LED Emergency Backup Driver 20W by LED Flying Direct
This 20W emergency backup driver is UL certified, ensuring quality and safety. It switches to emergency mode during power outages and keeps existing LED fixtures illuminated for at least 90 minutes. Best for LED panels, troffers, and similar fixtures with input power between about 20W and 150W, including some non-dimmable configurations. Choose this if you need robust protection for office or retail lighting systems with a compact form factor.
Best for customers prioritizing safety certification and a straightforward installation path. Beware that high-wattage fixtures near the upper limit of its range may require compatible dimming or ballast considerations.
Who this is for: facilities needing dependable backup lighting for 0/1-10V dimmable fixtures or non-dimmable tubes in a compact unit.
Bodine BSL310 Emergency LED Driver
Designed for linear LED strips, this 10-watt emergency driver delivers 90 minutes of illumination and uses a Class 2 output. It’s well suited for offices or hallways with long, linear lighting runs. Best for retrofit projects where slim form factors simplify installation in existing fixtures. Use this instead of bulkier drivers when space is limited.
Best for: linear strip projects that require a compact, reliable 90-minute emergency option. Limitations: only 10W output makes it less suitable for higher-wattage LED runs without additional power management.
dephen Emergency T8 LED Tube 4ft with Battery Backup
This 4ft T8 tube combines a regular G13 LED tube with built-in emergency lighting. It outputs 2200 lumens in normal operation and provides 960 lumens for backup for over 90 minutes. Best for retrofits where bypassing existing ballast is feasible. Suitable for shops, warehouses, or offices upgrading old fluorescent systems.
Best for retrofits where ballast bypass is already planned. Caution: double-ended tubes may require compatible wiring and ballast removal prior to installation.
Bodine BSL310PC Emergency LED Driver
Configured for linear LED strips with a 120/277V input, this emergency driver provides a 90-minute illumination window. It shares Bodine’s reputation for durability in commercial lighting applications and integrates well with linear fixtures across large spaces. Choose this when your installation spans multiple fixtures on a single circuit and you need uniform emergency lighting.
Best for: linear strip systems in 120/277V environments. Limitation: 90-minute runtime might be insufficient for longer outage events without additional battery capacity.
Iota ILB CP10 HE Emergency Driver
The ILB CP10 HE is a constant-power emergency LED driver rated at 10W, designed for class 2 luminaires. It switches to emergency mode after a power outage and provides 90 minutes of operation. The unit includes a charger and converter in one compact enclosure, with multiple mounting configurations. Best for compact fixtures needing reliable, steady power during outages.
Better for: small fixtures where space is at a premium. Caution: 10W output limits its use for higher-wattage LED arrays unless paired with other drivers.
E2 Lighting 4ft T8 LED Tube with Emergency Battery (5 Pack)
These ballast-bypass T8 tubes include an emergency battery and offer 5 CCT tunable settings from 2700K to 5000K. With 6W operation in emergency mode and 120-277V compatibility, they suit office and warehouse environments needing consistent emergency lighting. The five-pack option supports larger installations with uniform color temperature and backup performance.
Best for: multi-fixture installations requiring tunable colors and integrated backup. Limitation: ballast bypass is needed, which may complicate some retrofits.
BatteryGuy FBP-2-40H Replacement Ballast
The BatteryGuy replacement ballast provides a dual 120/277V voltage option and a robust internal transfer switch that connects the battery to fluorescent lamps for at least 90 minutes of emergency illumination. This option is suitable when upgrading existing fluorescent systems to sustain operation during outages. Best for: facilities with hybrid lighting needs and older fluorescent setups.
Limitation: designed to support fluorescent technology; may require adaptation for purely LED fixtures.
Buying Guide: Key Considerations for Emergency Lighting Solutions
What type of fixture needs backup power? LED panels, troffers, tubes, and linear strips each have different electrical requirements. Identify the fixture type and the maximum wattage to select a compatible emergency driver or ballast.
How long should the backup last? Most options provide around 90 minutes, which is standard for safety codes in many spaces. If longer outages are possible, consider higher-capacity units or modular configurations that can extend illumination time.
What voltage and circuit conditions apply? Common ranges include 120V, 277V, and 120/277V multi-volt designs. Ensure the chosen device matches your supply and that it can operate in your building’s electrical environment.
Is ballast bypass required? Some T8 tubes and ballast bypass tubes require bypassing existing ballasts for proper operation. Plan for wiring changes and check compatibility with other fixtures in the system.
Safety certifications and warranties matter. Look for UL or equivalent listings to ensure compliance with electrical safety standards and reliable performance over time.
Ease of installation and mounting options can affect project timelines. Compact enclosures, flexible mounting, and simple wiring help speed up retrofits in tight ceilings and soffits.
