How can I tell if a ballast manufactured by GE contains PCBs?
All high-power-factor fluorescent lamp ballasts manufactured by GE Lighting prior to May 1977 include a small metal capacitor (an electronic device used to store an electrical charge) that contains approximately 10 grams of PCB fluid. The capacitors in our fluorescent lamp ballasts manufactured after January 1, 1979, do not contain PCBs. Ballasts manufactured between May 1977 and January 1, 1979, may include either type of capacitor.
