A light tube (known as a skylight in Australia) is a brilliant concept patented by an Australian company in the 80s. Rain or shine, this system distributes light uniformly throughout the day without any use of energy and without any heat transfer. It is very common in Australian houses and mainly used to increase the amount of natural light into an otherwise darkened room. Actually Australians are usually extremely environmentally savvy. When the time comes to leave a room and "turn off the light", the uninitiated can easily spend a few minutes looking for a switch ... that does not exist (tested and approved by iPhoneography Oz)! To give you an idea, this photo was taken in the late afternoon in the toilet room of a house. No filter has been applied on the photo. Simple and clever concept, in total harmony with the environment, we love it!
