Lumena offer a very impressive selection of high quality stainless steel outdoor lights in many different designs, many of which are Marine Grade Stainless Steel (316). Grade 316 stainless steel is a popular choice for outdoor environments due to its greater resistance to pitting corrosion which some lower grades may be affected by.  It is also an insulator of electricity and heat which is required for outdoor lighting to ensure fittings are safe and effective. It is a very durable material which is easy to maintain. To add further protection from weathering, a coating of clear lacquer can be applied.
