i mostly own and carry 1xAAA. being so small, i can always have a couple on me.

here's a pix of my custom 120-lumen MillerMods Arc, Mako, E05 and DQG Tiny.



i do try new 'lights now and then. lately i've been playing with a tactical clickie light: a JetBeam PA10 with 14500 3.6V rechargeable Li-Ion battery. this little 1xAA puts out 650-lumens.
