Fluorescents & Wits End...

I've noticed that the contacts in the "tombstones" of the cheap fixtures that I've worked on are made of thin brass. A couple of the fixtures at my church have the "tombstones" pretty much toasted. I decided to buy some spares to repair the fixtures instead of trying to replace the assembly, and noticed that the spares I bought at HD have solid brass contacts about 1/8 inch thick with good springs behind them instead of thin sheet brass!
