Solarspot® D-38 -
the brightest 350-400mm system in the world!

It’s official, recent tests at the independent Building Research Establishment, the Solarspot D-38 left the competition in the shade. With efficiency levels almost half as good again as the next best system, the superior patented technologies of the Solarspot delivered efficiency levels of at least 57%. Compare this to those of the Sun Pipe (44%) and Solatube (40%) and the Solaspot D-38 is the clear choice for larger domestic installations like kitchens and living rooms.

At 375mm (15ins) in diameter, the Solarspot ® D-38 system is designed to fit between standard rafters or joists (400mm) and will deliver significant levels of daylight for residential and 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 lights spaces up to 22sqm and is ideal for;

  • Bedrooms
  • Wider corridors
  • Toilet areas and larger bathrooms
  • Kitchens and living spaces
  • Offices and study areas
  • Workshops

A Solarspot system is the best way to bring daylight into a windowless landing or stairwell.
