The solar tube works well alright but doesn't add to the appearance of your house externally. I'd opt for a new Velux product- which basically looks like a normal rooflight from the outside but uses the solar tube idea (flexible aluminium tube/ duct) to funnel light into otherwise dark spaces. It'll cost a bit more bit does look far better. You can also include a light fitting in the tube which can be turned on at night. Paul Geoghegan is the Velux rep in Ireland, they used to have an office/ showroom on South Leinster Street.
