The design has virtually unchanged since the introduction of electrical power, these lampholders give the period look whilst being fully compliant with modern electrical standards. All lampholders come with a shade support ring as shown. These are fully adjustable from the central arm screw point. They can be used either way up or down and are a direct match to conduit fittings. Each lamp holder will fit all lampshades with a 40mm aperture in the top. Just add an extra shade ring, which can be found in the fixtures and fitting section of the website. Base: 70mm diameter Horizontal length: 90mm Vertical length: 90mm (not including the bulb). At full length the whole fitting is 145mm long. 145mm Wall Projection E27 Fitting Manufactured in the UK.
