These do allow some natural light. They do not give as much as the description says. I put in 4 on a pitched roof with full sun available. Also install is a little tricky as the TUBE can pull apart at the seams and is impossible to reconnect correctly. I had to just use metal tape and tape it back together. If the unit came with clear glass it might be a bit brighter. I am considering switching out lenses.
Bought 10 of the ODL 10" tubular skylites. Of the ten 4 had the solar power closure and night-light. Upon arrival, one of the boxes was significantly creased and opened. Both tubes in that box were damaged beyond repair. I called ODL and they were excellent in sending out replacements. Installation was on new construction. Some points not listed in the instructions. The tubes are wrapped on the interior with plastic to protect the reflective surface. This wrapping goes IN BETWEEN the rotating joints in the pipe. IT is CRITICAL to get that plastic out of the joint. When pulling the plastic out, the joint cuts the plastic leaving a 3/8" wide strip in between the joints. This will impede on turning the pipes to get the angle you need for installation. I ended up using a dental pick and carefully compressed the tube slightly on a flat surface and then hooked the plastic and pulled it out of the joint. Even with all the plastic out you will still have some difficulty in rotating the pipes when the angles are extreme. The fit of the jonts could be far better. I had 2 tubes fall apart when rotating them . Its IMPOSSIBLE to reassemble them after they fall apart. I didn't look at all ten units upon arrival. The boxes looked OK only to find the last 2 units were also damaged beyond use. I called ODL and left a message as it was Labor day Wk-nd, somewhat corse in what I had to say. Customer service was great in getting back to me on the following Tuesday and sent out 2 more sets of tubes. They could really inprove their packaging. The units allow substancial light although I won't see the full affect until the house is drywalled. I love the concept and the product, just wish the quality was better and the delivery. The people at ODL treated me very well. The power units work as described. Visitors are very impressed when seeing the product.
