Used extensively at Mackintosh's 120 Mains Street, Glasgow, 1900, where they were originally covered gas lights. Mackintosh removed them to his house at 18 Southpart Avenue in 1906 where they were used with electric fittings. Similar designs were also used at the White Room of the Ingram Street Tea Rooms in 1900. Several other examples are in the collection at the Hunterian Art Gallery.
