Parans Sunlight System
Parans delivers zero-carbon natural sunlight to indoor environments and buildings through industry-leading fiber optic light guiding and solar tracking technology. The system captures and directs natural sunlight into and through the home - deep into the building and away from the windows - and spreads the light in a way that creates an unforgettable experience that improves and enhances the living environment.

The SP4 series is specifically designed for large commercial enterprises, consisting of five models: SP4-8.2, SP4-12.2, SP4-16.2, SP4-24.2, and SP4-40.2. The SP4-40.2 model features 80 units of 100mm diameter light-collecting lenses, capable of delivering up to 100,000 lumens of visible spectrum natural sunlight and 800 watts of full spectrum natural sunlight per unit. Additionally, it integrates with the Parans Cloud big data operations platform, making it highly suitable for large commercial enterprises.
The PLT5 series is tailored for residential use, offering affordability, lightweight construction, small size, easy installation, and user-friendly operation. Ideal for spaces lacking sunlight such as basements, north-facing rooms, bedrooms, closets, living rooms, kitchens, and bathrooms. Available in two models, PLT-5 and PLT-5e, integrating 10 and 16 units of 100mm diameter light-collecting lenses respectively, providing up to 6000 and 9600 lumens of visible natural sunlight, and 80W and 160W of full spectrum natural sunlight. These units are lightweight, compact, cost-effective, feature automatic solar tracking, simple installation, operation, and require no maintenance, making them perfect for small residential areas.
Parans sunlight is entirely derived from natural sunlight, collected and transmitted through Parans' high-fidelity optical system, essentially retaining all spectral components of natural sunlight. It's genuine natural sunlight! This is unparalleled by semiconductor LED sources or any other traditional electrical light sources!

How It Works

Since 2003 PARANS has brought natural light to the indoor environment with the help of its green Swedish innovation – the PARANS system. With the new fourth product generation – the SP4 – you can bring natural light to every room, on every floor, in every building. PARANS’ solutions create unique indoor environments where the natural variation of outdoor sunlight is present.

Parans Solar Lighting offers sunlight for indoor environments through innovative technology and design. The system captures and leads the rays of the sun through the property – deep into buildings and far away from windows – and spreads the light in a way giving you a memorable experience.

The Parans system concentrates the sunlight, in a set of optical lenses mounted on a lens profile, into optical glass fibers. One lens per glass fiber. Four glass fibers are bundled into one optical cable that transfer the sunlight through the building to the specific room.
