i brought the TrustFire TR-3T6 Triple XM-L T6 it runs cool for long runs and the screw in stays pretty cool all in all its great with heat and after 45 min runs the current stays pritty constant so i should have to worry about frying the driver as it does not climb to 4 + amps like the sky ray from other user reports on this forum, so the TR-3T6 should last longer, its good to know if i do fry the driver i can get a replament for it pretty cheap Triple T6 Cree Circuit Board Driver now only if trustfire made a 3 mode (h,m and low)
i think from this thread we figered out the driver is buck + bost.
