How to get intensity in blueprint

My goal is to use a Level blueprint to alter the intensity of a light and then return it back to the initial intensity. I don’t see a GetIntensity node and do not know how to pull in this setting. If I select the light in the main editor and then use the context sensitivity in Blueprint I don’t see a get that seems to work.
I’m new to UE4 so any blueprint theory and how to’s for this would be very helpful!
