ELE BALLAST (4) 49W T5HO 347-480V by Signify Electronics

High performance for high ceilings Optanium High-Efficiency Design - T5HO version reduces input watts for additional energy savings over Centium T5HO Ballasts;Independent Lamp Operation - Helps reduce maintenance costs as more lamps remain on when lamps reach end-of-life minimizing wasteful re-lamping;Fast Programmed Starting. - Lamps start in less than one second, improving lighting system response to occupancy sensors Our new addition to our high-performace, high efficiency Optanium ballasts family, these new programmed start parallel ballasts for T5HO lamps are now available as parallel-wired which provides independent lamp operation within the fixture. When one lamp reaches its end-of-life (EOL) the remaining lamps stay illuminated, which means you change out only the lamps that need to be replaced. IntelliVolt Technology (120-277V);Lamp EOL Protection;UL Type CC rated - Anti-arcing circuitry provides greater flexibility to meet end-user application requirements Warehouses, offices, classrooms, workshops, low bay retail, restaurants
