Each lamp used a standard screw-in bulb, and is suitable for the US power grid after a plug change.We tested the maximum ceiling height at 315 cm for sufficient tension to keep the steel rod in place. Minimum ceiling height 230 cm recommended.Condition: Overall very good vintage condition, ready for daily use.
