KD (kaidomain): Deals and new products thread

I hope that KD can get the new XP-L2-W2 LEDĀ“s until the BLF Q8 is ready to be sold.
This will be a lot of work and also not realy cheap but well worth. The Q8 + 4 new XP-L2-W2, a new XHP50.2 as upgrade for my modded TN31 (K40M driver with resistor mod and dedomed MT-G2 LED and i added a lot of copper to help with the extra heat), and a XP-L2-W2 upgrade for my UF-1504.

I have one question. I bought a few Cree MC-E RGBW LEDĀ“s. Now i need the MCPCBs.
Is this the right one for the LED?

http://www.kaidomain.com/p/S006044.21mm-Parallel-Star-for-CREE-MC-E-5PCS

Yes those would work

And donā€™t go over 700mA per die, that is really close to the max already.

I want to use 5 MC-E LedĀ“s for the Lamp. It will be a Lamp for the living room. The ledĀ“s are pointing towards the ceiling. I want to use Aluminium profile 40*40mm and 50-60cm long.
Then a remote controller like this (Page Not Found - Aliexpress.com) which is controlling 4 of this drivers (http://www.ebay.de/itm/1-Stueck-1000mA-KSQ-8-32V-Input-0-30V-Output-dimmbar-/351975399530?orig_cvip=true).
And each driver controlls one color. Powersupply is 24V DC. And finally i have to find a optic with a really wide spot.

@djozz would it be better to reduce the current to 500-600mA/die? If all dies get 700mA the LED gets a total of 2,8A. I think that this could get really warm without extra effort regarding cooling.

I love your project! Very nice:)

The full 1a per die may be a bit much if all are on at the same time. But then again, if it were me I would find a way to use the full power :wink: Can you add some cooling fins or added heatsink to your aluminum profile?

Edit: Actually I see that 700ma is the max rated current for these dies. I donā€™t think I would top that especially without a direct path mcpcb.

Any opinions on this new (?) driver for 6V leds? http://kaidomain.com/p/S026606.H1-A-20mm-3A-1-cell-5-Mode-Boost-Driver-Circuit-Board-for-Cree-XHP50-6V-MT-G2-MK-R2

Can it work with an e-switch? It would be nice in a Skillhunt H03 :slight_smile:

Finges I am currently working on a Narsil FET+7+1*7135 driver set up with thermal management

If the Narsil works out great I will have a spare H03 driver
The H03 one has too high voltage drops as the current has to go through the inductor and a small transistor
@3A the losses on the Skilhunt driver are 410mV, so a fresh 18650Q cell can reach 3A only with both springs bypassed for a short amount of time

And I dont like the timed stepdown
The UI is OK

An Attiny13A 7135*8 driver with eswitch firmware is also an option, but not priorized atm

You could get a XHP50 with boost driver in there, but I see thermal issues.

Does the H03 have a step down driver?
Does it work on 6 Volts too, or even 8.4 Volts?

No the driver I linked is for 1s only

It boosts the voltage from 1 cell to power 6V emitters like XHP50, MT-G2 etc.

The H03 has a stepdown driver up to 8.4V

I have never ordered from them... Just found some tail switches I need badly and signed up ready to place my order and it says account not activated...

Anybody know a US vendor with 12mm*8mm*8mm for sk68's. Ordering from anywhere else just ain't working tonight for some reason.

Send them a email they have problems with the register system atm.

I created an account not long ago and everything else did go smooth!

Hi friend

Please PM me your details or send an email to sales@kaidomain.com for further assistance.

Please donā€™t be worried. We will send the email activation email to you later.

Thank you

It was around 4:00am my time when I posted that and it is not 9:00am that's 5 hours for a conformation email.

You guys may be the best on the internet, I have no idea as I have never made a purchase from you. I know for sure that you have in stock parts that I need.

Problem is that everything we do like you making a sale and me making a purchase. All of that is handled through your server and for some reason it is really bad at sending out an email to activate my account,

The last thing I would allow in my store is anything that would keep my customers from making a purchase. I will talk with some of the senior members as they will know you. I will ask their experience with you and make a decision then.

But I am not going to email customer service in order to become a customer. I shouldn't be working to purchase from you, you should be working to earn my business.

Sorry if that sounds cold. If it makes you feel better. Amazon they love my wife, and they really hate me.

Hello,
I am searching a wide optic for Cree MC-E RGBW LEDĀ“s. I checked your shop but i can not find one. Hope you can help me out.

Hi Terry

Thank you for your advice.

I am sorry for the inconvenience of our system.

We will continue to improve and upgrade all our existing systems.

Hope you can be patient and understand with us.

I am always on here.

If you guys has any urgent matter, please donā€™t hesitate to contact me.

Thank you

Ban

Hi TheOnlyDocc

Yes, we had some optic for CREE MC-E RGBW for a customer before.

Would you mind what is the angle or dimension( dia x height ) do you want to have?

I will check our warehouse to see any optics for CREE MC-E available now.

Thank you

Ban

LOL you have to forgive my impatience. Seems like these days all I do is work. Even if I am at home I am working.

@BanL
If the optic is smaller than 40x30 everything is fine. It should have a wide angle and it should help with mixing the colors.
And if the optic is bigger please let me know. Maybe i can make it work somehow.
I need at least 5-6 optics.

Thanks for your time!
