Emergency lighting that organises itself
A compact emergency downlight combines a replaceable LiFePO4 battery with KeiltonEM. According to the product announcement, up to three hours of emergency operation are possible.
Discreet in the ceiling, 500 lumens when it matters
In normal operation the Series 19 recessed downlight is barely visible: 55 millimetres cut-out diameter, 38 millimetres deep. When the power fails it delivers 500 lumens and keeps the escape route lit for up to three hours – at 3 watts and 167 lumens per watt in 5,000 kelvin.
The optic can be changed. 135 × 55 degrees sends the light along the length of the escape route, 140 degrees lights open areas evenly. Which one fits is decided by the geometry of the room, not by the catalogue.
No central battery system
The battery belongs to the device. That saves the central battery system and the fire-resistant wiring – two items that often cost more in a retrofit than the luminaires themselves. Suspended ceilings, existing corridors, refurbishment during operation: everywhere there it counts that only an ordinary supply line is needed.
Testing without climbing a ladder
The system reports by itself. Function tests run automatically, the status can be read in real time, and the test log can be exported as a file or sent by e-mail. How often testing is required and what belongs in the log is set out in the guide to testing emergency lighting.
For maintenance and recurring tests there is NOTLUX – our brand for exactly that part.
