The special large-area light collector
Lightway GALAXY 1200 – special sun tunnel
Lightway GALAXY 1200 is an absolutely unique piece of sun tunnel. The special large-area light collector with diameter 1200 or 1800 mm hoards up sunlight into the smaller diameter of tube.
The light literally gushes out from the diffuser into the interior. The power of the sun tunnel GALAXY is huge.
large-area collector providing enormous light power
the inside of the collector disposes of a reflective silver layer
antireflective optical glass Clearvision with nanolayer repelling impurities
designate for installation to the flat roof
The GALAXY sun tunnel 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.
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

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.
