Electromagnetic

Fluorescent ballast
Circular T12s!

Sometimes the old stuff is impressive in its longevity. Here, found in a stairwell in Olin Science, an old electromagnetic fluorescent 2-lamp ballast from… maybe the early ’60s? It’s got that proper audible-frequency buzz, a housing that looks cast, not extruded, and unless the first one fizzled in the ’70s – entirely possible – this sucker might be original to the building.

One day, it’ll expire, bound for disposal as hazardous waste. (Don’t think too hard about the undoubtedly toxic materials all loaded up inside that little black box.) Until then, it hums and buzzes away in the stairwell, illuminating the space with a pallid, cold glow.

Yeah, nobody misses fluorescent lights all that much.
