Restoration Hardware’s 1920s German Light Bulb Voltage Tester Bar was inspired by an original light bulb voltage tester that was salvaged from a factory in Germany. This steampunk-like bar is fashioned from iron and weighs 265 pounds. The sphere opens up into a bar featuring three shelves, three stemware racks, and five slots for wine bottles.
The 1920s German Light Bulb Voltage Tester Bar costs $1,995 and can be purchased from Restoration Hardware’s website.
