When remodelling a property, it may be that the situation arises that there is insufficient light coming into a room or that a window has had to be removed or blocked off. This can happen in a bathroom or toilet. Light tunnels, sometimes referred to as sky tunnels, sun tubes, roof lights or tube lights are a good solution to this problem and can be installed into any roof structure with the exception of thatched roofs.
The process of fixing a light tunnel into an external roof surface is similar to that of Velux windows, and can be installed by a professional or someone with some building experience.
Light tunnels consist of a roof dome connected to flexible or rigid reflective tubing leading down to an internal lighting unit. This lighting unit acts as a diffuser which spreads the light from its source evenly. The main purpose of the tube itself is to get the light from its source on the roof, down the tube and out of the internal diffuser with as few bounces as possible, as every bounce that occurs can degrade the light.
As any lighting that is provided by a light tunnel is free and does not require any energy to run it is environmentally friendly and therefore popular with anyone concerned with reducing their carbon footprint.
