- The tunnel is supplied with 2 x 45 degree bends.
- The solid tunnels have a diameter of 25 cm or 35 cm.
- The highly reflective coating on the inside of the tunnel ensures an internal reflectivity of 98%.

- Roof dome in acrylic or polycarbonate.
Bringing light to unusual places
Light tunnel for flat roof with fixed pipe. It brings light into areas of the house where it is not possible to fit a VELUX skylight. Ideal for bathrooms, hallways, stairs or cloakrooms.
Enjoy the changing daylight
Natural daylight makes your indoor spaces more pleasant and cosy to live in, artificial lighting lamps can't. Experience the changing light of the seasons and hours of the day with a VELUX light tunnel.
Natural light wherever there is a roof
You can add a VELUX light tunnel anywhere where there is a distance of 6m or less from the roof of your house to the ceiling. Hallways, kitchens, bathrooms, bedrooms, home offices - the only limit is your imagination!

Folds twice as fast
The new Flexi Loc system significantly reduces tunnel assembly time. The flexible light tunnel is easier to work with; it can now be moved and adjusted, while the installation process is more stable due to the possibility to interlock the components.

No need to enter attics or roofs
The new roof module with removable sash allows quick and easy installation from the outside. Lower the light tunnel to the desired position from the roof. No need to enter the roof or attic; now the light tunnel can be easily installed even in tight spaces where the roof cannot fit at all.

Easy to install and easy to clean
The VELUX light tunnel is easier to install thanks to the reinforced glass unit. When you're done, simply screw the protruding glass unit into place. As an added benefit, it is easier to maintain as it can be unscrewed and cleaned as needed.
