I disagreee. I can select the level I want *before* or after turning on the light.
One standard Mag light switch for off/on or bursts, and one pot for low to high in well under a second with the flick of a thumb.
No pushing for one or twisting for something else.
I may not have been clear. On the L1 you can use either the momentary push for activating each of the modes, or the twisty cap, once again to activate either of the modes. You select modes simultaneously with the activation, and you have two different methods:
If you want light just for a short time, you thumb-press the momentary switch. If you press "softly", you get low. If you press "hard" you get high. Momentary instant selection of either mode, just depending on how hard you press.
For the twisty operation, as you start to tighten the cap, low comes first and then, after a few more degrees of rotation, high kicks in.
I've found this to be fantastically simple, fast and reliable. Only downside is that will only work for two-level lights.
But, as in most affairs, I guess it does come down to personal preference...
