These E27 lampholders are a robust upgrade from the standard two-part 'snap together' versions, featuring screw terminals for easy rewiring. Designed for use where a lampshade is not needed, they are ideal as replacement lampholders in various applications. With a 10mm threaded entry, they mount securely on standard all-thread fittings. The lampholders have a smooth skirt design and measure 40mm in width and 57mm in height.
