Possible to light up a single object exclusively in the scene?

Im new to blender and I recently worked on a title animation.
So while lighting up the scene I wanted the light source to fall exclusively on a particular object.
But the light was all over. Is it possible in blender to light up a particular object in the scene?!

Any tutorials on this? Someone pls help
