L.E.S.S. Lighting is a Swiss based startup with an apparently novel new form of light source they call “nano fiber lighting”.

According to their site:

L.E.S.S. (“Light Efficient Systems”) introduces the next generation of distributed lighting systems as a new alternative to today’s LEDs or discharge tubes. Based on an active nanostructured fiber of the thickness of a human hair, our technology generates high quality light that exhibits both ultra-uniformity and brightness characteristics, surpassing today’s quality standards. In addition, the thinness of our fiber offers a high integration potential and unlimited design potential.

Here is an article on their history/success.

Their first products are focused on applications that require ultra-uniform lighting for inspection of small or microscopic objects.

I don’t get what an “active nanostructured fiber” is or how it produces lumens.  They are clearly playing this close to their chest.  I have no real idea, but I get this feeling from their website that their technology is fundamentally LED technology in a new form factor.  I will be most interested to hear them explain in detail the light source.
