My family has some (tubular daylighting devices) in their house for years and every time I visit I comment on them. I decided to add one to our really dark bathroom and Natural Home Lite did a great job. I am so impressed how fast and the cleanup of the install. Excellent customer service, sales and install. Now our dark bathroom is no longer dark. I don’t even need to turn on the light during the day. This made a huge difference. I would recommend this product and company to anyone who needs a little more sunshine in your house.
