Advance introduces a complete family of Low Profile, T8 Centium ballasts incorporating IntelliVolt technology. IntelliVolt permits inventory and SKU reduction throughout the supply chain, since the same ballast can operate on any system voltage from 120 to 277 volts, AC/DC 50/60Hz. These IntelliVolt ballasts are featured in our industry standard small housing package. These low profile, lightweight units are ideal for the new generation of low profile fixtures. The ballasts have the same wiring configuration and mounting dimensions as standard size ballasts, and are therefore ideally suited for retrofits into existing fixtures.
