LED bulbs are definitely instant on, instant off -- to the point where most are dimmed not by varying voltage but by cycling the power up over 100khz.

Got any pictures that show the banding you're talking about?
Thanks. I'm definitely not a sparky so I have no idea.
I don't have any pictures right now but I'll try to snap one...
