Emergency ballasts for T12, T8 and T5 linear fluorescent fixtures continue supplying power to the fluorescent lamps when there is a loss of power to the circuit. Like any linear fluorescent electronic lighting ballast, during normal operation, emergency ballasts limit the voltage or current across the lamps, preventing the lamps or circuits from failing.

Throughout regular operation, a battery built into the ballast maintains a charge. During an outage, the battery in the emergency ballast keeps the fluorescent tubes illuminated for 90 minutes or more. Emergency ballasts are rated to supply a consistent lumen output off the battery power, ranging from 300-500 lumens on the low end all the way up to 3000 lumens on the high end.

Linear fluorescent emergency ballasts are essential for security and life safety in a commercial lighting application. You can select standalone emergency ballasts from our inventory, or choose a complete linear fluorescent emergency ballast retrofit kit for your installation.
