Parans Fiber Optic Skylights Bring Natural Light to Dark Spaces

Parans - Huvco

Update 8/08/2012Parans is now available through Wasco.

The interesting thing about fiber optic lighting is that it creates the ability to put natural light in places where there is none.  Generally, here’s how it works.  Using a building-mounted panel with computer-controlled, sun-tracking lenses, natural light is channeled through optical fibers to luminaires that diffuse the light (see diagram below).

Since early 2008, HUVCO Daylighting Solutions has been offering a fiber optic lighting system like this, or the Parans System, which was developed in Sweden.  Although light only travels about 60 feet through optical cables, the ability to direct light in this manner is quite interesting.


HUVCO provides a variety of options to both collect and diffuse light.  Cables can be routed through walls, ceilings, and subfloors, depending on your building set up.  And HUVCO also has hybrid luminaires that use both natural and electric light.

Natural light has been attributed to increased productivity and morale, better performance, and increased sales.  Additionally, using fiber optic natural lighting reduces the need to use electrical lights during the peak time of day, thereby providing the potential for reduced energy costs, depending on how much you’re paying for the entire system.

As a relatively new product, we haven’t yet seen any cost or ROI studies on the Parans System, but we will certainly keep you posted as this kind of information hits the market.  Anyone have experience using fiber optic lighting?

    As someone who hesitates to use solatubes, because I have to cut a hole in my roof, this seems like a very cool option. But, “computer controlled” sounds too expensive and complicated for me or most residential applications. I must learn more…….. I like it!

    I love this idea, and I think they look good too. but, would you have to wear SPF at your desk and in your living room etc.? would non white furniture be bleached? surely there is a UV filter involved.

      The glass itself filters out most of the harmful UV radiation but not 100%.

    This idea has been around for quite awhile, it just hasn’t been near as cost effective. 13 years ago (I don’t know how long before that this had happened) I had heard of an Asian scientist who’s office was in a basement. He had wanted to have some plants, but lacked the lighting to grow them. He tried fiber optic lighting, and to his surprise the plants grew remarkably better than normal. It was my understanding that the fiber optics filtered out harmful UV as well. It was my understanding that his seasonal plants were able to grow and produce year round under the conditions he created for them. I don’t remember the specifics, but it was on a documentary about past climates on earth and a few experiments based on the Asian mans findings were tried and shown to be successful. I can’t wait until this is more economically feasible for the average consumer for residential applications.

    Is a fiber optic system available to the general public for residential use? If so, where would we buy it and at what cost?


    Dear Sir:


    Kindly inform full details of this project as we want to purchase this project for our

    Best Regards

    Maybe, with this technology, we will be able to build underground bases which are lighted by this technology.

      I was going to say so. It would be a nice feature in an underground bunker.
      Sign of the times : previous posts are much more optimistic !

    This is awsome.
    We’ll try it to bring light to a vertical garden .. I’ll let you know.

  • rowhns

    i love this idea….i hope more office buildings and residential houses start using implementing it
