Leading sunlight

Sunlight has an immense impact on our wellbeing. It makes us feel better, learn faster, achieve more and become more productive.
At Parans, we want to make healthy sunlight accessible to as many as possible, as often as possible. While our technology is advanced, our solution is simple.

Sunlight Deep into Buildings

Parans lead natural light deep into buildings and far away from windows, with the use of highly intelligent technology. We use sun collectors and low intrusion fiber optic cables to lead the sunlight 30 floors down to make sunlight an indoor experience.


Through thin fibre optic cables we lead sunlight deep into buildings, turning unused property areas into profitable space- 30 floors down. It’s a minimum intrusion for a maximum light experience.

It’s a hi-tech system that makes the indoor environment more natural, in order to let the sun boost your creativity and productivity throughout the day, while lowering energy consumption.

It’s a way to fulfill daylight requirements, while opening up endless design possibilities within the building.

In every building and construction in which a healthy and sustainable environment matters, Parans’ solutions deliver unique values.

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.
