I remember reading that Malkoff M60 units are also known for the inconsistencies with their beam profile. Something to do with getting a proper alignment of the optic to the LED. That is one of the reason Malkoff went with the M61 design.I don't know how far an LX2 throws. I never used one.
My 3 cell Elzetta throws an honest 150 yards down my road on a dark night, with enough light to see anything I need to see.
The M60 has a tight optic of 8 degrees, and it throws pretty good. And the famous Malkoff beam quality and tint are really nice. The M60 is what made Malkoff's reputation. It's really good. XRE-Q4(I think) behind the 8* optic.
I really don't think there is any difference in throw with 2 cells or 3 cells. Just a runtime difference.
