Tube wall light with cylindrical lampshade made of opal glass Thanks to its simple, understated design and pleasant lighting effect, the Tubes wall light can be combined in a variety of ways. Its small, angular wall bracket holds a cylindrical lampshade made of opaline Glas. The light from the E27 bulb (see accessories) escapes unhindered through the vertical openings. This timeless light source was designed by Elio Martinelli and introduced back in 1977. The Italian architect and lighting designer is also the founder of the Martinelli Luce company, which produces the Tubes wall light in excellent quality.
