John:
Your right . I've read the beging of Article 700, and found out thats the one thing it doesn't say.
EM lighting is not a NEC requirement.
But I have to conclude,if emergency lighting is required by some authority, then it would be required in all areas of a building, not just the biggest portions.

My point with the first reply was that you have to be able to see with some minimal amount of light everywhere for purposes of exiting, when EM lighting is required.

PS I check with our fire chief to see what he says.
