Product Information
The Kosnic Nitro Surface 2 Duo Emergency Downlight (2.5W, Manual & Self-Test) is a compact, surface-mounted safety fixture designed to provide a simple and reliable emergency lighting solution. Operating as a non-maintained unit, this efficient 2.5W downlight remains on standby during normal building operations and activates automatically the moment a power outage occurs.
Equipped with long-lasting internal LiFePO4 batteries, the Nitro Surface 2 Duo ensures an uninterrupted 3-hour backup power supply to keep escape routes and commercial spaces safely illuminated during an unexpected power cut. Because it is a surface-mounted unit, it eliminates the need for recessed cutting, making installation straightforward on a variety of ceiling types. To streamline building safety compliance and simplify routine facility maintenance, this advanced model features integrated dual-testing intelligence, allowing for both convenient manual checks and automated self-testing diagnostic routines.
