How to set indirect lighting on an object?

Hello, i have been trying to create a blue spotlight in some objects like washing the material and lighting the bottles but lights seem to look more general and i want it just to the object, i have tried spotlight and IES light but i don’t know if i’m making the right adjustments, please if someone could help me i’d really appreciate it.

I assume you are referring to doing this in a rendering application. Which one?

Yes, sorry i forgot to mention that is Vray, this is the object, i want to create a blue light coming from below the bottle
