The following sections profile five options that are commonly chosen for LED compatibility, ease of installation, and reliable backup performance. Each section provides a concise overview, relevant features, and practical considerations for choosing the right ballast for your fixtures and space.
BAL700 Emergency Lighting Ballast
The BAL700 provides dual 120/277-volt compatibility, aligning with newer lamp technologies and potentially extending lamp life. Its internal solid-state transfer switch automatically connects the internal battery to connected fluorescent lamps to deliver a minimum 90 minutes of emergency illumination. This design supports both retrofit and new installations where higher voltage flexibility is beneficial, reducing the need for separate ballast inventories in mixed-technology environments.
Bodine B90 Emergency Linear Fluorescent Ballast
The Bodine B90 ballast delivers a 90-minute emergency operation with a simple, compact design suitable for linear fluorescent fixtures. It includes a single-pole test switch and a visible LED charging indicator to monitor battery status. This option is a practical choice for standard office or corridor luminaires where straightforward testing and reliability matter most.
Emergency T8 LED Tube With Battery Backup
This dephen 4-foot tube combines a regular G13 T8 LED with built-in emergency functionality. It emits up to 960 lumens of emergency light for over 90 minutes, making it suitable for retrofitting existing fluorescent fixtures. Installation requires bypassing the ballast, and the unit operates on 100–277 VAC. It is particularly advantageous for retrofit projects where preserving fixture aesthetics and minimizing downtime is important.
Best Lighting BatteryGuy Replacement Ballast
The BatteryGuy replacement ballast offers dual 120/277 voltage with AC output for compatibility with newer lamp technologies and to support extended lamp life. An internal solid-state transfer switch ensures the internal battery supplies the lamps for at least 90 minutes during an outage. This option is well-suited for facilities seeking robust, plug-in compatibility across a range of fluorescent systems while maintaining emergency resilience.
BAL500 350 to 450 Lumens Emergency Ballast
The BAL500 ballast provides 350 to 450 lumens of emergency lighting with a minimum of 90 minutes runtime. It supports installation inside, on top of, or remote from the fixture and works with both switched and unswitched configurations. This flexibility makes it a practical option for settings where fixture placement or wiring constraints vary widely, such as multipurpose rooms or retail spaces.
Bodine LP600 Linear Fluorescent Emergency Ballast
The Bodine LP600 is a specification-grade, low-profile emergency ballast intended for standard and high-output T5 and T8 lamps. It emphasizes high lumen performance and is suitable for commercial environments that require consistent emergency illumination without compromising fixture aesthetics or ceiling profiles. This option is often chosen in spaces demanding durable, code-compliant emergency lighting solutions.
Buying Guide: Key Purchase Considerations
- Runtime and battery type: Most units provide 90 minutes of emergency light. Verify whether the ballast uses a sealed lead-acid or lithium battery and confirm expected lifecycle and replacement intervals.
- Voltage compatibility: Choose a ballast that supports the voltages in your building (common options include 120V and 277V). Dual-voltage models simplify inventory for mixed lamp installs.
- Compatibility with lamp types: Confirm whether the ballast supports the specific lamp types in your fixtures (LED retrofits, fluorescent tubes, T5/T8 configurations). Some options are designed for retrofits as well as new installations.
- Installation and wiring: Determine whether the ballast requires ballast bypasses or can operate with existing wiring. Consider whether a remote or inline installation suits your ceiling layout and access.
- Testing and indicators: Built-in test switches and LED indicators simplify maintenance. Look for units that simplify monthly or annual testing as required by local codes.
- Physical dimensions and form factor: Low-profile or compact designs fit in tight fixtures. Ensure the unit fits within the luminaire or fixture canopy without impeding airflow or service access.
- Compliance and certifications: Verify UL or equivalent certifications for safety and compliance with local building and fire codes.
- Lifecycle costs: Consider upfront cost, expected lamp compatibility, and replacement interval for batteries to assess total cost of ownership.
- Brand and support: Reputable brands with clear warranty terms and accessible technical support simplify procurement and maintenance.
For facilities managers evaluating emergency lighting upgrades, a balanced approach considers runtime reliability, compatibility with current fixtures, and ease of maintenance. When retrofitting older fluorescent systems with LED-compatible backups, assess whether a direct retrofit ballast or a tube-with-backup approach provides the best long-term value and service continuity.
