“Sector Flux” is a new concept proposed for the theoretical treatment of long linear sources, such as fluorescent lamps mounted end to end. Its measurement is discussed and a method employing parallel mirrors is described.
This treatment permits prediction of the light distribution from linear installations, based on measurements made on a single fitting in the laboratory.
