My brother & SIL has one in their kitchen, and one in the upstairs bathroom.

Every time I use the restroom I try to turn on the lights.

Wish I could install them in my place, but sadly I live in a rented condo.

My place came with them already installed. I got used to my old mother telling me to turn off the light all of the time. They don"t heat up the room like a conservatory does and they are quite tolerable and very common in our country, as hot as it is.

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.

Before and After of Solatube
 

This is a before and after one of the sewing room and one in our master bedroom sitting area.

Had them for twenty years in our living room love them

My first house had this kind of heat.... I LOVED IT!!!!!!!!! Even living in Ohio.........The best part was not having to dust so much.....More time for sewing...lol

Also arranging furniture is easier. No ducts to arrange around.

Just wondering how the solartubes do at night. Do you not need a nightlight in the bathroom at night then? I think this might be a good idea for your bathroom. The only room in the house without ceiling heat.

You can definitely see a little light but not really enough for a nightlight.

If there's a bright full moon, there is enough light for a night light. If there's a little sliver of a moon, there is not enough light for the night light.
