Leading sunlight

Sunlight has an immense impact on our wellbeing. It makes us feel better, learn faster, achieve more and become more productive.
With Parans, architectural lighting designers can now lead the sunlight deep into buildings, far away from windows to allow everyone to enjoy the natural daylight.

Sunlight Deep into Buildings

In every building and construction in which a healthy and sustainable environment matters, Parans’ solutions deliver unique values. We use sun collectors and low intrusion fiber optic cables to lead the sunlight 30 floors down to every room, on every floor, in every building.

If you need to lead daylight more than one floor down. If you don’t want to have extensive intrusion on your rooftop – Parans is the solution.
