Abstract
Emergency ballasts for powering fluorescent lights during power outages that have a reduced profile and do not require a bulky wiring tail. The emergency ballasts may include an external header that is associated with the internal circuitry of the ballast. A connector associated with the wiring of the other lighting fixture components may be inserted into or otherwise connected to the emergency ballast'"'"'s header.
