Sunpipe and Sola-vent
We have installed both the Sunpipe and Sola-vent into our home.
The delivery was prompt and the packaging super, no damage reportable.
The installation was straightforward for anyone with some DIY skills although the time suggested installation should take is a little out, I would give a day for each first time around; if you get proficient then a pair of diyers should take about three hours for a Sunpipe, four or five for a sola-vent.
In use they do what they say on the packet and work well in any light situations, even illuminating areas using the streetlight as a source.
