...TUBUS is a system of lights in glass tubes. The tubes have a diameter of only 32 mm TUBUS offers a look of total transparency. But there is more behind it. It includes a clever optics which makes any glare impossible. The leds are working directly with 230 v. No boxes and no transformers on the ceiling are needed. Just one cable with line voltage is enough. The power is transfered to the next element. A line of 30 meters or more is possible with only one cable. It can be dimmed with standard phase-cut dimmers and if so the light is even getting warmer.
