LED under-cabinet luminaire Linex Switch Tone with three white light colours It is particularly suitable for use in the kitchen or hobby room, because the Linex Switch Tone under-cabinet luminaire provides energy-efficient light in three colour temperatures. These can be adjusted in stages using the switch: 2,200 K, 3,000 K or 4,000 K. In addition, several luminaires can be connected so that only one power connection is required. Thanks to the memory function, the last light colour set is stored and reproduced the next time the light is switched on.
