Lights in 3D Programs

[Vengeance66]

I know that lights in 3D making is taking huge part in the rendering and I saw it with my own eyes. I'm using Cinema 4D and I saw that you can make many variations with the lights in a scenery.

Does anyone have any tips, tricks, tutorials for lights?

For example, lights for indoor, lights for outdoor (I know there is SUN and SKY in C4D).

It would be much appreciated...
