I've been looking at the XPE-2 recent LED by CREE. On paper it looks pretty good, with decent luminous flux, thermal, and color characteristics. In fact you can get most color variations from high CRI to neutral white to cool white. The cool white doesn't even sacrifice all that much in lumens.
But what is getting me even more excited is that the XPE-2 might be a very good thrower, of course no contest with the XM-L where throw is concerned, but probably also beating the XPG-2.
Now, when I look at flashlight offerings these days, the XPE-2 seems mostly absent. My best guess as to why this is: everyone and their brother is busy putting out huge-lumen monsters using the XML of XML-variations, and the XPE-2 is not designed for that (according to specs it maxes out at 1.0 A).
So one question for the knowledgeable posters here, am I missing something regarding the XPE-2?
My second thought was whether I might be able to use this XPE-2 in an Ti PD-S.
The Ti PD-S was, and is, a pretty good thrower for its size. So I got excited thinking how much stronger a thrower it might be with an XPE-2 replacing the original (SSC, I think) LED. Even the original converter might work, in fact as best I can tell from the XPE-2 specs, forward voltage at 525 mA (the high of the Ti PD-S converter) is around 3.0 V, pretty close to the 123A primary battery feeding the LED.
What I don't know is whether the reflector of the Ti PD-S would match the needs of the XPE-2, and how easy it would be to do the conversion/mod.
So any knowledgeable replies would be most appreciated!
