I don't hold out hope for these. You're looking at hundreds, if not thousands, of USD per diode. Buying diodes straight from manufacturers has been tried by people on here, and it has never worked out. It always comes out cheaper to buy the sleds, since the sled makers are buying diodes from diode makers in much higher quantities than we could ever hope to achieve.
These makers don't care much about selling 100 diodes, they care about BIG buyers. Good luck, but don't hold your breathe.
