Buy a new ballast based on the type and number of bulbs your fixture holds, as well as on the ballast factor and the sound rating,
Luminaire, 250 Watt High Pressure Sodium, Multitap Wire For 120 Volt, Prismatic Refractor, Copper Wound Ballast With High Power Factor, Lead Type, And Low Loss Lead Ballast Factor Of "1", Rated 40 Degrees C Ambient And Suitable For Use In Wet Locations.
Other examples may include minimum luminaire efficiencies or a certain ballast factor for an electronic T8 ballast.
Electronic ballasts can be classified by starting method (instant or programmed rapid start) or light output, which is measured and reported as ballast factor. The high-efficiency electronic ballasts offer two ballast factors options: 0.78 and 0.88.
When I see absolute requirements for a 1.14 ballast factor for an energy saving lighting change-out--regardless of the ceiling height--I shudder.
Ballast factor (BF) -- the ratio of the light output of a lamp operated by a given ballast to the light output of the same lamp when operated by a reference ballast.
