Maintained low-power LED emergency equipment provides continuous illumination, acting as standard lighting, while automatically switching to battery power during outages. These highly efficient, low-energy units (often <5W for bulkheads) feature long-lasting LEDs, reducing energy costs and maintenance, with 3-hour backup durations.

Key Aspects of Maintained Low-Power LED Emergency Equipment:

Operation: They remain illuminated at all times, using the same LEDs for normal and emergency power.

Low Power Consumption: LED technology allows for significantly reduced energy consumption compared to traditional fluorescent, often keeping consumption below 5W in bulkhead scenarios.

Automatic Switching: Integrated high-temperature battery packs (NiCd or NiMH) and intelligent chargers automatically activate during power failure.

Applications: Ideal for public areas, cinemas, shopping centers, and exit routes where constant illumination is required for safety.

Testing and Control: Often available with DALI (Digital Addressable Lighting Interface) or self-test functionality, allowing for efficient monitoring and compliance checks.

Flexibility: While designed to be maintained, many units can be wired as non-maintained if necessary.

Lifespan: The LEDs used often last for the entire lifespan of the device, cutting down on maintenance costs for bulb replacements.
