Since these LEDs are under 2$ on AE you can just grab a few and solder the good ones on DTP Boards
The ones on KD are very nice, worth the extra few bucks for me to know for sure what bin and voltage I have. With the AE ones we have no idea.
Ohhh - yes, forgot bout those specs. KD's SST-40's are marked as VJ, so should be 2.7V-2.9V, which is pretty low, and explains the high amps we can get from them. Yes, it's certainly something that is nice to know up front what that rating is when we order them from other sources. Fortunately, KD has been pretty good with giving us the details on bin, tints, manu part #'s, etc.
Hi friends
Another new batch of CREE XHP50.2 is arrived

Thank you
Me wanting 219C Triple in 5000K
I agree… Nichia 219C 4500k - 5000K 90cri leds would be great
Requests:
The new Lumileds Luxeon V led, in different colour temperatures.
And a new KD DTP ledboard for the Luxeon V (it has a different size footprint).
I second this request

Excellent idea djozz, the Luxeon V looks very promising by your test. I hope highier CRI will follow in a near future.
^ I fifth it.
Ban, I’ve sent you two emails about receiving the wrong items in my order but you haven’t responded yet…?

I’d love to build a Q8 with a dozen of these.
Hi Sledgestone
I will ask my colleague and follow your problem.
Please don’t be worried.
Thank you
Ban
Sure. I will try to source it from our supplier.
Thank you
Please post updates on Luxeon V and the DTP boards for them if progress is made. Really looking forward to trying them out.
Ban, is it possible to make a special DTP-board for the Luxeon V ?
I understand it is a risk because it just will fit the Luxeon V and not any other led.

Great news. Thank you!

I am interested too! Nice test djozz! I am eager to see what this led can do on a DTP Board that uses the complete thermal pad of the led.
And would it be possible to source some SST-40 in 5000-5700K in N5 or P2 FluxBin and VJ VoltageBin?
Would KD be interested to sell some of the FETs that are used on the drivers?
- BSC009NE2LS5ATMA1 (https://www.arrow.com/en/products/bsc009ne2ls5atma1/infineon-technologies-ag)
- SIR404DP (https://www.arrow.com/en/products/sir404dp-t1-ge3/vishay)
It would be great if KD would have their own FET driver.
There are not so many good ones out there (with good parts on them), so I think there is a market for it
