Solatube Tubular Skylight: Bring Natural Light Indoors | DIY Guide 2026

Natural light makes rooms feel brighter, reduces eye strain, and cuts electricity costs. Unfortunately, some spaces—like hallways, entryways, and attics—can’t get enough daylight through ordinary windows. The Solatube® tubular skylight captures sunlight on your roof and pipes it inside without losing quality, maximizing indoor illumination even on cloudy winter days or when the sun is low on the horizon.

A specially designed acrylic dome is placed on the roof in the best spot to collect sunlight. The light travels through a highly reflective tube and reaches a ceiling-mounted diffuser that looks just like a regular light fixture. The system is maintenance-free, provides thermal and acoustic insulation, and can be customized with different domes and diffusers (from smooth to faceted). Installation uses no visible fasteners.

You can add extension tubes and adjustable elbows, and even install motorized dimmers to control brightness. There’s also a ventilation kit and an artificial lighting kit that turns the diffuser into a regular light source at night.

Flashing for Every Roof

Solatube® flashings are made from a single, seamless block for superior weather resistance and a perfect seal on flat or sloped roofs. They work with membrane roofs, metal roofs, and tiles. Besides providing complete protection, they’re designed to have a low visual impact on your roofline.

Solatube® Technology

• Raybender® 3000 Technology: A special lens captures light even at low sun angles and eliminates glare.
• LightTracker™: A reflector inside the dome catches and redirects low-angle light, boosting brightness.
• Spectrallight® Infinity Conduits: Deliver 99.7% specular reflection and pure color quality, transferring light up to 15 meters (49 feet).
• Indoor Diffusion Solutions: Lenses and optics provide wide light spread, block harmful UVA/UVB rays, and ensure visual comfort.

What You’ll Need for Installation

Before you start, make sure you have the right tools and safety gear. For a smooth DIY project, check out our home improvement collection for sealants, flashing, and tubing accessories. If you’re working on the roof, don’t forget garden supplies like sturdy gloves and a harness.

Choosing the Right Diffuser

The diffuser style affects how light spreads in the room. For a soft, ambient glow, pick a frosted or faceted diffuser. Need to highlight a specific area? A clear lens works best. Browse our lighting collection for compatible diffusers and dimmer switches.

Adding a Ventilation Kit

Solatube® offers a ventilation kit that pairs with the skylight to improve airflow in bathrooms or kitchens. To complete the setup, consider bathroom vanities and mirrors that complement the fresh, bright look.

Outdoor Applications

Use a Solatube® to illuminate a covered patio or shed without running electrical wires. Pair it with outdoor patio furniture and outdoor decor for a welcoming space. For more permanent structures, check out sheds and greenhouses that benefit from natural daylight.

Nighttime Lighting Solution

The artificial lighting kit lets you use the same diffuser as a regular light after sunset. To match your interior style, explore ceiling lights and wall decor that create a cohesive look.
