The process of installing a light tunnel into the external roof surface of a property is similar to that of roof windows or Velux windows, so need not be a complicated process for a competent person or a good builder. It is an ideal solution if there are internal rooms without natural light such as bathrooms and utility areas and can be used to bring additional natural light to any area of the home.
The way that a light tunnel works is by directing sunlight down a reflective tunnel into an area which would previously only have been lit with standard lighting. An advantage to this sort of lighting is that it is free and does not require any energy to run it. Therefore, it is environmentally friendly and popular with anyone concerned with reducing their carbon footprint.
A light tunnel consists 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 is a device which spreads the light out 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 reflections as possible, as every bounce that occurs can possibly reduce the light produced.
