Overview

Electronic Battery Ballasts

In addition to its well known electronic ballasts, ARRI has developed several DC ballasts: 125/200W, 200/400W and 575/1200W. The two smaller units can be combined with battery belts for use as portable daylight systems. The bigger 575/1200W DC ballast is often used where no AC public net is available.
