How to I update multiple lights at once?

is there a way in the editor, or in code, to change multiple lights at once? As i have a scene with quite a few points/spot lights and adjusting them one by one is a bit tedious.

If you were to create 1 or more prefabs for your lights and instantiate your lights as instances of the aforementioned prefabs, assuming that you do not overwrite them locally or break the link to the prefabs, tuning the settings on the prefabs should change the settings on all of the instances of the adjusted prefabs.
