Individual lighting fixtures or entire light groups can be turned on or off to achieve the desired lighting effects in a rendered image. When you turn on or off lights in a 3D view, the settings are saved as part of the view properties, and they affect that view only. They do not affect rendered images for any other 3D views.
If a lighting fixture is a nested family that is not shared, you cannot control individual light sources in the fixture. Instead, you turn the entire lighting fixture on or off. See Sharing a Lighting Fixture Family.
