This is our first pendant design to include glass and we are absolutely over the moon at how it has turned out. As with all of our designs, the materials and finishes that are used to create this light have been very carefully selected and sourced to really bring together an exceptionally high quality item that represents everything that we aim to achieve. The key elements of this design are the braided flex, square twisted chain and solid metal ceiling rose and lamp holder. We offer a selection of lengths or can make to a custom length on request. The finish in the pictures is Antique Brass but other finishes can be selected when ordering. The square twisted chain used on this design is of very high quality and quite hard to alter without the use of tools. We therefore recommend selecting the most suitable lentgh for your project. If you require a bespoke length please get in touch and we would be more than happy to help. The glass shade diameter is 30cm. The total length of the pendant in the product images is 80cm from the ceiling up to the furthest point of the glass shade. It can be adjusted to make it shorter when fitting. If you require longer please select a longer length. The base diameter is 100mm. The base is E27/E26 designed for Edison screw bulbs. The pendant is a metal class one fitting recommended voltage of 120V or 230v. (Will work in the U.K, U.S.A. and many other countries.) The pendant comes with a selection of fixing screws and accessories, but we recommend installation is carried out by a qualified electrician.
