VELUX Support - Sun tunnels
My sun tunnel does not provide enough light compared to what I expected, what can I do?
There may be several factors which is limiting the performance of your sun tunnel. More information on this can be found by clicking here.
The natural light penetration cannot be changed or increased. However, VELUX can offer a light kit (ZTL), which can be installed inside the sun tunnel.
Please follow the step-by-step guideline on how to install the lamp here: Sun Tunnel Light Kit (ZTL) - Installation Instructions
