This product features a socket for E27 light bulbs. You can insert or screw in one light bulb into the lamp. Whether a light bulb is screwed in or plugged in depends on the socket used in the lamp and the corresponding base of the light bulb. The advantage of this design is that you can easily replace a light bulb in case of a defect without having to disassemble the entire lamp. In addition to traditional light bulbs, you can also use dimmable bulbs or smart home bulbs that can be controlled in various ways. Furthermore, you often have a wide selection of bulb shapes and light colors to choose from.
