In mode C of the Brennenstuhl solar LED wall light (800 lm, IP65), the lamp automatically switches on at full brightness (800 lm) when movement is detected, but this only happens when the ambient light is low, i.e. in the evening or at night. The lamp is fitted with a day/night sensor that prevents it from being switched on during daylight hours when there is sufficient natural light.
The article has two batteries that are replaceable. In addition, this article has 3 modes.
Mode A automatically turns on at dusk, stays on at 20% brightness for up to 5 hours and then turns off. The information about the 24 hour battery life is wrong and will be changed soon. 24 should be months and refers to the warranty.
The statement about the battery life (24 hours) is also correct because the battery works even when the light is not used. In addition, the batteries are constantly recharged by solar energy. Therefore, the battery life is 24 hours.
