Been thinking about the levels some more. Can you list the bulbs that you envision for Level 3, and their "optimum" voltages vs the actual Level 3 voltage of 7.5V? Basically, if there is some spread of the optimum voltages for say an MN15, MN20, and other bulbs about 7.5V, then I might want to specify re-programming of the Level 3 voltage that might more closely match some bulb of interest whose "optimum" voltage might be closer to 7.1V-7.3V. If such a case exists, then this might also better accommodate a WA1111/64250 than the current Level 3 voltage of 7.5V, providing a level that can drive the bulb a little harder than Level 2 but not so hard as to risk erratic filament life.
Thanks.
Unless I hear otherwise, I am going to assume the default values/behavior for those orders:
Level 1 = 5.0 volts
Level 2 = 6.8 volts
Level 3 = 7.5 volts
Level 4 = 10.8 volts
Default behavior for almost depleted cells = Moon Mode
Moon Mode means = PWM duty cycle goes down by 1/2, so output RMS voltage goes down approximately 30%.

Will, if it is not too late for my 2nd regulator to order it with custom changes, I would like these settings:
Level 1: 6.8V (MN21 & 1160)
Level 2: 7.4V (MN15, MN20, N62, 1111)
Level 3: 9.3V (1164, Hikari 5607)
Level 4: 10.8A (1185, 1331)
