Glass dome made of Bohemian Crystal

The sun tunnels Lightway Crystal are unique, thanks to the crystal dome. It is made of Bohemian crystal and it collects 30% more natural daylight that polycarbonate equivalents. It is resistant against aging even in intense U.V. light and weather conditions. Both the crystal glass and the design of the domes create the properties that allow that natural light (even when cloudy) without distorting the natural colours of daylight..

The surface of the crystal is polished and hard, so smog or impurities do not stick to it, that’s why it needs almost no maintenance. The crystal dome does not turn yellow after a few years and emits the same light for decades.

High reflective light tube and adjustable elbow

The Inside of the Lightway tube is a mirror created by electro plating of silver & silcon oxide, allowing maximum light reflectivity and lifetime stability. This reflective layer will not peel or be warped by changes of temperature or humidity.

Connecting the light tube to the adjustable elbow, Blue Performance insulation and a dimmer is easy due to systematic connections, which is a standard part of package.

Technical information

reflection of reflexive layer of the pipe 99,8%

ray diffusion during reflection in 45 angle in pipe <6%

  • the basic material is aluminium, 99,7%
  • overall maximum distance of sun pipe is up to 80 meters, including 2 adjustable elbows 90° direction change of the conduit. The conduit of the tube can be vertical or horizontal without any effect on performance.

 The loss of light affected by tube length can be as little as:

  • within 10 meters 0,5%
  • more than 10 meters 0,7%

Glass ceiling diffuser – light diffuser

The glass diffuser distributes light evenly throughout the room and it prevents the direct glare of lightr. It is made of glass, that’s why it doesn't turn yellow and it lets the sunlight through well without any loss on light intensity and any change on the colour spectrum. The diffuser is already assembled with the tube of the length 200mm. It is easy to connect the light tube to isolation element Blue Performance and a dimmer.

  • it is made of sodium-potassium glass
  • does not turn yellow, does not change colour spectrum
  • white colour trim

Additional LED light

 It is used for illumination in the time of year when it is dark outside. Your sun tunnel Lightway will do the function of the sun tunnel as well as the ceiling light.
