    Once in it looks good

    No hole for light fixture. The 2d lens would not fit

    It's a total upgrade.

    I needed to change out several skylights that were 30 years old and cracking. I chose Solatube because they were local and had mostly very good reviews. I was impressed with the sample product. Efficient dual-pane hardened safety glass with argon gas. The old skylights were acrylic and didn't have any of the benefits of this modern product. I decided to replace all four skylights. They are a beautiful, modern replacement, brighter, properly sealed and secured. Noise reduction and house temperature improved considerably.

    I had my first Solatube daylight in my previous house in 1999. I then put in 3 more. Now, in my new house, so far I have 3 solatubes

    Solatube built to last!

    After more than 15 years with my Solatube, I’ve decided its time for an upgrade. My old skylight has served me well, but the new models offer so much more, including better energy efficiency and light control options.

    Upgrade was a piece of cake!

    My first Solatube tubular skylight about ten years ago, and it has been a game changer for natural light in my home. While I've loved it, I've recently learned about the newer models that offer better insulation and improved light diffusion.
