How a Solatube® Skylight Works

solatube isn nightlight

Solatube,” “light tunnel,” tubular skylight,” “light tube,” “sun pipe,” or “daylighting system,” is a tubular daylighting or night-lighting device that captures the sun’s rays and uses them to illuminate the interiors of homes. In its most basic form, this unique device is made up of a dome, tubing, and a diffuser.

Solatube tubular daylighting devices—or TDDs for short—are affordable, high-performance lighting solutions that bring daylight into interior spaces where traditional skylights and windows simply can’t reach. TDDs have become the ideal solution for lighting interiors in a cost-effective, energy-efficient and eco-friendly way because they significantly reduce the need for electricity while keeping people connected to the outdoors.

Selecting the right TDD for your residential or commercial project is a crucial decision, and Solatube Daylighting Systems are the superior choice because they are the only high-performance daylighting devices that utilize patented optical technologies to significantly improve the way daylight is captured and delivered to interiors.

The Solatube is designed to maximize light output at any time of day. It effectively captures low-angle sun rays in the morning, late afternoon and winter months with the help of the LightTracker Reflector, and collects high-angle rays at midday for powerful performance. It is recommended for use in spaces where variances in light levels don’t create an issue for occupants.

The Solatube Skylight Process Explained:

The complete process and functioning of a Solatube consists of three major steps:

Capturing sunlight is of course the first step. The most advanced dome technology has the ability to virtually bend daylight. LightTraker reflector is an innovative in-dome reflector that:


  • Redirects low-angle winter sunlight for maximum light capture
  • Increases light input for greater light output
  • Delivers unsurpassed year-round performance
  • Raybender Technology, a daylight-capturing dome lens that:
    + Redirects low-angle sunlight for maximum light capture
    + Rejects overpowering summer midday sunlight
    + Provides consistent daylighting throughout the day


After capturing the required sunlight, the next step is of course transferring it. Every time a ray of light is reflected, a small amount of that light is lost. And even a few percentage points in reflectivity make a huge difference in overall performance. It’s that attention to detail that led scientists to develop the highest performing tubing available. A small difference in reflectivity value can make an exponential difference in overall light delivery of a tubular daylighting device.


What makes Solatube Daylighting Systems unique? The ability to offer amazing control over daylighting a space. From light control to diffusion, you can think of virtually everything you need to bathe a space in pure, natural light. For a stylish daylight delivery form and function combine for optimal daylight diffusion with:


  • New Stylish Ceiling Decorative Fixtures
  • Warming/Softening Effect Lenses
  • Ventilation, Dimmer or Nighttime Lighting Options
  • Superior Color Rendition


Whenever, you decide and make your mind to get benefits of Solatube system, always ensure that you select a system with the most reflective material, a difference of just one percent will make a massive difference to the light delivered, particularly over longer lengths.
