Challenges of bulb compatibility
In daily life, we often encounter the problem of incompatible bulb interfaces. Different lamps and bulbs may use different interface types, which brings a lot of inconvenience to our lives. This article will introduce a E27 to E40 socket adapter to help you easily solve this problem.
Common bulb interface types
On the market, the most common types of bulb connectors are E27 and E40. The E27 interface is usually used for household lamps, such as table lamps, chandeliers and wall lamps, with a diameter of about 27mm.
