Each time we enter the dark apartment hallway, I am reminded of Louis XIV’s proclamation in the year 1667 that Paris would be the first city in the world to be alight at night. The king reasoned that streetlights would surely make the streets safe after dark and thus promote trade and culture. As 3000 lanterns lit up the city, Parisians and the rest of the world saw that lighting in the dark was a great idea.
I think about this as our hands search the corridor wall for a switch that will give dim lighting that remains on just long enough for us to reach the elevator. I assume that contemporary frugality prompts the custom of dark corridors in "La Ville-Lumière"? Interior darkness never deterred us.
