ballasts

[Jamesfish10]

Hi, I'm new to this forum and was wondering if anybody got any ideas of such tests we can do on starter type ballasts? To determin whether there good or bad??

It's a nightmare in outside lights up high when ballast blows and takes out all lights , sort cables in contactor, changing one at a time then eventually split the circuit and work from there, sometimes over the years they just add into out going side of contactor , sick of lights lol

Many years ago, we got so fed up with this that we started a program of fitting internal in-line fuses to every hi-bay fitting across all our warehouses. Was very satisfying when someone would report one unit had gone down rather than a whole phase.
