KD (kaidomain): Deals and new products thread

If you accept to resend my package without extra charge for that I will agree, otherwise I prefer to refund me. I do not want to pay almost half the price of my order for resending. Also my address is OK in KD. Prevoius I have only one order from you but everything was fine with shipping to that address.
Also from tracking of my package over Luxembourg post:

I didn’t know where is you warehouse but they will return package to the sender.

My latest order arrived today in a supersonic 6 days to the UK! and that was standard shipping .

Hi BanL.

Can you restock 29_6mm-x-24mm-Aluminum-Reflector-for-CREE-XHP70

BanL I would add if you can supply 3V (3 volt) version of XHP50.2 with 5000k (3C tint)

Just like this, but 3V:

Hi

I am seeing any stock in the market.

Once i get it, i must post it at once.

Thank you

Ban

My last 2 orders have arrived by rocket mail… 6 and 9 days to my door in the UK. Great service! thanks :+1:
You package stuff so well BanL - you obviously love your job :slight_smile:

Great! Thank you for your effort.

Hi. Do you know how long it takes PayPal to resolve claim.On 22 December I escalate about my order and to now I still waiting PayPal to resolve my case. I had very bad experience with KD this time.
I’m really sorry I didn’t order from AliExpress KD products. AE have better buyer protection compared to PP which sucks.

Communication is key icpart, whether here or there, and of course first and foremost believing conducively.

I've always had a great experience with Kaidomain. Did you send BanL some private message with a detailed explanation of your problem, and insisting on a resolution for it?

PayPal may take some time, but works (if done right, of course). Just be patient.

I had 20 or so orders since 2017. No problems. But sometimes his mails found their way into the spam folder, so I whitelisted his address. This would be one explanation for communication problems obviously.

No I didn’t. I just tried to communicate with them via mail. They just told me they wait to return package to them from post to resend me. After that I wrote mail to KD that I prefer to refund me. That was on 3 December. After that I never received answer from them. I waited to 22 before to open PP dispute. In dispute they just resend me tracking number from which is obvious that package is returned and not delivered to me. And that was only the answer in dispute. They didn’t answer me any questions send via dispute. After that I just escalate my case. In future I will prefer KD AliExpress store. It is little more expensive compared to KD website but AE protection is best in the world. I have won disputes for 2-3$ items. Also every time AE refund me very fast.
P.S
Finally today I received email from PP that they will refund me. So a month is resonable time for PP to resolve the case.

BanL, I’m looking at getting some of the XHP50.2 3V LEDs. It looks like the 6000K is out of stock? Will you have more soon? And any word on getting some of the 5000K version? Thanks!

Hi gchart

2A (6000K) version is out of stock. It is less chance to get it in a short period of time.

You can consider the 1C (6000K - 6500K) once.

I am still sourcing the 5000K version. But it has no news about that.

Thank you

Hi friends,

New Cree XHP35.2 HI is available now.

Cree XHP35.2 HI D2 1A White 6500K CRI80 LED Emitter

Enjoy :smiley:

Cool!
Thanks BanL. :slight_smile:
Any chance for something warmer?

… and CRI99? Wellp, CRI90+ is 0K. :-)

Hello.

I was going to submit some quick comments about the P4000 buck driver in Kaidomain's website; I used the opportunity to review the comments on the K6 flashlight host in Kaidomain's website, but found :!!!: none. Weird, because I perfectly remember having submitted a review of it…

Concerning the K6 host I can recall I gave it a 4/5. It has excellent heatsinking capacity. The tail switch is a big forward type and there's no straightforward easy way to convert it to reverse switch, although it can be done namely by DIYing a new switch centering ring out of some material. The Omten 1217 is a great choice for it, I used one.

According to what BanL told me past september very few hosts remain. I know this because I talked with BanL about getting a new reflector for the K6, and he said no way among other things. I finally realized the K6 uses the same reflector as the Convoy L2/L21A, so I got my replacement from Convoy.

About the P4000 driver, in all honestly I have not even powered it on. However, its sense resistor stack consists out of 50mΩ plus 1Ω sense resistors in parallel, which is 47.619mΩ combined. So, when 4A of current go across the sense resistor stack the voltage drop is 190.476mV and the power loss is 761.9mW. For 5A, voltage drop is 238.095mV and power loss 1190.5mW. These are huge figures. I can understand whoever designed the driver probably thought “it is good enough”, but I don't. In my opinion a switching driver needs to be efficient, minimizing undue heat dissipation, and this driver fails in this respect. This driver uses about the same sense voltage when in high/turbo as typical AC led driver. Using a 0.2+V sense resistor stage in an AC led driver outputting tens of volts is 0K, but using something so gross in a small driver meant to output not much above 3V is… inadequate. Lazy job from the driver designers, imho.

Like said before, any chance for CRI90?

BanL, could you comment on that?

I don’t usually take stuff like this to public forums, but KD has been a real pain for me lately. They don’t notify me of shipping (also don’t change the status on the website), sometimes appear to not ship stuff for ages, and don’t appear to have shipped one particular order I made a long time back. They don’t respond to my emails to their official contact address and don’t respond to messages using their contact form on the website.

Is there some secret to getting a reply from KD, just like Neal only ever responds on exactly one channel? Should I just get Paypal involved? I’m really frustrated by now. Am I the only one?
