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.
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.
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.
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.
Well, as for why I trust them and do not worry, similar LEDs like the XHP70/XHP50 had this problem being domed LEDs with gapped dies, but when being dedomed, the problem went away.
