I have a surface light (1) that is passing through a part (2) and hit the ceiling (3), even it’s pointing to the bottom (floor):
Why? How to avoid this?
Set the angle to 0, 180 or 360. Failure for that to work try increasing the range & decreasing the brightness.
If you’ve rotated/titled the part it’s possible that its bottom facing face is in fact its relative top face, or some other face (try playing with the “Face” property).

To make it easier, could you test it on this project?light.rbxl (32.4 KB)
Here the answer:
You’re going to have this issue with any of the light types as long as you’re using one of the voxel-based Lighting settings. It takes a part something like 8 studs thick to completely block any light source in any of the voxel modes (Compatibility, Voxel, Shadowmap). Setting Lighting.Technology to Future will have the behavior you expect.
Changing the Lighting.Technology from ShadowMap to Future solves this problem.
