The Plasma Ball makes for the ultimate iconic indoor lighting and features two different modes. The Plasma Ball by RED5 can be switched permanently on or set to 'sound responsive' mode in which the globe illuminates in time with the music, creating the ultimate party effect! Placing your hand on the globe attracts the ignited plasma but don't worry its completely insulated so you don't feel a thing. It's one of those things that you simply can't stop touching!
