That site is very interesting. Appears they have almost the entire lineup of Nichia emitters (or they can get them at least). Shipping to the US using DHL appears to be only 9.99 euro, not terrible if the order is large enough. Hopefully you can get some to test muakka, as having that as a backup to Clemence would be a decent option for the 219Bs, and some of the rarer tints in 219B, 219C, 144A, and E21A.
They also have this affordable color temperature measuring tool, which also reports the cie xy coordinates and lux. The “service” headers might be accessible with a serial interface for logging (or maybe it’s just for reprogramming the atmega’s firmware).
If they are some sort of meaningful and intelligent led distributor, they'll probably be willing to make a deal. If they can manage to offer abroad inexpensive shipping cost orders, they'll for sure sell a few hundreds here at the very least. Worst case scenario is they may lose a little money, but if they do it right they will end up selling it all (and hence more to come) with a little marketing.
