The B70A-CAN fluorescent emergency ballast works in conjunction with the AC ballast to convert new or existing fluorescent fixtures into emergency lighting. The emergency ballast consists of a high-temperature nickel-cadmium battery, charger and electronic circuitry in one compact red case. The B70A-CAN can be used with most 17 - 215 W (2’ - 8’) T8, T10 or T12 fluorescent lamps without integral starters, including U-shaped, HO, VHO, circline and energy-saving, and (4-pin) compacts. It is also compatible with most one-, two-, three- or four-lamp electronic, standard, energy-saving and dimming AC ballasts. If used in an emergency-only fixture, no AC ballast is necessary. The B70A-CAN is suitable for indoor locations. It is not suitable for air handling heated air outlets or wet, damp or hazardous locations.
