Choosing the right system

Choosing the best daylight delivery solution for your home

Solarspot® D-25 – 250mm sun tunnel

The Solarspot® D-25 daylighting system is the smallest diameter in the range and designed to fit between the closest rafters or joists. Despite being only 250mm (10ins) in diameter it will deliver an astonishing amount of light – up to 50% that of its nearest competitors and at least 10 times more than a larger diameter flexible-duct system.

The Solarspot D-25 is designed to provide daylight for areas up to 12 square meters making it perfect for those areas that are often not able to have windows, en suites and landings being the obvious examples.

The Solarspot® D-25 is ideal for lighting;

  • Bathrooms and en suites
  • Cloakrooms and shower rooms
  • Corridors and lobbies
  • Landings and hallways
  • Dressing rooms and walk-in wardrobes

Solarspot® D-38 – 375mm sun tunnel

The Solarspot® D-38 system is the larger of the two domestic sizes and designed to fit between standard rafters or joists (400mm). At 375mm (15ins) in diameter it will deliver significant levels of daylight for larger residential spaces and small to medium commercial spaces. Due to its exceptional levels of daylight delivery, the Solarspot® D-38 is comparable, if not superior, to systems that have significantly larger diameters.

The Solarspot® D-38 can provide enough daylight for spaces up to 22sqm and is the brightest, most efficient sun tunnel system in the 350-450mm catagory. In fact, in tests at the respected BRE the D-38 was proven to deliver around 69% more light than the Solatube 290DS.

The Solarspot® D-38 is ideal for lighting;

  • Bedrooms
  • Wider corridors
  • Larger bathroom and toilet areas
  • Kitchens and living spaces
  • Offices and study areas
  • Workshops
