Product description

Signal SI400 table lamp - adjustable task lighting With the Signal SI400 table lamp from Jieldé, any workstation or work table can be illuminated effectively and purposefully. The light is a more contemporary and somewhat more delicate version of the well-known Loft light, which was developed in 1950 by the founder of the family-run company Jieldé from Lyon (France). His aim was to create a highly functional and yet very flexibly adjustable luminaire design that would make work easier. The original Loft table lamp became an industrial design classic and the Signal SI400 is in no way inferior to it. The robustly crafted light made of steel, aluminium and iron is the ideal option for lighting workstations. Several joints ensure the greatest possible flexibility in the alignment of the lighting: the light can be rotated by 220° at the base, swivelled by 300° at the two joints on the frame and the head can be rotated by 360°. The lampshade is white on the inside, so there is no compromise on the reflection of the light - fitted with a ceramic socket - made in France - each light is unique with a numbered plaque
