The light will affect objects in the selected layers. The light will affect objects in the selected layers.
[b]Note:[/b] The light cull mask is ignored by [VoxelGI], SDFGI, [LightmapGI], and volumetric fog. These will always render lights in a way that ignores the cull mask. See also [member VisualInstance3D.layers].

The light's strength multiplier (this is not a physical unit). For [OmniLight3D] and [SpotLight3D], changing this value will only change the light color's intensity, not the light's radius.
