Emitter size of Cree XQ-E Torch?

[nikosb]

Does anybody know what is the emitter size of the Cree XQ-E Torch LED? In the data sheet it the diagram shows the LED base dimensions as 1.6mm x 1.6mm but the actual emitter is smaller than that. I need that information to calculate the die emittance.

Should be what the xp-e2 uses, or thereabouts.
