Arc-AAA vs CMG Ultra-G

I just received my G model and I do like it
although I do have some issues with it.
This is my first CMG purchase I do not have
a baseline reference. I will attempt to compare
Arc to GMG.

As I said, I do like this light but it pales next to Arc. The only area that the Ultra-G shines is in the longer run time. An Arc/finity mod will help the beam but the beam is the least item that needs improvement. Arc really needs to make a AA but I understand the reason that cannot be done at this time.

Agreed on all counts...That is why I was in no hurry to rush out and buy one...

Yep. I ordered a couple, because I can put lithium AA batteries in them and lose them in the glove compartment or spare tire well of my car until the next big earthquake happens, and increase the odds that I'll have a working flashlight when I really need one (and one that works in very cold battery-killing temperatures).

I consider this cheap as insurance. (I used to set up standard flashlights with lithium C and D cells for emergency use -- but people tend to find the flashlights and use the batteries up casually, which wastes their value.

Once lithium AAAs come out, Arcs will fill every niche.
