Plug in wall lamps refer to a wall lamp that can be plugged into a wall socket, that is, a wall-mounted lamp that can be used by connecting to the power supply through a power plug without fixed wiring. This type of lamp is easy to install and move, and does not require professional electricians to install hard wiring. You can easily adjust the lighting position according to your needs. But this does not mean that it is completely wireless. It still needs to be connected to the power socket on the wall through wires to obtain electricity, but the installation method is simpler than traditional wall lamps that require internal wiring. Therefore, although it does not need to be permanently fixed inside the wall like fixed wiring lamps, the lamp body itself still relies on wires to connect to the socket, which is different from wireless lamps that rely entirely on batteries or wireless charging.
