The Knapstein ELVI-S has a rotating and swivelling lamp arm. Its lamp head can be rotated and swivelled independently of the lamp arm via a further joint. A ball-and-socket joint is integrated at the base of the lamp, with which the floor lamp can also be swivelled completely. The ELVI-S has a lens through which the light is bundled downwards directly and glare-free. A cover with slots is integrated on the top side of the lamp head, which radiates light cones upwards. A white satinised glass filter is available as an accessory, which instead emits diffuse light upwards. The floor lamp is offered with matt nickel and chrome surfaces. A push button dimmer for switching and dimming is located on the light rod.
