LED Emergency Backup Driver 20W — 90+ Minutes
Brand: LED Flying Direct
Overview: This 20W emergency backup driver is UL certified, designed to switch an existing LED fixture into emergency mode during a power outage, providing at least 90 minutes of operation. It supports LED fixtures with 0-10V dimming within the 20W to 150W range, including panels and troffers, and can work with fixtures that do not require dimming if under 20W.
Key considerations: UL certification indicates safety and reliability for commercial settings. The driver is suitable for higher-power LED fixtures that still demand emergency support and can be used in dimmable configurations when appropriate.
LEONLITE 8.5W Emergency Driver — 90 Minutes
Brand: LEONLITE
Overview: This unit operates from 120V-277VAC with a 3-60VDC input range, designed for fixtures between 8W and 72W. It includes a rechargeable backup battery delivering approximately 90 minutes of emergency light after full charge (24 hours). It is UL and FCC listed for commercial environments, including hospitals, offices, and shopping centers.
Key considerations: Compatible with troffers and linear fixtures with external drivers; not suitable for T8 tubes with internal drivers. Ensure your fixture falls within the 8-72W range and uses an external driver for proper operation.
LEONLITE 8.5W Emergency Driver (Alternate Model)
Brand: LEONLITE
Overview: Similar to the previous LEONLITE option, this model covers 120V-277VAC and 3-60VDC input with a 90-minute emergency runtime. It is suited for panel, troffer, and linear fixtures that rely on an external driver, with a focus on safe, reliable operation in commercial environments.
Key considerations: Verify fixture compatibility and ensure the external driver configuration is possible with your existing ballast or driver arrangement.
Best BAL500 350-450 Lumens Emergency Ballast
Brand: Best Lighting
Overview: This emergency ballast provides a minimum of 90 minutes of emergency illumination and can be installed inside, on top of, or remotely from the fixture. It supports both switched and unswitched fixtures, increasing installation flexibility for a variety of commercial settings.
Key considerations: Ensure compatibility with 120/277V power systems and check that the ballast can be integrated with your existing fixture configuration and wiring scheme.
Best BAL1400 Fluorescent Emergency Ballast — 90 Minutes
Brand: Best Lighting
Overview: A high-lumen option capable of 1400 lumens with a 90-minute emergency runtime, designed for fluorescent applications in commercial installations. This ballast is suitable where higher emergency illumination is required for fluorescent fixtures and supports 120/277V operation.

Key considerations: Suitable for fixtures that rely on external drivers. Verify compatibility with the LED luminaires and ensure proper wiring for emergency operation under power loss.
Buying Guide: Key Purchase Considerations And Comparisons
When choosing an emergency ballast or LED backup driver, consider these factors to optimize reliability, safety, and compatibility:
- Fixture type and compatibility: Confirm whether your fixture is a panel, troffer, linear light, or T8 tube, and verify if it uses an external driver or internal ballast. Choose devices designed for your specific fixture type and wattage range.
- Voltage and current range: Look for devices that support your mains voltage (120V, 277V, or 347V as applicable) and the lamp wattage range (e.g., 8–72W, 20W, 150W max). Ensure proper integration with existing electrical systems.
- Emergency runtime: Most units provide around 90 minutes of emergency illumination. If longer runtimes are needed, verify product specifications and installation feasibility for your space.
- Certification and safety: UL-listed or UL-certified products indicate adherence to safety and quality standards, which is crucial for commercial and public buildings.
- Dimming and control compatibility: Some emergency drivers support dimming (0–10V) when used with compatible fixtures. If dimming is a requirement, confirm compatibility and performance during emergency operation.
- Installation flexibility: Some ballasts can be mounted inside, on top of, or remote from fixtures. Consider space constraints and wiring practicalities during planning.
- Maintenance and warranty: Review the warranty length and maintenance requirements to ensure long-term reliability and serviceability in a commercial setting.
- System integration: For retrofits, assess how the emergency device integrates with existing ballasts, drivers, or T8 tube configurations to avoid conflicts during operation.
In summary, when selecting an emergency ballast or LED emergency driver, prioritize compatibility with your fixture type, adherence to safety standards, and the required emergency duration. The products listed here provide a range of wattages, voltages, and configurations to support reliable emergency lighting in offices, schools, warehouses, and retail environments.
