LED under-cabinet light Sky in a set of 2 with innovative Sonar dimmer The LED Sky under-cabinet lights consist of a square plastic housing that is just 8.5 mm high and therefore barely visible. The built-in LEDs emit a bright light that illuminates the surface below on shelves or under a kitchen wall unit. The set of 2 also includes a practical sonar dimmer. This can be fitted inside the piece of furniture and is operated by placing it by hand on the outside of the piece of furniture, so to speak. The maximum thickness is 4 cm and it can be operated through wood, Glas, stone and ceramic. Another feature of the dimmer is the memory function, which restores the individual brightness setting when the lights are switched on again. In addition to the dimmer, an LED transformer is also included to put the lights into operation.
