The self-sufficient emergency light features an LED light source. The operational duration can be selected via a switch (1 h, 2 h, 3 h, 8 h). The luminous flux varies according to the selected operational duration (261 lm at 1 h, 233 lm at 2 h, 192 lm at 3 h, 70 lm at 8 h). The emergency light is equipped with a monitoring module for automatic function and duration tests to ensure operation according to DIN V VDE 0108-100-1 and DIN VDE 0711-400. The status indication (ready for operation, charging, battery operation, battery fault, LED/electronics fault) is provided by a two-color status LED.
