If you can see the change it isn't the filament drawing current.

Just the opposite, Martin. An arc strikes and quenches instantaneously (up
to several microseconds really, which isn't actually instantaneous, but it
would appear to be to the human eye). Only a filament's heating and
cooling would cause a visible ramping in brightness up and down.

I don't buy it Lloyd You claim you can see a light bulb start to glow
and then light and then when shut down the glow goes down in stages ?
If the filament was being heated by an arcing across plasma stream it
would ramp up in real time and could be seen. Either as a broken
filament or across the 'skin' of the tungsten which heats up the filament.
I have a degree in Physics and 20+years as a EE. A heating filament is
simply to fast to see and the eye integrates the changes.
