Philips Bodine B50 fluorescent emergency ballast works in conjunction with an AC ballast to convert new or existing fluorescent fixtures into emergency lighting. The emergency ballast consists of a nickel-cadmium battery, charger and electronic circuitry in one case. When AC power fails, the B50 immediately switches to the emergency mode, operating either one or two lamps at a reduced lumen output for a minimum of 90 minutes. When AC power is restored, the emergency ballast automatically returns to the charging mode and delays AC ballast operation for approximately three seconds to prevent false tripping of the AC ballast end-of-lamp life shutdown circuits.
B50 Lamp Compatibility:
Initial Lumen Output
Number of Lamps
Lamps by Wattage
