The Knapstein ELVI-W wall lamp emits its light downwards through a lens. It is always glare-free and creates a wide light cone on the wall behind the lamp. The light is emitted upwards through a cover with slits in narrow light cones. A white satinised glass filter is available as an accessory, which can be integrated on the lamp head. With the glass filter, diffuse light is emitted upwards instead. The ELVI-W is available in matt nickel and chrome. The wall light has a height of 6.8 cm and a width of 9.3 cm. Its depth is 11.5 cm. Two LEDs, each with a colour temperature of 2,700 Kelvin extra warm white, are integrated as light sources.
