The model I do not know, check if the switch has a position on manual and automatic. It may also be a rechargeable flashlight, as a single transistor is displayed. Those that turn off when connected to the network, have 2 transistors. One of them drives when it has network voltage, and cuts off the second one, which turns on the LEDs. When the power is cut off, the first one stops driving, which leads the second and turns on the LEDs.
