Depends on what kinda darkness we're talking about....😉😎

!!!!!!! GMTA P.S.-my great great great grands are from Deursen. I knew you would get it!
That's nothing, my great great great great great great great great great great great great great great great great great great granny's grandfather was from the dark ages and even he couldn't escape the dark.

It's not uncommon for mechanical and mechanically operated switches to take 50 milliseconds or more to move from the on position to the off position and then they will bounce and make on and off contacts several times before coming to solid rest in the off position. Bigger switches bounce longer.

Technically there's no in-between state to on and off, but there is a rapidly repeated on and off sequence for a while, as the mechanical contacts bounce.

And don't forget during this time the AC voltages is going up and down, positive to negative and back every 16.6 milliseconds. And the filament takes a few milliseconds to cool off to full dark

The type of wiring and the distance between the switch and the bulb can also affect how quickly the light turns off.
Essentially, while the switch turning off is an instantaneous event but, the lightbulb's behavior after that can vary slightly depending on the technology used.
Fluorescent bulbs:
These might take a few seconds to fully turn off.
LED bulbs:
LEDs themselves turn off very quickly, but any capacitors in the driver circuit might cause a brief, faint glow.

However fluorescent tubes covered with a Lunaglow sleeve (while the company existed) stayed glowing for 24-26 hours when fully charged (after about five minutes) causing the speed of dark to be severely stuck in the mud.

They were made of a photo-luminescent material like the glow in the dark escape strips on the floor of airliners and were great security lights because they never went out as they also "charged" in daylight.
 
That depends on the IQ of the governments legal drafting drones. In Australia this is severely hampered by the stratospherically high speed of stupidity of the governments legal drafting "experts".

In 1991 the Australian Office of Legal Drafting wrote a civil aviation law that said "second hand parts shall be ...... certified as new". Their law on the subject was four pages of bureaucratic gobbledy gook. The US and EU equivalent laws that came in to existence a year earlier were three clear paragraphs. They were also at least 90% word for word the same.

The same pack of highly overpaid geniuses wrote a two page tax form which "required" a 144 A4 "booklet" on how to fill in that form. Worse still that "booklet" was only in English.

The UK Copyright Act is 254 pages. The equivalent Australian Acts (there are three) are over 1,200 pages and include such stupidity as when you get a copy of something from a library that copy has a newly created copyright that belongs to the Aus government and that you cannot photograph, scan or photocopy or in any other way share that copy with anyone else.

If brains were gasoline they would not have enough to start a cigarette lighter.

I agree 100%!
