All of Lumena’s stainless steel spike lights are made of high quality, marine grade stainless steel 316. They can accomodate longer than usual LED GU10s (240v) / MR16s, including high quality Lumena LED COB bulbs, and often have the option of an extension spike should a longer spike be required. Spikelights are a great addition to garden lighting, ideal for general spotlighting and can be used to highlight specific items in the garden such as statues or plants.
