The place you got these lights from looks pretty cool, I'm guessing it's a school of some sort? It seems common in older schools to have one classroom with the original lights but another with updated lights.
It was used as an office for the Natural Gas Pipeline Company of America from the 30s until about 20 years ago. They shut down and boarded it up, and we bought the facility. Super cool history here, lots of Crouse-Hinds industrial lights in the other shop buildings. I'll need to post some of those in the future.
This building was boarded up for 20 years until recently.
