Hey I found the specs for the X215 at energizer.com:

It says the light output is 7 lumens (MiniMag is 5.3). So I was right in that it is brighter than the MM. Only thing I don't like is the short lamp life.
PJ, how many bulbs have you replaced during the 2 years you've used it? Also, how do you reform the contacts in the switch, is it the little copper plate on the inside of the battery chamber that has to be moved in order to allow the tailcap switch to break contact? BTW, does yours have the tailcap switch that twists on and off?
