Light Going Through Wall

I have a stationary light, inside of the room where you can see the door, in this image. It seems it travels through the walls into the hall as shown in the image as well, how can I go about resolving this?

Hi!

It looks like your mesh have a light map with low resolution and light build with low quality. Use this troubleshooter. I think it help you.

Thank you for providing me with this. I did see changes when changing the resolution, though not completely getting rid of the problem, I will look more into this with what you’ve provided me.
