Are we immediately (i.e. 8:20 minutes light time) in darkness or do we notice dimming the Sun after a few days / years ?

The issue is, how long does it take for the change in energy output to travel from the core of the Sun to its surface. A change in the core energy output does
not instantaneously change the output of energy at the photosphere.
After this initial delay, due to the time needed for energy to reach the surface of the sun,
then we have about another 8 minutes!
