Installing VELUX Sun Tunnel tubular skylights is a great way to brighten any space with energy-efficient natural light. They are perfect for interior rooms like bathrooms, closets and hallways. The TGR skylight has rigid tubing and its low profile metal flashing blends into the roofline.
Super energy efficient model with quad diffuser to meet Energy Star requirements
New VELUX Flexi Loc tunnel connection system cuts installation time in half
Rigid tunnel is highly reflective and provides brighter, whiter light output in any application
Ideal for installations that require longer tunnel lengths
Assembled tunnel length with kit is 48 in. including the elbow sections
So, I spent the last few days installing two of these skylights and two 14" ODL skylights. We put three into a friends mobile home and one into my house. The Velux was superior to the ODL as there was about an extra 5" between articulation points.
The ODL had rather tight articulation - that's to say that the elbows are towards the end of the tubing. The plastic coating that covers the inside was put on prior to them assembling the tubes, which made it extremely difficult to articulate the angle prior to removing the film. Removing the film was difficult, as the metal was riveted together over the film. You're best bet is to gently push the metal in around the articulation joint as you pull out the film. IF you get the film out, then it will be easier to turn. Pulling the film out of the Velux was much easier and the elbows turned easily.
The Velux comes with two articulation elbows and a 24" section of metal that you have to assemble with self tapping screws. This turned out to be much easier to use that the ODL, which had two long sections, which are connected, with one being marked TOP and one being marked BOTTOM.
You'll need to buy extra tubing if there isn't an overlap of 2". I had a 2" gap and had to pay for an additional extension.
The Velux has a nicer METAL (vs plastic) roof boot. The Low Profile Flashing worked great on the pitch of his mobile home. The Velux has a larger dome. It has a more diffused diffuser over the ceiling part, which is in fact two pieces of plastic sandwiched to about 1" thick. The ODL has a piece of glass that has small bumps, which refract more like tiny diamonds. In other words, the Velux had a more evenly scattered light falling on the objects around. However, the major difference in my opinion is that the tube/dome in the ODL gives off a bluish cast. The light coming in from the ceiling, looks like a very blue fluorescent tube light. The Velux light was much more evenly cast and gave off a more natural color.
The Velux also had much higher quality components, with four packs of screws (some were self tapping), whereas the ODL didn't even come with self tapping screws. I bought the ODL for my house, as I didn't want to wait for the extra week for it to ship. Big mistake. If I could take back the ODL for the Velux, I'd do it in a minute.
A note on installation: if you can get a straight shot up from the ceiling, it will be your best choice. Any articulation (I had to move 7" off center over a 52" span because of a roof truss) makes for a major headache in installation and gaps where the metal doesn't fit tightly. Two of the skylights we put in had this difficulty (which was more difficult with the ODL). The two that went in straight we could have easily done in two hours. Another note, don't do like some videos show and pull off all the roofing material above. Simple lay the roofing boot over your spot on the roof, upside down, and mark the radius with a crayon or chalk, then cut it out with a reciprocating saw. Put into place and seal it up.
Both products made a dramatic difference in the lighting in the rooms that they were placed in. People kept looking for the new light switch before realizing that it was just the tubular skylights.
Given the difference, I would definitely spend the extra $50 for the Velux.
The far left dome is the ODL, the two closer ones are the Velux.
