For a great light with more than just 3 modes, check out the
Quark AA (as in 1xAA). Common battery and modes from a minimum Moonlight mode of 0.2 lumens to a maximum of 109 lumens OTF (out the front). The Quark AA2 with 2xAA has a higher max of 205 lumens.
From what I can tell, the 4Sevens Quark lights are made to the same standards as Fenix, but with a broader range of output.
IMO, FWIW, $.02, YMMV -- Caveat emptor, yada yada yada
