Here's a photo of my new EDC light, the Surefire E2E. It's on the left, with the Surefire G2 on the right and a 1911 for size reference. It's only about 1/2" thinner than the G2, but that makes a huge difference for pocket carry. Plus, it has a pocket clip and click-on tailcap. The bezel has slight scallops as well, so you can tell it's on when you set it bezel-down on a table.
Performance-wise, it throws a bit wider light, thanks to the smaller, shallower bezel. Output is the same as the G2, with a bit mroe runtime. Best of all, it slips into a pocket much more easily than a G2, which means I have no excuse to go without a light now.
