I do not consider the 2L right now. The main thing holding me back is the wrong order in switching. Low beam should be first. I know that you can "double-click", but for this price -- no.
As far as two-stage lights go, I just love my Surefire L2.
To AFAustin: The low beam of the L2 is fairly bright. But it's a flood light. I can light up a room at night, but I don't know if the throw on low would be enough for your purposes.
The tailcap works extremely easy, though you have to hold light overhand (tactical, thumb on the button). You can turn the tailcap easily with thumb and forefinger. By turning the tailcap from the lock-out position, you'll get the following modes in order:
0) Lock out.
1) Momentary low, high is locked out.
2) Momentary low by pressing the button halfway, pressing harder gives momentary high.
3) Low constant on, momentary high by pressing button.
4) High constant on.
I mostly carry the light in mode 2, with practically no unwanted activation. In use, I like mode 3. It's one of the most functional switches I can think of.
