But there are these 2 lighting options that look exactly the same.

If you came here after reading the Developer Hub’s pages on both the SpotLight and SurfaceLight, I’m assuming you need a visualization/reasons to use one over the other.

In the screenshot below, I’m using a SurfaceLight and SpotLight at the same brightness.

Here, the red light is a SurfaceLight, illuminating the entire bottom of the part.

The blue light is a PointLight, emitting from the center of the object.

SurfaceLights will illuminate the entire surface of a part or attachment. SpotLights will emit from the center of the object.

In cases like below, I suggest instead putting the light inside an attachment and setting it to the position you need.



To visualize the emission from the lights in the screenshots above, I used this plugin by Ozzypig:
