The ballasts in the Peerless fixtures.

Out of the three, the Philips ballast is the only one that's original to its fixture, and it's in pretty rough shape. Some tar has leaked, the sticker cooked from the heat. I suppose those three fixtures were in a high ceiling or something like that, so the ballasts had to endure pretty high temperatures. One of the Philips withstood the heat all those years, but the other two didn't LOL.

The three striplights are still untested as I type this.
