That is the led I tested, although I bought it from rs-online and the test was done with the led reflowed on a 16mm Sinkpad board. I have used it in a Ultrafire M5 (small AAA light) and in a sk68-clone (AA-zoomie), I described it in that thread. Of course the amount of output was not all that special (but 96CRI, and it shows!), but because of the narrow emission angle it behaves very nicely in the various optics, in the sk68-clone the light loss is even less than the XR-E.
