BS 5266 is essential. At Lumenloop, we offer high‐quality, UK‐made emergency lighting solutions tailored to meet these requirements.
Minimum Illuminance Requirements by Location
| Location | Minimum Illuminance (lux) | Uniformity Ratio (Max:Min) | Response Time (seconds) | Minimum Duration (minutes) | Notes |
|---|---|---|---|---|---|
| Escape Routes (Corridors) | 1 | 40:1 | 0.5 | 180 | Measured at floor level along the centreline of the escape route. |
| Open Areas (Anti-Panic) | 0.5 | 40:1 | 0.5 | 180 | Applies to areas larger than 60m². Excludes a 0.5m border around the edge of the area. |
| Staircases | 3-5 | 10:1 | 0.5 | 180 | Enhanced lighting to clearly reveal steps and changes in elevation. Measured on the treads. |
| High-Risk Task Areas | 10% of normal lighting or 15 (whichever is greater) | 10:1 | 0.5 | 180 | Examples include operating machinery, handling hazardous substances. |
Specific Area Requirements
| Area | Minimum Illuminance (lux) | Uniformity Ratio (Max:Min) | Response Time (seconds) | Minimum Duration (minutes) | Reference Plane | Specific Considerations |
|---|---|---|---|---|---|---|
| Kitchens (Commercial) | 15 | 10:1 | 0.5 | 30 | Horizontal on working plane | Focus on cooking and preparation areas; ensure no glare on stainless steel surfaces. |
| First Aid Rooms | 15 | 10:1 | 5 | 30 | Horizontal on working plane | Ensure adequate lighting for examination and treatment; consider colour rendering for accurate assessment. |
| Treatment Rooms | 50 | 10:1 | 0.5 | 30 | Horizontal on working plane | Higher illuminance for detailed medical procedures. |
| Refuge Areas | 5 | 10:1 | 5 | 180 | Horizontal on floor, vertical at communication devices | Ensure clear visibility of communication devices and signage. |
| Plant Rooms (Mechanical/Electrical) | 15 | 10:1 | 5 | 180 | In plane of visual task | Illuminate gauges, controls, and potential hazards. |
| Fire Safety Equipment Locations | 5 | N/A | 5 | 180 | N/A | Includes fire extinguishers, fire alarm call points, and fire hose reels. |
| Reception Areas | 15 | 10:1 | 5 | 180 | In plane of visual task | Provide a safe and welcoming environment. |
| Panic Bars and Security Devices | 5 | N/A | 5 | 180 | Horizontal on plane of device | Illuminate activation points clearly. |
| Swimming Pool Surrounds | 5 | 10:1 | 0.5 | 180 | Horizontal on floor and treads | Consider wet conditions and reflective surfaces. |
| Toilets (Larger than 8m² or Disabled) | 5 | 40:1 | 0.5 | 180 | Horizontal at floor level | Ensure adequate lighting for safe use. |
Frequently Asked Questions
What is BS 5266, and why is it important?
BS 5266 is the British Standard for emergency lighting, ensuring that buildings have adequate illumination in case of power failure.
How long should emergency lighting last?
UK regulations typically require emergency lighting to operate for at least 3 hours in commercial and public buildings.
What is the difference between maintained and non-maintained emergency lighting?
Maintained emergency lighting remains on during normal operation, while non-maintained lighting activates only when mains power fails. Each has its advantages depending on the building's usage and energy efficiency requirements.
How can I ensure my emergency lighting complies with UK regulations?
Ensure your system meets BS 5266 and EN 60598-1 standards. Regular testing and professional maintenance are key, as well as choosing products like those from Lumenloop that have been rigorously tested for compliance.
Why is uniformity important in emergency lighting design?
Uniform lighting ensures consistent visibility, reducing shadowed areas that could hinder safe egress during an emergency.
What are the energy efficiency benefits of LED emergency lighting?
LEDs use significantly less energy, have longer lifespans (up to 50,000 hours), and reduce maintenance costs compared to traditional lighting, making them a sustainable choice for emergency systems.
Can emergency lighting systems be integrated with smart building controls?
Yes, many modern systems—including those from Lumenloop—support DALI, self-test functionality, and other smart controls, allowing for automated testing, monitoring, and efficient management.
How often should emergency lighting be inspected and maintained?
It is recommended to inspect and test emergency lighting at least every month, with full maintenance checks annually, in line with regulatory standards.
