These weigh in at just 4.7kg and with interior LED lights would make a striking centre or mood lighting piece in a home, pub, club, wine-bar or cafe perhaps. With buffing or some fine-grain sanding, the metal will polish to a high sheen, or maybe a neon paint makeover is your style. They could be either wall or ceiling mounted and interior or exterior lit. A fun and unusual conversation piece.
