Steel Box is a wall mounted lamp, emitting light upwards at a wide angle. It is designed to create ambient light indirectly by the beam of light reflected from the ceiling and the wall, where it is mounted. It is suitable for illumination of hallways, staircases and passageways which need creation of an alternative illuminated atmosphere, as well as ambient lighting in the main rooms. It can be used as an alternative to the general lighting to create a comfortable environment when working with a computer. Its minimalist appearance makes it suitable for mixing with various interior styles.
