It doesn't matter how high the power is set which is at the most high setting. The spotlights do not work.
Why?
Okay, first of all, there is a 4.x version of the Blender Basics:

and second, the spotlights work.
I don't know what you are doing wrong: just saying something doesn't work is not enough information for me to do any troubleshooting.
