4 1A White 6500K LED Emitter

Cree XHP35 HI E2 3C Neutral White 5000K LED Emitter

And there is some solder on base plate. You can take a look on these.

Thanks

Looks interesting. Will be great to see some flashlights based on these LEDs. A 3 x LED model with Multiple batteries may be the answer here as the forward voltage is high.

Looks like a great driver with lots of options. Thanks!

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
