This past weekend we had to cancel a symphony concert and evacuate the building due to a power outage caused by a blown transformer. This incident has cause some discussion on the amount of time the emergency lighting is supposed to last. Our current emergency lighting lasts approx. 30 minutes, but during the follow up meetings and such we have been told that by code they are supposed to last 90 minutes. Is there anyone out there that could shine some "light" on this issue so we have a better understanding. Under code how long should emergency lighting last? Thanks in advance.
