I have three Solar tubes which has made a real difference in my house,making it much lighter. I thought I wanted another one in my living room and asked the opinion of the technician that came to my house to check something else for me. He pointed out to me that where I wanted the solar tube placed would make my fan unusable because it would give the effect of a strobe light and he didn’t think I would be happy. I really appreciated his honesty instead of just agreeing with me and making the sale. I would and do recommend the Solar guys to friends.
