Revolutionize Your Home with a Tubular Daylighting Device

A brighter, more energy-efficient home is something we all strive for. After all, natural light not only enhances the ambiance of your house but also reduces your family’s energy consumption and promotes a healthier living environment.

With this in mind, it is perhaps no surprise that tubular daylighting devices (TDDs) have become more and more popular in recent years. These innovative systems can help you bring some much-needed light to areas of your house that were previously dark or dim.

But what exactly is a tubular daylighting device? How does it work? And what impact will it have on your home and the lives of your loved ones? Read on to find out!

 

What Is a Tubular Daylighting Device?

A tubular daylighting device (TDD) is a highly efficient lighting system designed to capture natural sunlight and transport it indoors through a reflective tube, illuminating spaces that might not have access to direct sunlight.

Unlike traditional skylights, which require large openings in the roof, TDDs use a smaller, compact design that allows them to be installed in almost any part of the home, including rooms without windows or in awkwardly shaped spaces.

The basic structure of a TDD consists of three main components:

  1. A rooftop dome
  2. A reflective tube, and
  3. A diffuser

The lighting process begins with the dome, which is typically mounted on the roof. This dome is designed to capture sunlight from various angles throughout the day, even when the sun is low on the horizon. Once sunlight is collected, it is channeled through the highly reflective tube, which is typically coated with materials like aluminum to maximize light transmission. The tube can extend through attics or crawl spaces, directing sunlight to the intended interior room.

At the other end of the tube, a diffuser, usually mounted on the ceiling, disperses the sunlight evenly throughout the room, creating soft, natural illumination.

The result is bright, energy-efficient lighting that reduces the need for electric lights, even in spaces that traditionally rely on artificial lighting.

 

Understanding the Benefits of a Tubular Daylighting Device

If you opt to install TDDs in your home, you’ll enjoy a wide range of exciting benefits, like:

  • Increased Natural Light: TDDs channel natural sunlight into areas of your home that typically lack windows, such as hallways, bathrooms, and closets. The result is a brighter, more inviting space that feels open and airy.
  • Improved Energy Efficiency: TDDs use natural sunlight to illuminate your property – reducing the need for artificial lighting during daylight hours and lowering your overall energy consumption.
  • Lower Utility Bills: People who install tubular daylighting devices in their homes usually notice a significant decrease in their monthly power bill.
  • UV Protection: Although they allow sunlight to enter your home, TDDs block harmful UV rays that can cause skin damage and fade furniture or flooring. This means you can enjoy all of the benefits of natural light without worrying about long-term damage to your property or your health.
  • Higher Property Values: Houses with more natural light are typically more attractive to potential buyers. Installing TDDs can increase your home’s appeal, making it a desirable feature if you ever decide to sell.

 

Tubular daylighting devices are also incredibly easy to install. They can be fitted to just about any roof in as little as a few hours – with virtually no disruption to your home or your family.

But which TDDs should you get? Well, for thousands of homeowners across the United States, Solatube’s tubular skylights have proved to be the perfect option. That’s because our residential daylighting systems come with features such as:

  • Raybender® 3000 Technology: Our patented daylight-capturing dome lens is designed to maximize natural light capture by redirecting low-angle sunlight, ensuring consistent daylighting throughout the day.
  • LightTracker™ Reflector: Our in-dome reflector enhances the performance of the system by redirecting low-angle sunlight during winter months, maximizing light capture when the sun is at its lowest.
  • Spectralight® Infinity Tubing: Made from the world’s most reflective material, this tubing delivers 99.7% specular reflectivity, transferring maximum sunlight into your home.
  • Integrated Solar Electric Module: Our device integrates a photovoltaic panel that collects solar energy, powering a smart NightLight feature that can be automatically activated at night.
