The EB7T5 fluorescent emergency ballast works in conjunction with the AC ballast to covert new or existing fluorescent fixtures into emergency lighting. When AC power fails, the EB7T5 immediately switches to the emergency mode, keeping one lamp illuminated at a reduced lumen output for a minimum of 90 minutes. When AC power is restored, the ballast automatically returns to the charging mode.

The EB7T5 has been tested in accordance with the standards set forth in UL 924, “Emergency Lighting and Power Equipment,” and is UL Listed for factory or field installation. Emergency illumination time exceeds the National Electrical Code (NEC), Life Safety Code (NFPA-LSC) and UL 90-minute requirements. It can be used with one 14W through 54W (2’-4’) T5 fluorescent lamps, 17W through 40W T8 lamps without integral starters, and 17W through 55W 4-pin long compact lamps. It is also compatible with most electronic and dimming AC ballasts.

The EB7T5 uses a specially constructed, high-temperature nickel cadmium battery. It produces 800 lumens initial emergency light output. 120/277 VAC input. Single pole test switch. 24 hr recharge time. 0ºC to 55ºC ambient temperature rating.
