Stiff TW metallic LED wall light with touch dimmer and adjustable light colour The Stiff TW LED wall light is a modern light source for living rooms and lounges, both visually and functionally. The long, curved light element has a satinised acrylic cover. It can be rotated so that it is either flush or crossed in front of the wall mount. It can be mounted vertically or horizontally and the light output can be continuously adjusted using the push-button on the frame. This can also be used to set the colour temperature in three stages to 2,700 K, 3,350 K or 4,000 K.
