We have three SunTunnels (Velux brand) in our home. They were installed by the framer (who also had a roofing background). I think a good GC could do the install for you. We paid around $85.per Sun Tunnel to install( we were down to studs so labour was not that involved). One of the Sun Tunnels goes through a closet down to a lower floor. Even that one (which is also north facing) emits lots of light. I do think it is worthwhile.

As per radius of light, our home is a re-build that is not complete. Currently the SunTunnels do not have their ceiling cover on them. So the radius will likely increase when it is fully installed. Already it is around twice the radius vs the diameter of the Sun Tunnel.

We had Solatubes installed by their own reps and it was the best investment we made for our home in AZ! We paid around $2000 for 3 of them and it was well worth it! Took a dark house and made it so we didn't have to turn on lights during the day. LOVE them!

There are other brands.

Solartubes come in different sizes and different area of light provided. They have literature with examples.

I think Solartubes installers are certified, mine was.

I have one Solartube in a hall corner and two in the kitchen.

I paid $750 each, 10'years ago.

Just to clarify the prices I quoted above where just the framer labour charges (he was already here framing the house so it was an add-on). The material costs added to the costs, of course.

Lightway Solar tubes offer thermal insulation and double pane or triple pane glass.

Typical labor cost per Solatube are around 385.00 for a standard install (one story,composition roof and 8 foot ceiling) in the s SF Bay Area. Installation prices are built in for upgrades like light kits etc.

Recently bought a ranch house in Atlanta that received very little natural light in the bedroom and living room because of wide roof overhangs around the whole exterior of the home. I did a ton of searching, trying to find how to filter more natural light into my home. I find out through looking and looking on the net that these things called sun tunnels (similar to skylights) might be just what I need to get more natural light. Now that I know that they exist, my goal now is to find out what they do and how they work. Fast forward, there are several did decent brand names. The 2 most popular ones are Solatubes and Velux sun tunnels. They come in several different sizes 10", 14", 22". Most homes will use either the 10" or 14". Some of the other less popular brands will come in other sizes like 13", 24". They range in price from under $200 to about $500. They can be installed by a DIY'er or a professional. Professional installers charge for the total install including product and installation from around $600 to $1300 for one 10" or 14". I got about 4 different written quotes. One company came out but never ever got back in touch. The Solatubes and Velux have 10 year warranties, I was fortunate enough to see these installed in customers homes already and was able to talk at length with happy customers who has had these in there homes for as many as ten years with absolutely no problems. Some had the Solatubes and some had the Velux. Some had one installed and others had as many as 6 and again everyone was happy. One company offered the very best deal by lowering the price with a greatest discount if you buy more than one. One company online right now has a buy one you get a discount buy two you get a greater discount buy 3 and the discount is massive. I'm just sorry they weren't in my state.

I ended up getting 3 14" Solatubes installed by a certified installer, his price was reasonable, his service was great and he arrived just when he said he would. He was efficient and he knew exactly what he was doing. He worked alone and it took him about 5 hours to do 2 on a ranch. And it took him about 2 hours to do another on a 2 story home in the same neighborhood.

Also, there's a 30% tax credit available depending upon how you file your taxes.

I'm extremely satisfied with the installs and the amount of light is absolutely phenomenal. It has taken my dull and dark rooms to rooms that are now so bright that we need sunglasses (lol). I had strangers open up there homes to allow me to physically see what they look like, through the company referral. I am so grateful to them for that. If I could I would have an open house just to have people see exactly what they look like in a home.

If more info is needed just ask
