Our solar tube was installed the Friday after Christmas. The installer arrived when he was scheduled. After a brief discussion as to where to place "the tube", (We are having our bathroom remodeled.) it took him about three hours to do the job, I assume. I had to leave and had no reservations leaving the installer here alone. When I got home, as I walked up the steps, I remember thinking the workers left the light on in the bathroom!! The tube lets so much light into the bathroom. I love it, and the experience was so positive I have no problem recommending Capital Lighting to anyone who asks.
