How the Solatube Daylighting System Works


Solatube Daylighting Systems combine breakthrough optical technology with advanced designs and the highest quality materials to fill your living spaces with an abundance of pure, clear natural light. From sunup to sundown, daylight is harvested by a specially designed rooftop dome that uses our proprietary Raybender® 3000 Technology. The dome collects sunlight from any angle, selectively harnessing only the wavelengths we need to see, and filtering out those we don’t. It then redirects the sunlight through our highly reflective Spectralight Infinity Tubing, and delivers it to you in spaces never thought possible—like the bathroom, laundry room and kitchen. Solatube Daylighting Systems make these spaces brighter to give you the light you need to see better, accomplish more, and live better. Solatube...the brightest idea since the creation of the sun.

Raybender 3000 Technology

  • Patented daylight-capturing dome lens
  • Redirects low-angle sunlight
  • Rejects overpowering summer midday sunlight
  • Consistent daylighting throughout the day

Light Tracker Reflector

  • Innovative in-dome reflector
  • Redirects low-angle winter sunlight
  • Increases light input for increased light output
  • Unsupassed year-round perfomance

Spectralight infinity

  • most reflective tubing used in TDD's
  • 99.7% specular reflectivity
  • Purest color rendition possible
  • Allows for amazing tubing run lengths of more than 30 feet

Stylish Daylight Delivery

  • Form and function combine for optimal daylight diffusion
  • NEW Decorative Fixtures bring the beauty of glass to your interior
  • The Effect Lenses offer choices to warm ot soften the light
  • Add functionality with a Light Kit,Vent kit or Daylight Dinner

1. Capture

The story all begins with capturing sunlight. We challenged our engineers to develop a dome that automatically adjusts daylight harvesting throughout the day while achieving demanding thermal performance requirements. The solution? The most advanced dome technology with the ability to virtually bend daylight
LightTracker TM Reflector An innovative in-dome reflector that:
• Redirects low-angle winter sun-light for maximum light capture
• Increases light input for greater light output
• Delivers un-
surpassed year-
round performance

2. Transfer

How much does a bounce matter? You’d be surprised. 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. Its that attention to detail that led us to develop the highest performing tubing available.
Spectralight ®infinity tubing the most reflective material in
the world. Our tubing:
• Delivers 99.7% specular reflectivity for maximum sunlight transfer
• Provides the purest color rendition possible so colors are truer, brighter
• Allows for run lengths over 30 feet to deliver sunlight to lower floors
What are a few percentage points? A small difference in reflectivity value can make an exponential difference in overall light delivery of a tubular daylighting device.

3. Deliver

What makes solatube daylighting systems unique? The ability to offer amazing control over daylighting a space. Form light control to diffusion, we’ve thought of virtually everything you need to bathe a space in pure, natural light.
Stylish daylight delivery Form and function combine for optimal daylight diffusion with:
• New glass distractions decorative fixtures
• Warming or softening
effect lenses
• Ventilation, dimmer
or nighttime lighting
Superior color rendition The unique spectral reflectance characteristics of spectralight® infinity tubing reflect the visible spectrum without color shift to deliver the purest color rendition possible. It’s
performance like
this that ensures
that the color you
use in a space
will be vivid and
