Nellie linear LED concrete wall lamp with up- and downlight With its concrete surface, Nellie is a perfect addition to industrial interiors and is a light source that otherwise has a really modern look due to its linear shape. We are actually familiar with concrete from other contexts, primarily from newly built architecture. However, it has been successfully demonstrated for some time that lights with concrete components can also cut a really good figure. Efficient LED bulbs with a G9 base, which are included, are used as the light bulbs. The light, which is directed both upwards and downwards, has a warm and welcoming effect.
