What lights are out there with 2 level twisties? That means you turn it partway for low level, turn it further for high level.
I know of the original Li14330 which had an ingenious and slightly complicated spring contact on the PCB to get the first level; also the leaf-spring resistor gizmo that was retrofitted to some Dspeck Firefly lights, plus the CR2 Ion, some Arc LS* mods, and I guess the McGizmo PD lights can be operated in a 2 level twisty mode. My 2-level Firefly never worked very reliably but Cy had some posts about how to adjust/reconfigure them for better performance, that I never tried.
Anyway I think the 2-level twisty notion is pretty intuitive so I'm wondering why it never caught on. Did none of them really work that well?
