A "spot" is more narrow than a "narrow flood".
A light beam or beam of light is a narrow cone of light energy radiating from a small source. In optics, a ray is an idealized narrow beam of light.
A spotlight has a narrow beam that concentrates light on a small area. A floodlight is built so that the light spreads over a wide area. With a spotlight you will see things further away in front of you however it will leave everything beside you in the dark with a floodlight the reverse is the case.
The spotlight bulb has a different pattern cut into its lens that concentrates the light output into a tight central pattern. A floodlight lens pattern distributes the light output to a larger outside diameter there by spreading the light into a wide flood pattern. The spotlight has a higher light intensity output than the floodlight output.
Narrow lines of colors with no light in between them are called dark lines. They are typically seen in the spectrum of light when certain wavelengths are absorbed or blocked.

The difference is their wavelengths.
There is no difference.

A laser beam is a coherent light source that emits a narrow beam of light due to the alignment of its waves. In contrast, light from a tube light is incoherent and emits light in all directions, resulting in a blurry appearance. The difference in coherence and directionality between laser light and tube light accounts for their distinct characteristics.
You can go to sleep with the light on...
The main difference between light and x-rays is that x-rays are radiation.
