How have you been enforcing the connections for the required emergency lighting on the exterior of an exit discharge? NEC 700.12(E) says to connect to local circuit which is, in strip malls, the exterior soffit or wall pack circuit. This is tough in tenant improvements because the tenant must now connect to the Landlord's exterior circuit which often does not have an existing unswitched leg.
Also 700.16 says the space cannot be dark with one lamp failure. Emergency light fixtures at the exit would have to have two lamps if a solitary unit. Is night time exterior light contribution acceptable as assurance against total darkness?

). I think the intent so that people don't all stop at the doorway when exiting a space that has lost power. If that is the intent, I think it is better to have the outdoor fixture connected to the same circuit that serves lighting in the store. Maybe your AHJ would approve this.
