For Residential applications
The light coverage area varies among our Solatube® Daylighting System models. Keep in mind different light levels are required for different tasks. As a result, the approximate coverage areas are shown below for ambient light levels.
- Solatube Daylighting System 160 DS (10 in. / 250 mm) up to 200 sq. ft (19 sq. m)
- Solatube Daylighting System 290 DS (14 in. / 350 mm) up to 300 sq. ft (28 sq. m)
These estimated lighting areas are based upon an average 6 ft (1.82 m) tube length and 8 ft (2.4 m) ceiling height with the dome in direct sunlight.
Light output will vary depending on the intensity of the sun. For example, there will be more natural daylight at midday than in the early morning or evening. Light output may also decrease as the tube length increases beyond the recommended distances.

For Commercial applications
Please consult a Solatube Commercial Representative as acceptable illuminated areas will vary greatly due to ceiling heights and space uses. Our commercial experts are well-versed in application-specific Solatube design and light analysis for both new and retrofit projects.
