This product features a socket for E14 light bulbs. You can insert or screw in 1 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. To make your decision easier, we offer a suitable selection of light bulbs in the light bulb section on this page, or you can simply add this product to your cart to receive a curated selection of light bulbs. The advantage of this design is that if a bulb fails, you can easily replace it with an inexpensive light bulb 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. You can often choose from a wide range of bulb shapes and light colors as well.
