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.
white light is the full visible like spectrum. lasers are monochromatic. a single or very narrow frequency or wavelength.
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.
The difference is their wavelengths.
In flood lights,the source of light is placed between the pole and focus of a concave mirror so as to obtain a diverging beam of light..
No, flood lights do not use more energy. If the wattage is the same between a flood and a spot light, it is the wattage used that you pay for. It is the lens of the bulb that determines the light output pattern. A smooth surface will give a flood pattern where as a spot has a lens that focuses the light into a central location. A reflector flood has a silvered interior to direct the light outwards on to an object.
There is no difference.
It is called an absorption spectrum.
Difference?? There is no relation.
flood.
