I have an orbit extreme 4 x 130 watt 4 pin flouresent light fixture. It has 2 switches and 2 cooling fans. each bulb has a 120 volt 60hz
ballast. recently one of my
ballast went bad(less than one year). to replace the
ballast with the exact same
ballast costs about $80.00. my question is should I replace the
ballast (current usa brand) one by one as they go bad. or can I upgrade the
ballasts with quality
ballasts like ice cap. anyone done this before? any tips?
