Arc swirl on a SON lamp!!, is that even possible?

Ok, bear with me here!, my GE 50watt SON-T has stopped flickering now, and started arc swirling!
I`ve only ever seen this in halide lamps running vertical, where the arc leaves the electrode tip, with a slight bow, (vertical running don`t forget), then wanders around the tube causing a swirling motion reflected on the wall next to the light.
My GE in its coach light, puts a rectangle lit shape, as it shines through the window on my bedroom ceiling, and if you watch this shape carefully, what seems like a flicker at first glance, is a definite shadow that goes back and forth within the rectangle!
The only thing I can put this down to is arc swirl!, but I`ve NEVER seen this in a SON lamp before, (with the arc being very constricted within the confines of the narrow tube), your thoughts?????
