Self-Contained Emergency Light Luminaires
The MEM209CD2 self-contained emergency light has a modern and compact design with special functions not available in other units. It has both a motion and a light sensor to provide maximum functionality for the user for multiple use cases. During power outages the unit will provide illumination using battery power. During normal power conditions, if the surrounding area is dimmer than 5 Lux and the unit detects a person walking by, it will automatically provide illumination using mains power and will turn off automatically after 15 seconds when there is no one left in the area. This extra functionality can be enabled or disabled by the user.
The casing is produced from 1mm thick Electro-Galvanized steel coated with Epoxy powder and special chemicals to prevent any rust from forming.
