Will these ballasts work

[Shadetree]

Thanks Victor, I will try it out. That is great news for the pc ballast though for me [img]images/smiles/icon_smile.gif[/img] I also have about 50-70 22" pc bulbs that fit your exact description with the four inline pins, 40 watt, 4000K they are 22". They will not fit my fixture here but if anybody is interested in one let me know.
