Lightbulb More detailed measurements

Well, I added a current sense resistor (1 Ohm) to the setup, and connected a scope.
X axis is time, 1 second per grid. Y axis is current, 100mA per grid.
The small "1->" marks the zero current line.
Screenshots were done the lotech way, with a camera.

First some measurements with files in internal memory:
