I EDC a Countycom Martac AA size, one for battery standardization and also because I prefer that it start on the LOW (1.5 lumen) setting. Most lights I have tried start on high (like the Martac AAA Aluminum) or some on medium (like the Martac AAA in its earlier form - SS and Copper are still that way). I find the 1.5 to be great for night adapted eyes, the 18 for the city and I almost never use the 85 except when looking for the black cat :-).

Respectfully,

Jerry
