The Daylight Tube consists of a dome rooflight with highly reflecting tubes and a ceiling diffusor that allow daylight to be brought into almost any room.
Thanks to ingenious bends and extensions, daylight can even be brought in through an attic or loft with the output changing around the clock and throughout the year.
The required light intensity depends on the tasks to be performed, but in general, one Daylight Tube in diameter 250 mm for 12 m² and one Daylight Tube in diameter 350 mm for 20 m² is advised.
