Since there haven’t been any updates in a while, I was curious if any place besides Kaidomain offers these. It looks like Mouser might (if you can stomach their shipping prices).
They say not in stock, 5 week lead time, but they also say the minimum order quantity is 1. I don’t know if that means they’ll stock a whole reel on the expectation of future orders if somebody orders as little as one, or if your order would go into limbo if you don’t order a full reel.
I don’t know if this is even useful to anyone, but since I took the time to find these, here’s the best bins I saw in the high CRI versions, XP footprint (A120). The “##2” at the end of the part number is a chromaticity bin kit covering 4 possible quadrangles, 2 above and 2 below the BBL. A “##1” would indicate 16 possible quadrangles. You can’t specify which exact bin you would get.
2700K - SST-20-W27H-A120-J2272
3000K - SST-20-W30H-A120-J3302
3500K - SST-20-W35H-A120-J4352
4000K - SST-20-W40H-A120-J5402
The 3000K version is equivalent to what Kaidomain has, except Kaidomain’s are known to be below the BBL. The 4000K version is one flux bin higher, and Maukka’s test showed the Kaidomain J4 version as roughly equivalent to Nichia’s D220 flux bin.
