Emergency battery back-up drivers convert standard LED fixtures into code-compliant emergency egress lights without requiring a separate dedicated emergency luminaire. When utility power is interrupted, the driver switches to battery mode and powers the LED array for the 90-minute minimum illumination period required by NFPA 101 and the International Building Code. This approach simplifies the lighting layout because a single fixture handles both normal and emergency operation, reducing fixture count and wiring runs compared to a traditional emergency fixture strategy.

Emergency LED drivers are available in fixed-wattage and field-adjustable wattage versions. Fixed-wattage units power the full LED load in emergency mode, while adjustable units allow the installer to set a lower emergency wattage that extends battery runtime. Most units include a self-test function and a visible indicator LED for monthly and annual testing compliance required by the NEC. Battery chemistry is typically sealed lead acid or nickel-metal hydride, with service life ratings that should be factored into the maintenance plan.

Browse all driver types in the LED Drivers category. For primary (non-emergency) LED drivers, see Constant Current LED Drivers and Constant Voltage LED Drivers. For fluorescent emergency ballast options in retrofit or legacy applications, our Fluorescent Emergency Ballasts section has stocked inventory. Contact RelightDepot for emergency driver spec support and code compliance guidance.
