Electric lighting allowed factories and work - places to operate for longer hours. This effectively expanded the time available for production activities, which was a significant boost to economic development. Option A is not directly related as cost - management was not the main impact. Option C is incorrect as it did not limit production geographically. Option D is wrong as electric lighting did not necessarily lower energy costs for manufacturers.
