Experience of using lights in Maya

I have been experiencing different use of lights in Maya like Ambient light, Spot light, Point light and directional light.

I have been messing around with options with lights with the help of the website telling me most important things about lights such as increasing light intensity, using shadow ray, use of anti alise option and much more.

Each picture use a plane in initial lambert and Cylinder shaded as royal blue blinn.

Third picture is Point light in maya software, although, I couldn’t get what the tutorial try to pull off but I got the general idea how it works:

Lastly, Spot Light picture; its quite interesting:
