LED backup lighting has become widely adopted for its energy-saving features, low maintenance, and stable performance during power failures.
Why LED Emergency Lighting Makes Sense for Fire Systems
When the mains power fails, well-placed LED emergency fittings illuminate escape routes, helping occupants exit the premises safely.
Unlike older fluorescent lights, LEDs switch on instantly and maintain steady light, which is essential during emergencies.
LEDs also hold their brightness and hue consistency across their operating life, reducing lighting variations in areas such as stairwells and corridors.
Why LED Emergency Fittings Are a Sensible Update
Many facilities still use legacy emergency lights with incandescent or fluorescent technology, which wear out quickly and consume more power.
LEDs are engineered to last thousands of hours, with limited output degradation. This helps facility managers manage upkeep more effectively.
Although emergency fittings are mainly idle, energy consumption during charging and testing still contributes to overheads. LEDs have lower consumption, keeping operating costs lower over time.
Their solid-state design also withstands temperature changes and routine checks, reducing the risk of failure due to lamp faults.
Main Types of LED Emergency Lighting
- Maintained fittings: Remain on under normal conditions and remain active during power loss. Used in public venues.
- Non-maintained fittings: Illuminate solely when mains power is lost. Suitable for workplaces.
- Exit signs: LED exit signage ensures directional clarity even in dim conditions. These are essential in regulated fire safety plans.
- Bulkhead lights: Designed for tough environments, bulkheads are durable and ideal for outdoor stairwells.
Installation & Testing for Compliance
To ensure reliability from LED emergency lights, proper installation and routine testing are necessary.
Adherence to BS 5266 is recommended to ensure appropriate positioning near emergency exits, equipment stations, and hazard areas.
Many LED units now include automated diagnostic functions that track battery health, reducing the need for manual testing and supporting maintenance planning.
Advantages for Facility Managers & Occupants
LED emergency lighting contributes to secure evacuation procedures and predictable servicing. Their compatibility with existing fire systems makes them a sensible upgrade.
Lower power consumption also supports environmental goals, while consistent operation during mains failure enhances readiness in emergency planning.
FAQs
- How long do LED emergency lights last?
- Well-built LED fittings typically last several years before component servicing is required.
- Do they need specialised installation?
- Yes, a qualified professional should install them in line with BS 5266 to ensure compliance.
- Can they be used with older systems?
- Many LED models are designed to connect to existing wiring and control setups, though system matching should be confirmed in advance.
- Are self-test fittings worthwhile?
- Yes, they streamline maintenance and are particularly useful for sites with infrequent inspections.
- What brightness is appropriate for escape routes?
- Reputable fittings meet the regulatory thresholds for emergency illumination without the need for manual adjustment.
