XP-L HI looks awesome in the LF2XT. I wouldn't trade the loss in lumens with the XPE2 for what may be a little bit more throw. You're going to get so much more light overall from the XP-L HI with really good throw.
Very intresting, I didn't know an XPL would perform so well in the LF2XT
JORN- I put a 4000K XPE2 into an NC EX10 and it turned out awesome. It's a very good thrower
