Got a maglight XL200-Love the output,will light the tops of pine trees,a little bulky,dont like the 3 AAA setup,for power hrs output they are lacking.Nice build quality.

Fenix E11-Just got it,two power modes,been using at work,very impressed size to power for one AA.I LIKE this light,a LOT.

Fenix EO5- Nice at 27 lumens and tiny well built keychain light BUT....looks like the LD01 with same size but three power modes would have been a better choice.

OK,thats where Im at for now.....AA and AAA,yet to advance to other batteries....yet!
