          Not cold weather friendly
          Installed last March and have enjoyed it right above my easy chair. This week we had a cold snap that got down to 25° 3 nights in a row. I happened to look up and saw a crack thru the glass and moisture all over inside. Very upset.

            Yes. Had one installed in my foyer coming in from the garage. An area with very little windows. Unreal how much light it gives off.

              Not enough light
              I had a light tube put in my living room a little over a month ago and I’m truly disappointed in the amount of light that comes in. I called the roofing company back and asked if I could get some kind of a different light screen and they told me that was the only one they carried. Then I get onto this website and see there are six different options. Can someone on here tell me which one gives the most light in the room?

              Thank you for taking the time to review this product. VELUX sun tunnel skylights do include a frosted diffuser system in the kit as standard. You can elect to purchase an optional sun tunnel diffuser to change the look of the light coming into your home, but this will be more of an aesthetic change versus increased light output. If you would like to discuss your particular application with VELUX, please call 1-800-888-3589 and our team will be happy to go over your options.
                I bought this a week ago and already it has enhanced the whole kitchen area whereas before I had to turn on the lights.

                    I specified a solar tube style skylight to be added to my main bathroom which has no natural light (no window) and was always dark until a light was turned on. This 10" Velux is amazingly bright on sunny days and does well on overcast days. This photo is from an overcast day and still lights the room. It also does not collect moisture when showering but I do have an exhaust fan with light but the mirror will fog even with the fan on.

                      We had Three 10 inch VELUX Sun Tunnel Skylight installed on Monday 10/19/20, one in the kitchen, two in the living room. They have truly added light to the rooms which was a great improvement for the area.

                        I just got my sun tunnel small living room and put 2 14” tunnels in . I used the diffuser that cane with the kit. The room is still dark is there any other diffuser I can get that will make room brighter . Where can I buy a brighter diffuser? Thank you
                        Response from Customer ServiceSep 29, 2020
                        Thank you for your review. VELUX has optional diffusers available beyond the stock one that will be included with your Sun Tunnel kit. These are more of an aesthetics change versus an improved lighting output. The TGF/TMF 014 Sun Tunnels use a flexible tubing and will have an approximate light output of 80 watts per system. If the tubing was changed to the rigid style, this would increase to almost 300 watts. (based on a 40 degree sun angle) This exchange would give you the increased light output you are looking for.
                          I can see the light
                          I was in the dark until I had two sun tunnels installed last week.

                            Let there be light and there was!
                            My house was so dark in the living area and due to the pitch of my roof, I wasn't able to have skylights. Sun Tunnels were the only option if I wanted more light. They are awesome! My friend even turned back the other day to remind me to turn out the lights then realized I didn't have any lights on. It was the Sun Tunnel.
