I already own a Fenix L1D-CE and it's nice, just looking for a few other
options.
Throw is a MUST, the tighter the hotspot, the better.
I will also be using a 1xAA rechargeable setup.
Agree w/ the M3 turbo. Only downside is that it's probably the largest of all the AA setups.
Anything w/ a Cree and smooth reflector will throw better than a Seoul and/or OP reflector. The wider and deeper the better but the tradeoff is a bigger light.
