This product is hot dipped galvanised (dipped in molten zinc) after manufacture to ensure that it is truly weatherproof & will last for many years. The appearance of 'runs' & a roughness in the finish is a part of the process & is an intrinsic part of the product. With its elegant neck & clear oversized glass shade, the St Ives Swan Neck Light in Galvanised is a classy addition to our robust galvanised steel St Ives exterior lighting range. This classic wall-mounted light makes the perfect porch light & suits both modern & period homes. The St Ives Swan Neck Light’s hot-dipped galvanised steel body is completely weatherproof, making it suitable even for coastal locations. The light’s slightly rough finish & appearance of runs are as a result of the hot-dipping process & are an intrinsic part of its look.
