VELUX Support - Sun tunnels
How much daylight can I expect from my sun tunnel?
Estimating the exact amount of daylight a sun tunnel will bring into your room is challenging, as it depends on many factors, including:
- Local weather conditions
- Roof orientation (e.g. north, south)
- Roof pitch
- Sun tunnel size (10" or 14")
- Type of tunnel (flexible or rigid)
- Tunnel length
- Number and angle of bends in the tunnel
However, to give you a general idea:
A VELUX Sun Tunnel 0K14 (14"), installed under average conditions — south-facing roof, rigid tunnel, 45° pitch, 1.5 m length, and good weather — typically delivers light comparable to a 60W bulb.
