DF168H Model Compact Emergency Backup Driver for 9–20W T5/T8 LED Tubes
Upgrade your commercial lighting with our high-efficiency Emergency Backup Driver for T5 and T8 LED Tubes, specifically engineered for 9W–20W retrofit applications. Delivering 100% full-power emergency output, this driver ensures zero drop in brightness during sudden power outages, maintaining critical visibility when safety matters most. Designed with an ultra-compact profile, it fits seamlessly into standard tube light fixture channels, making it the ultimate solution for upgrading traditional fluorescent fixtures to code-compliant LED emergency lighting. It flexibly powers either single-tube or dual-tube setups and fully supports motion-sensor integrated tubes—delivering 100% brightness during occupancy and energy-saving dimming during standby. It is ideal for underground parking garages, stairwells, office corridors, warehouses, and commercial retrofit projects.
Description
Key Features
100% Full-Power Emergency Output
Unlike standard emergency ballasts that reduce lumen output during outages, this driver maintains full 100% brightness for 9W–20W LED tubes, guaranteeing uncompromised visibility and life-safety compliance.
Single & Dual-Tube Versatility
Offers dual-compatibility wiring, allowing a single emergency unit to power either one LED tube or two tubes simultaneously for flexible installation options.
Ultra-Slim & In-Fixture Mounting
Engineered with a low-profile housing designed to fit directly inside standard T5/T8 luminaire wireways and batten channels, keeping installations clean and external wiring hidden.
Ideal for Fluorescent-to-LED Retrofits
Simplifies commercial retrofit upgrades by converting existing fluorescent troffers, strip lights, and linear fixtures into compliant emergency lighting without replacing the entire housing.
Sensor-Compatible & Smart Energy Savings
Fully compatible with microwave and PIR motion-sensor LED tubes-supporting auto-dimming during idle hours and ramping up to full output when motion is detected during standard operation.
Broad Commercial Applications
Perfect for 24/7 operating environments and code-required emergency routes, including underground parking structures, stairwells, hallways, warehouses, office buildings, and retail facilities.
