I am also +1 about the status of current flashlight situations.
I would like the idea of the 9V (3 LED’s in series) version of the driver, as well. Then, we can use E21 or other domeless and small die LED’s for the best throw with 10507, assuming using the existing components. I would go with 18650 for the diameter of the tube, meaning narrower. With 10507, the height will be shorter, too. For the AUX board, we can maximize the output and put E17 or other small LED’s for the flood and any color combinations. The AUX mode can take care of the moon mode, too, for the better optimization of the main circuit.
It is not my priority to have the maximum TURBO mode, either. Especially, with the configurations of the Lume1 right now, the Turbo mode will be less bright than the maximum regulated mode as the battery voltage gets low.
The wires for the AUX board are coming next week. Hopefully, I can swap the driver with Lume1 without too much difficulty.
Thank you very much for all of the tips and ideas for the assembly.
