I must admit I had the same doubt as Ludwik and figured it depended on
what one means by "flash". After all, if I take a bulb and "wave" it
back and forth, I don't see flashes like those I see with an LED light.
However, I searched for a slow motion video of an incandescent bulb and
found a couple that showed a noticeable flicker, if not a flash. Does
it depend on the type of incandescent bulb?
