This versatile emergency lighting is suitable for both recessed and surface-mounted, so you decide what suits you best. The lamp illuminates both included pictograms and the surrounding area, with additional light downwards for excellent visibility up to 30 meters. In the event of a power outage, the 1500mAh battery provides bright white light (6000K) and 100 lumens per watt for three hours. Thanks to the automatic test function, the lamp checks itself regularly, and an LED indicator makes it easy to see whether maintenance is needed.
