A method of adding a backup power source to a luminaire that includes exposing driver circuitry through a back surface of a housing for a luminaire having a downlight geometry. The housing contains a light engine that is positioned to emit light through a light emission end of the housing. The driver electronics controls power received by the luminaire for powering the light engine. The method may continue with connecting a battery junction box having an electrical pathway opening in reversible engagement to the back surface of the housing by snap fit engagement. The method may further include connecting a backup battery unit to the luminaire by wiring extending from the battery backup unit through the electrical pathway opening in the junction box to the driver electronics for the luminaire.
