Why we can see little light even after main power is off?
In Don't Breathe (2016), a blind man turned off the main power so robbers won't find a way out of the basement.
But we can still see the chracters' movements in the dark, how?
Best Answer
It's for the audience to follow what is going on in the movie.
The characters are completely in the dark (we can see that by their eyes), but the audience wouldn't want to spend 5 minutes just listening to sounds, without realizing how close characters are coming to one another. Using this technique, the audience is kept on the edge as the robbers and blind guy explore the darkness.

Is it normal for LED lights to glow when off?
So, essentially, if your LED bulb is giving off a dim light even when it's turned off, this isn't an indication that there's something wrong with the bulb but rather that your lighting fixture still has a slight electrical current going through it even when it's off.How do you fix a ghost current?
It can be cured by adding a lighting capacitor in parallel with the light fixture, providing a path to neutral sufficient to pass most of the ghost current rendering to voltage at the outlet to low to activate the lamp.What is the main reason why we Cannot see very well at night when we first turn out the lights?
The problem is that rhodopsin is so sensitive to light that under normal light levels, the light deforms and deactivates (photobleaches) this chemical.LED dimly lit, or glowing, even when switched off demo
