SOLARSPOT® D-650 is a tubular daylightin system, produced by Solarspot International S.r.l., designed for offices, classrooms, commercial applications and for larger areas for production, retail sales and warehouses. Each Solarspot® D-650 system can illuminate a space of approximately 50mq, with duct lenghts that can reach up to 20mt.

At just 676 mm in diameter, the D-650 adapts to most constructions avoiding any need for structural modifications and, thanks to the wide range of flashings available, it can be easily installed on any type of roofing. 

Solarspot® D-650 is usually supplied in pre-assembled kits 40+40 cm, to which it is possible to add straight extension tubes or angle adapters to make path deviations, according to the installation needs. Alternatively, Solarspot® D-650 is supplied in monotube configuration with 60cm of lenght. Two types of finishing are available: square with transition box or round with a "lamp" type diffuser for industrial locations. 

To increase the security conditions of the room where the Solarspot® is installed, it is possible to request the installation, under the dome, of an anti-intrusion system consisting of an adequate number of stainless steel bars, positioned radially and pre-assembled on the top tube.
