I've noticed a lot of bikes recently using Shimano Nexus(?) hub dynamos. At a walking pace these seem to emit a stream of bright flashes, a strobe if you like. My old faithful FER2000 just emits a dull orange glow at walking pace.
So what is the difference? The lights in question appear to be filament, like mine, but I can't tell for sure. They usually seem to be lumotechs.
Is the some sort of capacitance/inductance discharge going on?
I've tried a google but nothing obvious. Should I buy a SON?

a characteristic of direct drive hubdynamo's which turn slowly
