Jouna, I believe both ThorFire and Sofirn are products from the same OEM with minor aesthetic differences. Examples: Sofirn SF30 and ThorFire TA13, Sofirn SF31 and ThorFire VG15S, etc.
kotobuki, if you are to reflow XP-L2 emitters on that triple you may aswell stack solder another 8-pin SOIC MOSFET on the driver and cream the Emisar D4's output records with the help of a Sony VTC5A or the newer Vapcell INR18650 2000mAh. LoL! :-D
