I have this problem with the shadows
I have lumen on and its my first time using it so this may be a simple fix but i still dont know how to fix it.
Thank you in advance 
The lights appear because of a harsh light angle. This shouldn’t be difficult to solve if you modify the settings of Lumen. Have you tried changing the settings?
This is known as the “Shadow Terminator Problem.”
The simplest, best fix is usually to add more polygons. Shadow biasing is another option.
