Only about 1000-1500 LEDs are left before we can begin the order process 
I will take 10.

Good news:
“I have an interesting question: can you manufacture very low color temperature LEDs after this batch?
By low, I mean <2500k(1800-2200k).”
“Sure, no problem making them.”
I am in with 10 pcs.
Thanks BlueSwordM for your great work about that to bring to us that new Hi-Cri LED.
No problem icpart.
I knew the community was searched for such an LED for years, so I decided to pull up my overalls and get working!!!
Added to the interest sheet.
Bluesword, thanks for organizing this group buy.
I am interested. How would this LED be different, better/worse than the Nichia 519a?
How it’s better:
- It’s domeless. If the tint binning we asked for is achieved 100%, it should have better tint behavior in most optics than the 519A.
- It’s 5050.
- Because of the larger surface area, it should be handle to handle more power.
- It should be a bit more efficient than the 519A(barely though).
How it’s worse:
- Not guaranteed R9 >= 80 like the 519A(only R9>=70).
- It’s not 3535 obviously.
- When dedomed, the Nichia LED will be more throwy/lumen.
The 5050 footprint part is the most important by far: it allows us to replace so many lights that use XM-L2s/SST-40s with a better tinted less tint shifty high CRI LED.
That’s about it.
Silly me, I looked at the diagram a little too quickly noticing 2.9mm x 2.9mm not paying attention if that was the LED base or the die itself. Yup, 5050 def the biggest differentiator here. Looks like a nice find for SST/SFT40 lights that push alot of current that 3535 LED’s can’t handle.
These look great! I’m in for 20. Thanks!

If you can get a Wechat contact, I can communicate with them and see if maybe they would be willing to send me a sample. Shipping should take only one day since I’m in the same city. I’m not sure if they have some available already though.
I can test lumens and candela (I’ll probably put it in a C8 size body), but can’t test CRI or tint.
@fogofwar, problem is that samples don’t exist for our specific CRI and other color don’t exist, but yes, you could check out the beam profile.
Pavlo and Rayoui have been added.
I’m interested in 5
Nice!
Do i have to sign up here or can i fill in the Google document later?
Definitely interested in a few

Given that there is a small gap between the dies, I can not think of a reason why there will not be a visible donut hole in the hotspot when used well focused in a smooth reflector, like we do in flashlights. It may be limited but it will be there, and an OP reflector may be needed to smooth it out.
The manufacturer may not realise that that is how a led is often used in a flashlight, as opposed to general lighting/car uses.
10 for me 
In for 10.
Thx
+1 and IMO it’s necessary to test this before making any large order. If fogofwar can test a sample that would be great.
