Lamp: Spilling through solid object?

Hello,

Can someone direct me … how can I stop the lamp from getting through the solid surface of the ceiling?

Hi,

I’d enable either Ray Shadow or Buf. Shadow in the lamp settings, enable Raytracing in the Scene options (if using ray shadows), and render the scene.
