An E27 lamp extender is a simple adapter that allows you to lengthen the reach of an E27 screw-in light bulb within a fixture. It features an E27 male base that screws into an existing E27 socket and an E27 female socket at the other end where the light bulb is then installed. This extender is a practical solution for various lighting challenges, particularly when using larger bulbs in recessed fixtures or when you need more targeted illumination.
