How much light
a sun tunnel give you?Kalkulátor osvětlení

The amount of light that leads to your houme is determined by two parameters. These are the size of the sun tunnels and the number of sun tunnels.

The sun tunnel size is labeled with a Lightway number for a given type of sun tunnel. Choose from 6 sizes: Type 200, 300, 400, 600, 800 and 1200. The exact diameters of each type of sun tunnel can be found in the products information.

Here you can choose from 3 ways to find the size and number of sun tunnels to illuminate your home with sunlight.

  1. Power table
  2. On-line light calculator
  3. Professional calculation for a particular building.

Standard applications with a tube length of 1250 mm.
For types 200 HP, 300 HP, 400 HP, we recommend a tube length of up to 10 m.
When using LW 600 and LW 800, the light is efficiently fed within 25 m of the roof dome.
Lightway Maximus 5000 allows you to effectively lead light up to 80 m from the roof dome.
