The banks are called presets and it looks like program modes 2,3 and 6-15 can be stored on one of the three presets. The presets are the first mode once in programming. Momentary options, the number of levels, the power of the levels, thermal settings voltage settings and other options can all be customized for each preset.
The lowest low is lower than my haiku 119V. I'd guess it at the 1-2 lumen range??? I am curious to find an easier way to determine the drive level from rush. Brightness level 1 of 21 is "x" percent of max current setting. What's "x"?
As far as pwm, I am not too good at detecting it. I tried last night but couldn't see it very well by sweeping it across the wall. Maybe PSM can answer that a little better.
