I have a solar tube in my kitchen as well as in my sewing room. I absolutely love them Half the time I don't even need to turn on my electric lighting at all. The natural light that is amplified is perfect to see the colors that I am picking out for my projects. I haven't noticed any heating in my room at all. My galley kitchen seemed like a black hole until I got the tube light in it. Both tubes were installed by my DH and went pretty quickly. I would recommend them to anyone wanting or needing more natural lighting.
