The power consumptions are approx 1.05A for the Malkoff and 0.54 A for the TerraLux according to my Fluke 189 across the tailend of each.
You can predict the rest from that. The Malkoff has way more output but is also more expensive. The TerraLux SSC P4 is a very obvious improvement over the TerraLux K2 that also consumes about 0.54 A so the K2 version should be considered obsolete.
As published elsewhere, the sweet spot for the TerraLux insert is 4 cells (or up if the size doesn't bother you) so it will run a lot longer given the lower power consumption and its preferred configuration.
My thoughts
1) The TerraLux is a very nice drop in mod for the 4D Mag. Ample light for almost all uses and a reasonable price.
2) The Malkoff is the output winner, by far, and the choice for a tactical stunner or across the beanfield light.
3) Malkoff makes a low output version of the SSC P4 with drive set at 0.5 A. I don't see an obvious reason to buy this instead of a TerraLux insert that is a lot less expensive though it will porobably outperform the insert for efficiency by a bit.
3) Matt and Gene are both good guys to deal with - you won't go wrong with either.
My version of how to choose
If you have to buy a MagLight to hold the TerraLux, spend the extra $ on the Malkoff unless you want the much longer runtime of the TerraLux - as in candle mode after a hurricane power outage. We get those lasting days up to a week every couple years here on the NC coast.
