    Product description

    F 400 ULTRA POWER – special facade sun tunnel

    Facade F400 Ultra Power is extra powerful sun tunnel suitable for the facade installation. The optics of the sun tunnel is made by a jut if specially bent mirrors, which hoard up sun rays into the lens and then into the reflective tube.


    F 400 Ultra Power is constructed for the installation on the house facade and the horizontal conduction by reflective tube.


    The sun tunnel F400 Ultra Power is custom-made.


    Extremely reflective light tube and adjustable elbow

    Inside of the Lightway tube there flows sunlight into the interior. The inside walls of the tube are created by extremely powerful mirrors with maximum light reflectivity.

     The inside reflective layer is made of silver and silicon oxide, which are fixed by chemical vapor deposition in a vacuum. The layer will not or peel it or be warped by changes of temperature and 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 aluminum, 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 lenght can be as little as:

    • within 10 meters 0,5%

    • more than 10 meters 0,7%


    Glass ceiling diffuser – light diffuser

    The glass diffuser spreads light through the room and it prevents direct

    glare of light in interior. 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 color 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 color spectrum

    • white color trim


    Thermal isolation element Blue Performance

    The isolation element Blue Performance prevents thermal leaks through the pipe from the interior in winter. On the other hand in the summer, it prevents interior overheating due to excessive temperature. Blue Performance prevents water condensation in the space of the pipe and following water splashing into the diffuser and the ceiling construction. It is easy to connect the light tube to isolation element Blue Performance and a dimmer.

    • prevents thermal leaks and emoluments

    • coefficient of thermal permeability U 0,6W/m2K

    • prevents water condensation in the pipe of sun tunnel


    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.


    The dimmer of the light – optional accessory

     The shaft clamp inside of the pipe closes the supply of the light into the interior. It is easy to connect the dimmer to the refective pipe, adjustable elbow, isolation element Blue Performance or the diffuser.
