Please educate me on Nichia 219 LED's.

First of all, I would say to check out this link.

Cree, Luminus, Seoul Semiconductor, and Nichia LED comparison

I would suggest reading my guide on tint, binning, and CRI before reading this. This is a comparison between all of the common LEDs. The LEDs included are: XP-G, XP-G2, XM-L, XM-L2, XR-E, XP-E, XP-E2, Nichia 219, SSC-P7, MC-E, SST-50, SST-90, MT-G2 XP-G The XP-G is a small Cree LED that is 3.45 mm by 3.45mm. The size of the die is 1.4mm by 1.4mm for a total die surface of 1.96mm2 which is often simplified to 2mm2. It is distinguishable by it's size and the grid of 4 strips. [image] It has…

But to answer your questions: Nichia has only released some numbers, but I will put those into a graph for you and post it. Yes, only the H1 bin is the High CRI one. They are almost exactly the same size, one of the differences is the size and shape of the anode and cathode. Despite this they work quite well on stars meant for XP-G LEDs. I have personally never seen a listed beam angle, but I will look around a bit more to try to find one for you.
