Hello everyone!
I got some leds from a friend but I don’t know them. The smaller one a 3V led and it looks the same as an XP-L HD as you can see on the pic but it is smaller. It has 2,45x2,45mm footprint.
The right one is XP-L and the left is unknown:
The other is a 4 die led that looks like an MK-R or XHP but not the exact same. It has 7x7mm size but at the bottom the fotprint is smaller than XM and a bit bigger than XP so maybe it has similar footprint as a lumileds luxeonV. I can’t reflow it without short so I soldered two wires to try it. It turned on above 9V so because of the 4 die I think it is a 12V type.
EDIT: it is a Lumileds luxeon MX. I just find it.
See it next to an XHP70:
