KD (kaidomain): Deals and new products thread

And Ban did not respond to that post? :expressionless:

Ban, did you check your current inventory of XHP35 Hi 4000K 80CRI? If these are indeed 80CRI, could I have a replacement of the two wrong 70CRI ones from last year?

Hi

Sorry for the replying you late.

Do you have any order number so that i can refer to?

The current wheel is in CRI80.

Thank you

Ban

No, I’m sorry. I never created an account on Kaidomain because it works fine to send the goods to my PayPal address. And it was still on the old site when I ordered them and your order conformation mail when the old site was still on, did not contain a summary of the ordered items, just an order nr and the amount of money. There is no way for me to know which of my 2018 orders were these leds.

So there’s no order nr coupled to the leds. Maybe it is in your administration? (I’m sure there’s just one Jos from Amsterdam :slight_smile: )

Yes, we get a customer that is used for the SST-40 dedomed LED.

I had tried to reserve some for selling.

Hi djozz

I will ask for our colleague to help to follow for your problem.

Sorry for any inconvenience cause to you.

Hi Ban. I ordered 3V XHP50.2 K2 2A, but it is missing in the order. I received everything, but not this. Interestingly, on the invoice is marked ok.

I tested tint of the new batch of KD’s 2700K SST-20 leds, claimed JA3, that came in today.

Kaidomain’s previous batch was JC1, which should have been just above the BBL, I tested the tint here: KD (kaidomain): Deals and new products thread - #1222 by djozz , and, at ~400mA, from above and at 60 degrees the tint was under the BBL, just in the hotspot from a OP reflector it came very slightly above the BBL.

This evening I did the same tint test on the new claimed JA3, which should be under the BBL, and all three tints: straight above the led, at 60 degrees and in the hotspot of an OP reflector, measured almost exactly as the previous batch of claimed JC1 bin.

Also visually I can not tell the “JA3” led tint apart from the “JC1” tint.

This is an extremely nice led if you like 2700K light, nothing bad about that, but this is not good for trusting tint bins that are offered by Kaidomain, no matter where the problem is, at KD or at Luminus. Apparently everything must be checked, which costs money and time.

I bought 7 of these, if I had known that they were the same as the previous batch I would not have bought them, as I still have a few of the previous batch leftover.

OMG, that’s disappointing. I was waiting for your test before I buy a bunch. Now I’ll hold off on buying them. Thanks for sharing your data.

This is bad news. It's probably the sourcing. From dealing with other stores, they really honestly believed they had accurately labeled parts, but when pressed, it was totally dependent on the word of the supplier.

There’s a photo of the reel so someone will have some explaining to do.

I have bought some. Can’t wait.
By the way, if you have some XHP70.2 de domed I would definitely be interested, since I don’t have the skills nor the courage to do it myself.

I really do not know why there is no difference, the resolution of my spectrometer should discriminate between them, and visually next to each other I expect a tint difference too.
In principle the two tested leds could by chance be close to each other because the JC1 and JA3 bin share a corner with each other, but I would not see that as the most likely explanation.

This makes me sad :frowning: I suppose the JC1 led you got could have been at the same bin boundary as the JA3… Unlikely though and I suspect something is up with KD, their supplier or the manufacturer.

Also, I should have known better to order some before they had been tested :person_facepalming:

Waiting for someone to test the 2A xhp50.2 3v also

Someone reported SST-40 N5 bin is no different than N4 bin, 80CRI rated leds were in fact 70CRI etc., my guess is they know what they're doing, for example they got N5 SST-40 reel but since they want to get rid of N4 bin leds, they sell all leftover N4 bin as falsely advertised N5 first. Similarly, first they want to sell all JC1 SST-20 before they open JA3 reel (but of course they will put picture of JA3 reel because BLF told them it's better regarding tint, so they will probably sell easier).

Bin difference was very hard to detect few years ago because almost no one on BLF had equipment to do proper tests, but now few members have ability to measure CRI,CCT,duv.

Don't be too naive, this bin scam is old news.

And the same as the XHP-35 HI D4 vs XHP-35 E2’s, XP-L V6 vs XP-L W2’s and XP-L HI V2 vs V3’s. RMM got burned too…

Although I’m not ruling out the possibility of what you say is true, I think it is unlikely. From talking to Texas Ace who has been involved on many different flashlight development projects from different manufacturers, he thinks it’s likely that KD got scammed by the same SST-20 supplier who recently sent him some sample FA1 tint bins that are really FB4 tint, which of course he didn’t end up buying. KD on the other hand, probably does not have the equipment or manpower to test every incoming emitter. Another possibility, but less likely, is that Luminus labeling is not to be trusted. TA has an order direct from Luminus and I’m curious to see if the labeling will be accurate.

Hello BanL,

Earlier, I asked for SST-20 J3 (or J4) GD2 95CRI 3500K.

I would like to tell, that I still need them, if you can source them - but my main goal is now just the CCT, so any of GA3, GB4, GC1, GD2 is fine regarding tint.

Could you please make a try for sourcing them?

Thank you in advance

Hi Adam

I just have some SST-20 3500K left on hand.

This is the LED code VH J4 GB4

Please let me know how many pieces do you want to have.

Thank you

Ban

I would like to ask for 8pcs on 16mm star and 4pcs on 20mm star for now (at some time later, I might need more as well)
