Advance HOP2PSP54L35M Electronic Fluorescent Ballast, T5HO Lamp, 54 W, 347 to 480 VAC, Programmed

Our new addition to our high-performance, 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.
