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 apart of the process & is an intrinsic part of the product. Part of our robust galvanised steel St Ives exterior lighting range, this Down Light is a neat little wall-mounted light that can be used anywhere inside or out where you need some extra focus. Simply designed & very reasonably priced, it is particularly good for lighting up pathways & corridors. The St Ives Down Light's hot-dipped galvanised steel body is completely weatherproof, making it suitable even for coastal locations.
