Abstract: Lighting apparatus for improving the efficiency of a fluorescent fixture. A high efficiency reflector having tube hangers depending therefrom is mounted into fixture housing. Substitute fluorescent tubes, one for each original pair of tubes, are mounted under reflectors and held by hangers. A device including a plug and a substitute socket is used to tap electricity from an original fixture socket and to conduct it to the substitute tube through the substitute socket which is itself supported by the substitute tube.
