Wall lamp Tube with cylindrical shade in opal glass In view of its simple, restrained design and pleasant lighting effect, the wall lamp Tube can be combined in many ways. Its small, angular wall holder holds a cylindrical shade made of opal glass. The light of the E27 LED lamp to be used (see accessories) emerges unhindered through the vertical openings. The glass also emits the light gently to all sides. This timeless light source was designed by Elio Martinelli and presented as early as 1977. The Italian architect and lighting designer is also the founder of the company Martinelli Luce, which produces the wall lamp Tube in excellent quality.
