Hello everyone!
I made this simple calculator in sheets for calculation of mode spacing, based on the cubic square law (You need x^3 as much current for x as much light), to calculate modes for drivers.
I plan to update it with lumen values using public information, if that would be okay with the original creators.
The idea of this project is to help people with mode selection for their flashlights, especially for high (2000+) lumen flashlight, to still have nicely spaced lows.
