How long can a SunPipe be?
• A SunPipe can be almost any length that you wish, but loses 6% of light for every metre of SunPipe. For very long SunPipes, a larger diameter should be used. On smaller sizes the total effective recommended maximum length is 8m, and up to 20m on larger sizes of 450mm and 530mm. There is a 12% light reduction for every 45° elbow used.
