LED emergency modules are essential, battery-backed components that allow LED fixtures to provide 3 hours of illumination during power failures. They are compatible with various LED drivers (3-55V or 110-240V) for commercial, residential, and industrial applications. These units feature automatic, often “plug-and-play” installation, with Ni-Cd or NiMH batteries and deep discharge protection.

Key Features and Details

Functionality: They provide emergency lighting for 3 hours, with a full charge usually taking up to 24 hours.

Compatibility: These modules work with many LED drivers, including those for T8 tubes, panels, and bulkheads.

Installation: They are designed for easy integration, with options for within-luminaire or ceiling-void placement.

Safety Features: They often include deep discharge protection and green status LEDs to indicate charging or testing.

Compliance: Many models are designed to meet UK safety regulations.

Types: Available for both maintained (stays on when power fails) and non-maintained (only turns on when power fails) systems.
