This is a Regent 175 watt Mercury Vapor yard light fixture that used to be outside my Uncle's garage. The ballast it originally came with had since developed a loud buzz (it could double as a door-bell buzzer) so we replaced it with a spare Lithonia brand yard light.
I kept this fixture with the intention of converting it to an M57 ballast so it can run both 175 watt probe-start Metal Halide and Mercury Vapor lamps
