Electronic Sign Ballasts
The ideal replacement for obsolete magnetic ballasts.
Keystone electronic sign ballasts have many advantages over magnetic ballasts. They’re more energy efficient, they’re lighter in weight, and – thanks to Keystone technology – they’re far more versatile. We offer two solutions: SmartWire and ParallelWire.
SmartWire
Our SmartWire solution wires exactly the same as traditional magnetic sign ballasts but weighs up to 50% less, making transportation easier. And just three SmartWire ballasts operate all varieties of T8HO and T12HO lamps, helping reduce SKUs and inventory on trucks.
ParallelWire
Our ParallelWire solution ensures that the sign remains lit even when a single lamp fails. It’s also versatile, with just four models able to operate all varieties of T8HO and T12HO lamps.
Quiet operation
No more humming from your magnetic ballasts. Our electronic ballasts are designed for hum-free silence.
