We purchase the Solatube and had it installed by the manufacturer, love it. We had a 14" one put in my sewing room with the prisim lense, it adds even more light. They were afraid it would be too much light but is perfect for my sewing room. At first we were constantly trying to turn the lights off, because it is so bright in there. We also had a smaller 10" with regular lense put in our master sitting area and our bathroom that did not have a window, I would totally recommend them. Not a huge difference with the heat but some with the prism lense.
