IP44 protection and IK04 impact resistance shield the luminaire in corridors and open areas, while the white plastic housing maintains a clean, unobtrusive profile in busy interiors. The round form factor with a 138 mm diameter and 48 mm height simplifies ceiling surface mounting and field installation. A sealed 3.2 V Li-ion battery provides reliable 3 h autonomy and a 60,600 hour life, reducing maintenance visits and downtime. Electrical performance is optimized for low-energy emergency lighting: 230 V AC, max 0.2 W system power, apparent power 0.4 VA, and a PF of 0.45, with a plug-in connection that eases wiring. Light output is 150 lm at 5700 K with CRI ~70, delivered via a focal lens for effective egress. The unit uses a single LED head, requires no external control gear, and remains cost-efficient and dependable over the product life. Durability is reinforced by CE marking for indoor use and a glow-wire test of 850 °C, suitable for retrofit projects and new installations in indoor escape-route lighting schemes.

Connect to 230 V AC supply, ensure indoor use (IP44) and follow the manufacturer’s mounting guidelines. The compact 138 mm diameter and 48 mm height fit standard ceilings, and no separate control gear is required, simplifying retrofits and new installations.
Key specs include 230 V AC operation, 0.4 VA apparent power, PF 0.45, max system power 0.2 W, 150 lm lumens at 5700 K, CRI ~70, 4 LEDs, and a 3 h autonomy with Li-ion battery (3.2 V). It uses a single LED head, is indoor-only (IP44), and has a rated life of about 60,600 hours L70/B10 at 25 °C.
Yes, it is designed for indoor escape-route lighting in corridors, stairwells, and open indoor areas. It is IP44 rated for indoor protection, Non-Maintained mode, and does not require outdoor installation or explosion protection, making it appropriate for controlled indoor environments where safety lighting is essential.
The unit carries CE certification for indoor safety and performance. Its IP44 protection and IK04 impact rating signal robust indoor reliability. Glow-wire performance up to 850 °C further supports fire-safety compliance in evacuation lighting. While CE and IP44 are explicit, additional third-party ENEC or similar certifications may be available through Eaton documentation for particular regions.
With a non-exchangeable LED source and a long-life Li-ion battery rated at roughly 60,600 hours, maintenance intervals are minimal. The compact, plug-in wiring simplifies installation and reduces labor costs. A 3 h autonomy ensures occupant safety during outages, contributing to lower downtime risk and a favorable return on investment over the product lifetime.
