This product features a socket for E14 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 compatible 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 tailored selection of light bulbs. The advantage of this design is that if a light bulb fails, you can easily replace it with an inexpensive one without having to disassemble the entire lamp. In addition to traditional light bulbs, you can also use dimmable light bulbs or smart home light bulbs that can be controlled in various ways. You will often have a wide range of light bulb shapes and light colors to choose from.
