Help me identify these two unknown leds

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 2,45×2,45mm 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 7×7mm 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:

The 2.45 × 2.45 could be a Cree XB-H. The .pdf shows the same right angle triangle in the “Mechanical Dimensions” page.

The first one looks like an XB-D except for the bottom.

See http://www.cree.com/led-components/products/xlamp-leds-discrete/xlamp-xb-d and the .pdf datasheet therein.

Not sure about the second one… yet. Big Smile

Ooh, found a new one, an XB-H. It’s a G2 chip in the XB package. Got the .pdf, this one has the same bottom as the one you showed.

I found the second. Edited in the post above pics. It is a Lumileds Luxeon MX.
That was fast found for both Big Smile

The XB-D top also different. Mine has cutted sides of the dome like XP-L so maybe the XB-H is correct.

Btw, I was using mouser.com to find your unknown LEDs. It has some awesome filter options.
