The Galaxy 3.3 system has an additional feature that is extremely useful in case of power outages. The RDL0013-3 lamp in this configuration is equipped with a Schuko connector and a built-in battery. Power support allows operation after the mains power is cut off for more than an hour. In power backup mode, the luminous flux will be lower (1,000 lm), which still provides visibility and illumination in emergency situations. When mains power is restored, the lamp automatically returns to its standard output parameters, ensuring continuous lighting. The model with backup while plugged in has a luminous flux of 4100 lm.
