Keystone’s electronic sign ballasts are the ideal replacement for obsolete magnetic ballasts.

Menu

In 2014, the Department of Energy outlawed magnetic sign ballasts due to their inefficiency. Electronic sign ballasts have many advantages over magnetic ballasts in addition to their energy savings. To make upgrading to an electronic ballast as easy as possible, Keystone offers two solutions: Smart Wire and Parallel Wire.

Benefits of Smart Wire

  • Wires exactly the same as traditional magnetic sign ballasts for seamless compatibility and installation
  • Weighs up to 50% less than magnetic ballasts, making transportation easier
  • Exceeds the energy efficiency levels mandated by the DOE and are at least 10% more energy efficient than magnetic ballasts
  • Reduces inventory with the versatility of just 3 Smart Wire ballasts to operate both T8HO and T12HO lamps
  • Eliminates the humming generated from magnetic ballasts for a quiet operation

Benefits of Parallel Wire

  • Ensures the sign remains lit even when a single lamp fails
  • Reduces inventory with the versatility of just 4 parallel wire ballasts to operate both T8HO and T12HO lamps
  • Maximizes energy efficiency
  • Eliminates the humming generated from magnetic ballasts for a quiet operation
  • Wires more easily than other sign ballasts
