Does anyone know when it was first required that you need a switched light in a room. I see the 210.70 first shows in 1981 NEC but was there another requirement that predates this?

That would be 210-26 in the 1975 NEC.

That required lighting fixture locations was added to the 1975 NEC.

Jerry, Thank you so much. I have a gap in my code books there. Looks like I need a 75 code book ;)

Just a side comment. The requirement is for a switch controlled lighting outlet, not an actual fixture.

Right, for a wall switch controlled lighting outlet

Jim, Good point and correct. I know sometimes when I ask some questions that I am being a bit loose with terminology/definition.
