Ceiling surface mounting reduces installation complexity and time, enabling faster project completion and neater cabling in corridors and open spaces. The business impact is a lower labor cost and lower risk of retrofit disruptions, making it ideal for retrofit and new-build applications in offices, factories, and retail facilities. The non-maintained NM mode ensures the luminaire only operates during power loss, avoiding unnecessary drain while guaranteeing emergency readiness when it matters most. The device utilizes a peripheral (individual) battery with 3.2 V lithium-ions, supporting predictable autonomy and easy compatibility with standard UPS and safety back-ups. This translates to fewer on-site battery replacements and a clear path to compliance with life-safety requirements. With 150 lm output at 5700 K, the focal lens provides focused egress illumination that aligns with modern illumination standards and occupant safety expectations. The design also emphasizes energy efficiency with LED-based performance rated A++ to A, reducing operating costs over the life of the installation. Plug-in connection and 2.5 mm2 conductor cross section simplify wiring and inventory management, while the IP44 protection rating ensures suitability for indoor damp locations and open-plan spaces. The unit’s compact 138 mm diameter and white plastic housing integrate discreetly into most ceiling silhouettes, improving aesthetics without compromising performance. Rated life times of up to 60600 hours demonstrate the long-term reliability expected in critical safety applications, delivering a strong return on investment through reduced maintenance and replacements. The product’s 3-hour autonomy, crystal-clear white light, and robust build quality make it a practical solution for open-area lighting and open-concept workspaces where safety and reliability cannot be compromised.

FAQs

Installation uses a plug-in connection for rapid wiring and a ceiling surface mounting method. The unit operates on 230 V AC and requires a 2.5 mm2 conductor cross section. Its compact 138 mm diameter fits standard ceiling canopies, simplifying retrofits and new installs in offices and industrial spaces with minimal tools and time.
Key specs include 150 lm output at 5700 K, IP44 protection, non-maintained NM operation, and a 3-hour autonomy with a 60600 hour rated life. The combination ensures reliable emergence lighting during outages, compliant with typical safety standards, and low maintenance due to long LED life and non-exchangeable lamp design.
Yes. Its IP44 rating, ceiling surface mounting, and 3-hour autonomous operation make it suitable for escape routes and open areas in factories, warehouses, and large offices. The white plastic housing blends with industrial interiors, and the rugged IK04 impact rating supports busy environments where durability matters.
The unit carries CE certification and IP44 protection, aligning with common European safety and performance requirements for emergency luminaires. Glow wire resistance to 850 °C and a long service life further support regulatory compliance and risk management in critical safety applications.
With a long rated life of up to 60600 hours and LED-based construction, maintenance is minimal since the lamp is not user-exchangeable. The 3-hour autonomy reduces downtime during outages, and the plug-in wiring lowers installation costs, delivering a favorable ROI through lower labor, fewer replacements, and reliable performance over time.
