Emergency LED Tube Lights: Battery Backup for Safety Lighting
An emergency tube light features a built-in battery that automatically activates when normal power fails. These specialized lamps include T8 tubes and T10 formats, combining everyday overhead illumination with battery-powered backup. The integration of the battery backup light bulb directly into the tube eliminates the need for a separate external emergency battery pack.
Key Features of Emergency LED Tube Lights
These tubes provide backup illumination when normal power is lost.
- Integrated Battery Backup: The LED tube with battery contains its own power source, with designs providing 90 minutes of illumination during an outage.
- Emergency Light Output: Battery operation supplies reduced output, such as 400 lumens from a tube producing approximately 2,100 lumens during normal operation.
- Fluorescent Retrofit: A ballast-bypass emergency tube light replaces the fluorescent lamp and operates without its ballast, using the specified direct-wire connections.
- Automatic Activation: The battery powers the emergency T8 or T10 light source when normal power fails, providing backup safety lighting.
Emergency Tube Light Applications
Emergency tubes support backup illumination in commercial and public interiors during power outages.
- Primary Use: Provides backup safety lighting for circulation areas and exit routes as part of the building’s emergency lighting design.
- Hospitals and Schools: Supports visibility in corridors, stairwells, and common areas during power outages.
- Tube Formats: T8 and T10 designs can use a G13 medium bi-pin base. Ballast Bypass (Type B) operation requires direct-wire installation.
- Charging: The LED tube with battery uses its AC supply to recharge the battery, with 120–277V designs supporting common commercial supply voltages.
Emergency Tube Lighting Retrofit Solutions
Emergency tube lights combine normal illumination and battery backup within a linear lamp. A battery backup light bulb provides one approach within a broader safety lighting system.
